▼ Climate change is widely regarded as the leading global issue of the 21st century. There is now a general international agreement, supported by an overwhelming amount of scientific evidence, that the global climate is changing at an accelerated rate and that human-driven emissions of greenhouse gases into the atmosphere is the main factor driving this trend. Arguably the most devastating impact of climate change on the human civilisation will be a rapidly increasing rise in global sea levels, which are currently rising at an unprecedented rate, placing hundreds of millions of people at serious risk of
inundation in coastal communities across the globe. In the case of New Zealand’s capital city, Wellington, over ten percent of the city’s residents are at risk of displacement by the end of this century. This thesis aims to find a solution to resident displacement in the coastal city, addressing the question,
How can a resilient residential dwelling be designed for the coastal city, in response to the encroaching pressures of climate change driven sea level rise?
This research question and its subsequent design aims have been achieved through a highly iterative design process resulting the development of a connected network of amphibious dwelling solutions which provide the residents of the selected focus community of Kilbirnie, a coastal suburb in Wellington city, with the capacity to accommodate, adapt and thrive in the face of sea
inundation. Hereby ensuring the social sustainability of the coastal community, currently at serious risk of displacement as a direct result of climate change driven sea level rise.

▼ Over the last decade the world has seen three major tsunamis strike the coasts of
Indonesia, Samoa, and Chile. These tsunamis have caused significant losses of life and
property on the coastal cities of these and nearby countries. The NEES (Network for
Earthquake Engineering Simulation) Housesmash project was created to look at some of
the specific effects of the
inundation phase of a tsunami. Specifically the Housesmash2
project, which was conducted at the O.H. Hinsdale Wave Lab at Oregon State University,
looked at several different hazards and mitigation techniques for tsunami resilient design.
Some of the research from this project will be presented in the following two
manuscripts, each based on a small part of the project.
The first manuscript looks at the effect of small finite width engineered seawalls
which can be used as a mitigation technique to reduce tsunami induced loads such as
hydrodynamic drag by deflecting the incoming water over and/or around the wall, thus
reducing the bore energy. In this experiment 5 unique wall heights, cross shore locations,
and wave heights were systematically varied to determine the effects of each. From this,
the most and least important factors can be determined, which will help to design walls
that are the most efficient in reducing tsunami loads. The tests showed that seawalls can
substantially reduce the hydrodynamic loads, a reduction factor as big as 0.1(90%
reduction) was observed during testing. These results agree very well with published
field reconnaissance reports from the 2004 Sumatra tsunami. To make this research
useful for design engineers, equations were developed to predict the reduction in
hydrodynamic load on a structure. These equations use the offshore wave size, bore
height, wall height, and location to determine the reduction factor.
The second manuscript looks at the potently catastrophic effects of debris impact,
specifically impact from shipping containers. For this experiment 1:25 scaled shipping
containers were built to 7 different weights corresponding to 45% to 112% of scaled
weight of the ISO (International Organization for Standardization) legal limit of
30,400kg. During this experiment the mass, cross-shore starting location, starting
orientation, and offshore wave height were varied to better understand the effects of each.
Impact forces were recorded on a 1:25 scale model of a proposed tsunami evacuation
facility with open columns on the ground level. The containers were tracked as they
traversed across the beach and impacted the structure using newly developed optical
methods. Several published methods of predicting impact forces were tested against the
experimental data showing the accuracy of each. In addition new methods for predicting
impact forces are proposed based off of further analysis of the data set recorded.

▼ Since the end of the last century, polders in the Netherlands have suffered from
inundation due to heavy rainfall.
Inundation occurrences in 1998 have led to large economic losses, especially in polders with a fast rainfall runoff process due to the high percentage of land occupied by greenhouses. This thesis focuses on water system assessments, conducted in greenhouse dominated polders. The water system assessment is divided in a technical analysis (using a hydrodynamic model) and an analysis on the cooperation between the different parties involved in water management. The
inundation of 1998 had a large impact in the area managed by the water board of Delfland. As a reaction to the
inundation, policies were created containing storage capacity standards for the open water of polders. Based on these standards the project ABCDelfland (Afvoer- en Bergings Capaciteit Delfland, in English: Drainage and Storage Capacity Delfland) was started, in which water systems of main canals and polders were assessed. The polder assessment was aimed at reviewing if the new standards were met. In the assessment the water board focused on the water system under its own control. The focus of that study was not on how to solve the
inundation problem, but on how the open water system could comply with the standards. The solutions which were identified to make the water system meet the standards were financially not feasible. It was found that a better representation of the water system was needed to develop new solutions. Cooperation between the parties involved in water management would be needed to make this happen. This study was conducted to improve the assessment methods of rainfall fed
inundation in greenhouse dominated polders. It uses the Oranjepolder (located in the management area of the water board of Delfland) as a case study, since
inundation has occurred several times in this polder and is well documented and parties are engaged in finding new innovative solutions for the problem. In this assessment a form of participatory modeling was applied. Input for a new hydrodynamic model was given by all parties involved in the management of water in the Oranjepolder. The water board of Delfland is responsible for the management of the open water, the sewer systems are managed by the municipality of Westland and horticulturists influence the runoff to open water by the storage of water in basins. By sharing information and experiences during workshops, this research has been made possible. Through the cooperation of these parties, the important elements of the water system and the key to future solutions are identified. A hydrodynamic model of the Oranjepolder with a high level of detail is achieved. All important hydrologic processes are included. The hydrology of greenhouses is included on an individual level, resulting in a runoff to open water which represents the actual situation. Secondly, the channel flow model contains all channels and water structures located in the polder. This makes it possible to review

▼ The Okavango Delta is recognized as one of the famous inland wetlands and its sustainable use is important for socio-economic development of Botswana. The Okavango delta comprises permanent swamps, seasonal swamps, and drylands on islands within the delta and the surrounding areas, sustained by Okavango river inflows from upstream and local rainfall. TheOkavango River splits into several distributary channels within the delta. Areas which are flooded annually vary in response to varying inflows into the delta. Peak inflows into the delta occur during the February to May period. Due to the low gradient over the delta, these inflows move slowly resulting in peak outflows from the delta occurring during the June to August period. The inundated area over the entire delta increases from May until it reaches maximum inAugust and starts to decrease from September, reaching minimum inundated area in the months of December and January. The incoming flood wave into the delta and maximum
inundation is out of phase with the local rainfall season.Communities living within and around the delta derive their livelihoods from tourism, hunting, fishing, livestock rearing, and crop production. Crop production is carried out on drylands and within floodplains. Some of the households take advantage of the increase in soil moisture arising from this
inundation along floodplains to cultivate their crops as the floods recede. This practice is locally referred to as molapo farming which highly depends on
inundation of floodplains. The availability of floodplain
inundation highly depends on the magnitude of inflows into the delta and the local rainfall which are highly variable resulting in uncertainty regarding successful crop production, availability of livestock grazing areas, and uncertainty in reliance on the wetlands resources such as fishing. The uncertainty experienced in timing of extreme events which cause flooding of resulting in water reaching areas or floodplains where it is not wanted, and also uncertainity in timing of low flows, therefore water not reaching some parts of the delta.Several hydrological studies have been carried out with the aim of improving the understanding of the spatial and temporal dynamics of flows throughout the delta including predicting areas that are likely to be inundated each year. The significant gap addressed by this research is to improve the understanding of the spatial and temporal influence of magnitude and timing of flows on floodplain
inundation. Local rainfall on the delta is highly variable over time and space due to its convective nature. This research also addresses the rainfall temporal and spatial variations and its implications on floodplain
inundation. The knowledge about spatial extent and duration of floodplain
inundation should assist in predicting each year the viability of molapo farming. Three research site, Shorobe, Tubu and Xobe are selected as case studies to understand the dynamics of floodplain
inundation induced either by inflows or local rainfall. Local rainfall during…

▼ Floodplain forests of the Upper Mississippi River are characterized by complex interactions between biota and the physical environment, specifically aspects of hydrology. The role of environmental variation in overstory composition, structure, and growth is not well documented. Goals of this study were to 1) characterize current stand conditions along gradients of inundation and relative elevation, and 2) describe growth patterns of silver maple (Acer saccharinum L.) trees, and their relationship to hydrological patterns. Patterns of forest composition and structure were more similar for plots comprising similar environmental conditions than plots within a stand, suggesting that current methods of stand delineation do not capture the full extent of within-stand environmental variation. I found evidence that growth patterns of silver maple had positive relationships to hydrology at a plot-level and a stand-level. These results suggest that forest managers may need to “rethink” how they summarize stand condition and develop silvicultural prescriptions.

▼ In the last few centuries, many streams in the eastern United States have been severely disturbed by land use change and are now disconnected from their original floodplain due to the aggradation of legacy sediment. Currently, stream-floodplain reconnection is advocated as a stream restoration practice to take advantage of ecosystem services. The objective of this study is to compare two current stream restoration approaches for their nutrient flushing ability: 1) a conventional approach leaves legacy sediment on the floodplain; and 2) an ecological approach that involves removing the accumulated legacy sediment in order to restore the original floodplain surface wetland, revealing a buried A soil horizon. Soil cores were taken from the surficial legacy sediment layer and the buried A soil horizon in the floodplain of a 550-meter reach of Stroubles Creek in the Valley and Ridge province near Blacksburg, VA, to evaluate potential for flushable DOC, TDN, NO3-, NH4+, and SRP content. In addition, an
inundation model was developed to evaluate the extent of flooding under the two restoration scenarios. The
inundation model results and nutrient flushability levels were then used to simulate the release of nutrients as a function of stream restoration approach. Results indicate that the buried A horizon contained less flushable nutrients, but the ecological restoration would have a higher frequency of
inundation that allows for more flushable nutrient release at the annual scale. Understanding the nutrient release potential from the floodplain will provide the ability to estimate net nutrient retention in different stream-floodplain reconnection strategies.

▼ River floods are socially and economically devastating events, especially in highly developed flood plain areas, where they can cause significant losses and negatively affect local economies. In this thesis, a techno-economic model is presented for the estimation of flood losses to the rural and the urban sectors due to a flash riverine flood. At first, the MIKE FLOOD hydrological model was employed in order to simulate the river hydraulics, using the MIKE 11 one-dimensional sub-model, and the overland flow in the floodplain area, using the two-dimensional MIKE 21 sub-model. The coupled grid model was used for the inundation simulation of a specific flash flood event. A grid of square cells was employed for the representation of the study area and the flood inundation parameter values, maximum floodwater depth and respective floodwater velocity, at the time instant at which the floodwater depth maximizes, were simulated for each grid cell of the study area. Continuously, a grid-based mathematical techno-economic model, which takes into account flood inundation parameter values, as provided by MIKE FLOOD, provides monetary estimates of damage in rural and urban environments. More specifically, the techno-economic model for the rural sector takes also into account the season of flood occurrence and the crop type, whereas the model for the urban sector takes into account the building type. The techno-economic model’s monetary estimates of damage are based on synthetic flood damage surfaces generated by a combination of questionnaires and weighted Monte Carlo simulations.Due to the lack of historical damage data for the flood case study, a synthetic method was adopted for the development of the flood damage surfaces, which involved a questionnaire survey targeting practicing and research agronomists for the rural sector, and building experts, i.e. civil engineers and architects for the urban sector. The questionnaire-based survey generated rural and urban loss data based on the responders’ loss estimates, for several flood condition scenarios. By answering the questionnaire, the experts were in essence expressing their opinion on how damage to various crop types or building types is related to a range of values of flood inundation parameters, such as maximum floodwater depth and respective velocity. Subsequently, a Weighted Monte Carlo simulation was performed in order to enhance the questionnaire-based loss estimate information. The statistical properties of the generated synthetic datasets were identical to those of the questionnaire-based data. The data generated by the Weighted Monte Carlo method were processed via Logistic Regression techniques in order to develop logistic damage surfaces for the rural and the urban sector. The damage surfaces are an essential parameter for the estimation of the flood damages by the techno-economic model. The Python-based code combines the Weighted Monte Carlo method and the Logistic Regression analysis into a single code (WMCLR Python code). Each WMCLR code execution provided a…

▼ Rivers and wetlands are under considerable threat around the world from climate change, pollution, invasive species and overharvesting of water. Such complex problems demand development of tools to improve wetland management and recognize their ecological and ecosystem service values. Understanding the inter-relationships between freshwater ecosystems and human uses necessitates analyses of water resources at large spatial and long temporal scales, possible using classification of satellite imagery. The
inundation regime directly influences wetland type, critical for understanding long-term trajectories of change which affect the ecosystem. Landsat optical imagery is routinely used to map
inundation and wetlands across Australia, but cannot penetrate cloud cover or vegetation to detect all inundated areas. Contrastingly, synthetic aperture radar (SAR) imagery overcomes these shortcomings, but remains largely untested for arid areas. To address this gap in knowledge, I tested the effectiveness of using L-band SAR to map
inundation and wetland types in the Paroo and Warrego River floodplains within the Murray-Darling Basin, arid Australia. Data from the Japanese Advanced Land Observing Satellite (ALOS) Phase Arrayed L-band SAR (PALSAR) sensor were provided through the Kyoto & Carbon (K&C) Initiative to meet requirements of the RAMSAR convention on wetlands. I successfully detected
inundation in arid land cover types using segmentation and change detection of SAR L-HH/HV data to high accuracy. I used SAR data mining in a classification and regression tree analysis to differentiate arid wetland types with a high accuracy, validated with field data. Overall, the use of L-band SAR satellite data was effective for rapid flood mapping and discrimination of different vegetated wetlands, and clearly has wider applicability. I then investigated the flooding regime of the largest floodplain wetland in the system, Yantabulla Swamp, by mapping
inundation using a combination of ALOS PALSAR, Landsat, and aerial surveys; obtaining historic river flow records, local rainfall and evaporation data; and modelling flood volume to hindcast flooding regime over 4.5 decades (1970-2015). Yantabulla Swamp has a highly variable
inundation regime. On average, large episodic ‘boom’ events (>90% extent) occurred about every 3.1 years, medium-high events (>40%) every 1.6 years, medium-low events (<40%) every year, with a mean flood extent of 14.82% (SD=25.57). Some years were dry while others had multiple low spells within a year and the longest period between episodic (>90%) events was 7.21 years, reflecting the unpredictability of the system. Rainfall contributed occasionally as the sole contributor to some low extent events, while a combination of rainfall and flow from Paroo River and Cuttaburra Creek produced the largest and longest events. Overall there was a higher mean rate of rise (1.67%/day) compared to fall (0.33%/day) for individual events, showing slower recession. The combination of SAR and Landsat data successfully enabled modelling…

▼ The focus of this research is to provide solutions to the city of Campeche to decrease the inundation risks generated by a hurricane with an occurrence of once in fifty years. Campeche is a city located at the Gulf of Mexico on the Yucatan Peninsula. The rapid growth of the city is one of the reasons it is having troubles with the water and flood management of several areas throughout the city. Although the municipality has already executed some improvements to the drainage system during the last years, it is still lacking to cope with heavy rainfall and storm surges due to hurricanes at several areas in the city. In order to gain a better understanding of the location and the way it works in Campeche a location, stakeholder and political analysis have been performed. Boundary conditions, program requirements and preferences have been formulated based on this analysis. By examining hurricanes over the last decades, a hurricane has been simulated with an occurrence of once in the fifty years. In the situation characterisation the city has been divided into several catchment areas to determine their vulnerability (expressed in total amount of water accumulation), taking into account the capacity of the current drainage system in the event of such a hurricane. Four solutions have been chosen to elaborate. In this elaboration, calculations have been performed on the design and construction. For the implementation of the options suitable locations have been determined and the possibilities and risks have been defi ned. In order to test the elaborated solutions on socioeconomic factors in combination with ecology, safety and politics, a multi-criteria analysis has been performed. It can be concluded that all options differ a lot from each other. Every option tackles another side of the problem and therefore they score on totally different aspects. In the discussion, it is further elaborated what the supplementary advantages and disadvantages of the proposed solutions are. Using this, the integral system of water management measures is considered. A few fields can be found on which could be made an improvement in the future. Firstly, the political system requires short term measures to count on enough support. Besides, citizens should be kept informed and have to be made aware of the flooding problem. Drainage expansion needs to take place in order to relief the most crucial parts in the city from their excess of water during extreme weather conditions. Lastly, when expanding the city, the amount of green space and inundation risks of the concerning area should be always kept in mind.

▼ Coastal inundation models are benefited by timeliness of the predictions, not only when it comes to real-time forecasting but also considering risk assessment studies and sensitivity analysis. Numerical models however are often subjected to a trade-off between accuracy and efficiency, especially when dealing with large geographic scales. In this study a new strategy is proposed for simulating storm-induced coastal inundation on dissipative beaches with a simplified shallow-water flow model named SFINCS that is forced with water-level time series along an offshore boundary in the shallow nearshore region. By extending the model domain into the surfzone, the processes of wave runup and overtopping can be simulated in an efficient way using a two-dimensional alongshore-continuous model. SFINCS is validated for a number of one-dimensional and two-dimensional test cases using the process-based Xbeach model as a benchmark for validation. Runup predictions by SFINCS on one-dimensional planar beaches compare well with Xbeach after applying a correction for the short-wave induced setup at the offshore boundary. This correction can be estimated in advance using a newly derived empirical parameterized model. The accuracy of SFINCS in predicting mean overtopping rates on simple beach geometries is comparable to that of empirical models often used in the design of coastal protection works. SFINCS is able to accurately predict the maximum flooding extent for a number of storm scenarios at the case study site of La Jolla along the U.S. coast of Southern California. Predictions of the maximum flood depth correspond well with Xbeach, whereas maximum velocity magnitudes are significantly overestimated locally which can form a limitation for flood damage assessments. Future challenges include the efficient generation of wave boundary conditions for SFINCS and implementation into a larger modeling framework. A revision of the model code, which was tested for the first time in this study, is expected to yield improvements in computational efficiency. Validation using field data and further case studies along the coast of Southern California should provide more insight into the feasibility of a large-scale application of SFINCS.

▼ The impact of Hurricane Harvey has stressed the need for accurate flood
inundation forecasts to aid emergency response. The National Water Model uses predicted rainfall to produce forecasts of discharge and then generate flood
inundation maps. To confidently employ flood forecast models for future events, we first need to assess the accuracy of these flood maps. The National Water Model combined maximum river discharge values for the affected Texas region and Height Above the Nearest Drainage (HAND) to calculate the extent of
inundation from Hurricane Harvey. We compared this predicted
inundation extent with a database of over 2000 high water marks gathered by the U.S. Geological Survey. At each high water mark location we calculated the difference of
inundation depth between the National Water Model prediction and the measured high water mark. We find that the prediction has low bias with a mean difference of 26 cm, although there are far larger depth differences at individual locations. For approximately one-third of the comparisons made there is less than one meter of vertical difference between the National Water Model forecasted depths and the observed high water marks. We hypothesize that channel features such as slope, length, and stream level are factors which influence the accuracy of the forecasted
inundation depths, and present relationships found between these features and the accuracy of their forecasts. From this analysis, we find that the presence of pluvial flooding and storm surge is likely to obscure significant trends between these channel factors and prediction accuracy as the National Water Model models only fluvial flooding. We find that in regions where the model over-predicts inundated depth, slope and stream level are strong predictors of accuracy.

▼ Two kinds of tsunami models are used in this thesis to simulate tsunami propagation in the ocean. One is the linear dispersion tsunami model developed by Port and Airport Research Institute (PARI), Japan. The other is COrnell Multigrid COupled Tsunami model (COMCOT) developed by the School of Civil and Environmental Engineering, Cornell University, that carries on the tsunami run-up computation to the nearshore region. Two kinds of tsunami models have the same mechanism of initial wave profile, which is the vertical seabed displacement as the initial tsunami profile proposed by Mansinha and Smylie (1971). Both models describe the tsunami by the same shallow water equations. At first, the feasibility of the PARI model is established by comparing with the record in Maldives during the South Asia tsunami in December 2004. Then, the COMCOT model in applied to the Pingtong earthquake in December 2006 and is validated by comparing with the tidal station records.
Possible submarine fault activities around Taiwan and the Western Pacific ring is simulated by the The PARI model based on moment magnitude scale (ï¼w) close to the South Asia tsunami. Seven sources are chosen: the Hokkaido, the East Japan, the Ryukyu Islands, the Guishan Island in Taiwan, the Fukien of mainland China, the Luzon Island and the New Guinea. The results suggest the northeast and southwest part of Taiwan have potential tsunami risk.
Finally, we simulate the fault activity between Taiwan and Luzon islands by the COMCOT model. The
inundation area extends northward to the Tso-Ying and San-Min districts, eastward to the Siao-Gang district and Fengshan city. The Kaohsiung harbor can resist tsunami hazard for moment magnitude scale (ï¼w) up to 7.58 with maximum wave height of 5.5 meters.

▼ The absence of proper sanitation in urban slum areas in African mega cities is a multi-faceted problem where a socio-economic as well as a technical approach is required to come to a sustainable solution. Consequences of the lack of sanitation in slums can be the deterioration of groundwater and surface water quality by an increased input of nutrients such as nitrogen and phosphate species and an input of bacteria/viruses. Additionally the deterioration of surface water quality can lead to eutrophication. This research focused on the presence of nutrients in groundwater and the processes governing their fate. A monitoring network of 26 wells was installed in the Bwaise III slum area in the capital city of Uganda, Kampala. Water levels were registered weekly and slug tests were performed to determine the horizontal hydraulic conductivity. Parameters measured in the field on water samples were EC, pH, temperature, alkalinity, orthophosphate, nitrate and ammonium. In the laboratory, samples were analyzed for all cations and anions. Soil samples were analyzed for grain size and geo-available metals. Additionally, a phreeqc model was set up in order to validate the groundwater flow velocity and the possibilities for cation exchange occurring in the soil.
A NE-SW hydraulic gradient of approximately 3 m/km was derived from the groundwater level measurements with a hydraulic conductivity of 3.43 m/day. The groundwater flowing through the region ended up in Nsooba channel. Chemical analyses showed Bwaise acted as an effective nitrate reducing system where, in the southwestern parts, iron was also being reduced. Ammonium was well established in the region with values up to 1 mmol/l. Orthophosphate presence was 2-10 µmol/l in groundwater which was markedly less than the calculated input of 26.3 µmol/l. The geo-available metal content of the soil combined with the coarse grain sizes encountered showed that sorption to metal oxides is an unlikely mechanism for the marked decrease in orthophosphate. Mineral saturation indices revealed that hydroxyapatite could regulate orthophosphate concentrations in the nitrate reducing part of Bwaise and vivianite in the iron reducing part of Bwaise. The phreeqc model showed that different values for the assumed porosity and cation exchange capacity can produce the same pattern seen in the chloride and sodium values in the field.
Contrary to conclusions raised by other researches, our study showed that under the right circumstances, pit latrines as a means of managing waste in slum areas can be a favourable option from a nutrient management point of view especially in relationship to disposal of waste in drains that discharge in surface water.

▼ Decision support tools used in water resources management allow stakeholders to make informed decisions and assess the trade-offs of alternative management options. However, these tools are typically driven by the regulation of lakes and reservoirs and often do not fully incorporate the dynamics of wetlands. Wetlands provide important socio-economic and environmental services that should be protected and sustained. However, the cost associated with collecting enough in-situ data to accurately characterize the hydrology of many wetlands impedes their integration into hydrologic models. This study investigates how remotely sensed information (from satellites) can be leveraged to develop and calibrate hydrologic models of wetlands in data scarce areas. The value of this research is demonstrated for the Sudd Wetland, a vast seasonal wetland located in South Sudan that is a critical component of the Nile River hydrology. The Sudd hydrologic model was developed through an iterative approach where the complexity of the model was increased incrementally, following holistic comparisons between the model fluxes and states and the relationships between them. The wetland model was calibrated to the Sudd outflows and flooded area extents, using an objective function that measures how well the model can simulate these fluxes in terms of both magnitude and timing. The Sudd inflows and outflows were estimated from a combination of in-situ river flow data, satellite altimetry measurements, a hydrologic rainfall-runoff model, and multiple autoregressive river routing models. Monthly estimates of the Sudd flooded area extents were derived primarily from MODIS (MODerate Resolution Imaging Spectrometer) optical satellite imagery, using a new wetland land cover classification and
inundation mapping procedure that was developed in this research. The Sudd model also relied on gridded precipitation and evapotranspiration estimates. Multiple satellite-based data sources were leveraged to estimate these fluxes, and accuracy was assessed by how consistent the precipitation and evapotranspiration rates were with the overall Sudd water balance. Uncertainties ingrained in the model structure, calibration parameters, and satellite-derived hydrologic data were considered jointly when assessing model performance and introducing new processes and more complex relationships in subsequent model formulations. The final model can simulate the estimated outflows with sufficient accuracy (a Nash-Sutcliffe Efficiency coefficient of 0.75 was achieved); however, discrepancies remain between the simulated and MODIS-derived flooded area extents. Following a thorough analysis of the advancing and receding patterns of the
inundation maps, these discrepancies are believed to be related to the connectivity of the full flooded area extents to the main Sudd water body that regulates the outflows. Recommendations for future research are made that might improve the satellite-based wetland
inundation maps and hydrologic flux estimates, and the underlying structure of the…

▼ Globally, many large, lowland rivers are regulated due to the construction of stopbanks and flood protection schemes. Many of these changes now govern discharge regimes and lateral floodplain interactions. These modifications, along with others, contribute to declines in many native fish, including larval Galaxiidae of whitebait. Many attempts to enhance whitebait fisheries within New Zealand have focused on restoring spawning habitat. However, no research has been aimed at understanding the dietary requirements of riverine whitebait and where they source their food from during upstream migration. Previous work has hypothesised that receding floods may introduce large-bodied zooplankton, to the river which may be important for whitebait during upstream migration. The objectives of this research were to investigate (i) the potential of zooplankton to emerge from floodplain soils following
inundation, and (ii) whether certain zooplankton groups, indicative of those originating from floodplains, could be a food supply for migrating juvenile Galaxias maculatus in the lower Waikato River. Previous work investigating zooplankton communities in the lower Waikato River floodplain was undertaken during
inundation events, but, the origin of zooplankton could not be pin pointed.
To test whether inundated floodplain areas developed zooplankton from dormant states in soils, dry soil cores were collected from native forest, scrub (predominantly Salix sp.) and pasture vegetation types, inside and outside of stopbanks to provide different levels of connectivity. Zooplankton emerged from submerged soil within three days of wetting and after 12 days of
inundation no new taxa arose. Community composition differed between vegetation types, with larger-bodied cladocerans and copepods dominating native forested and scrub sites, and rotifers dominating pastoral sites. Connectivity did not play a statistically significant role in determining composition of zooplankton communities. Differences in zooplankton composition between sites indicate that floodplain vegetation structure has a dominant role in the development of communities of zooplankton during flooding. Differences in vegetation types were largely due to varying levels of soil moisture, canopy cover and other environmental factors.
Gut analyses indicated that juvenile G. maculatus feed on a wide range of aquatic and semi-aquatic organisms. Large-bodied zooplankton and insects found in the gut likely came from multiple sources. Insect presence varied over time whereas Cladocera dominance appeared to be related to flow pulses. Field diet analyses and laboratory selectivity experiments yielded similar results regarding selectivity. Feeding in the laboratory was density-dependent as more food items were consumed at lower fish densities, with no evidence of prey switching to less desirable groups at high densities.
This study has increased the understanding of potential food-web linkages between rivers and their floodplains for migrating whitebait populations. The findings of this…

▼ Piezometers were installed along Keewaydin Island (KI) at 55 loggerhead turtle (Caretta caretta) nests to determine water levels within the egg chamber during eight to twelve hour sampling periods and the water’s effect upon embryonic development. Hatching success was calculated by excavating nests and determining the relative proportion of hatched to unhatched eggs. For unhatched eggs, we reported the embryonic stage at which development ceased. In 2012 approximately 46% of the variance in hatch success on Keewaydin Island was due to the
inundation of nests. The hatching success of nests on Keewaydin decreased by 2.9% (s=13.5%) after one day of
inundation, 27.2% after two days of
inundation, and 77% (s= 16.8%) after three days of
inundation relative to the hatching success of nests that were never inundated (86.6%, s=8.5%). Patterns in nest placement on KI were documented using Geographic Information Systems. Greatest inundations appeared to occur in INBS sections N-4 and S-5. Future management plans need to consider the effects of
inundation on KI.

▼ A large part of the world population lives in deltas or in the vicinity of a river which provides many advantages, such as access to transportation, food and drinking water. Inundating floodplains are a natural and recurring phenomenon which is for instance a way to irrigate soils, but drawbacks occur when people or infrastructure are harmed by (extreme) inundations. Developing countries in Africa and Asia are the regions expected to experience the largest increase in impact of inundations in the coming decades. Conventional flood risk studies can effectively analyse (fluvial) inundations, but require considerable and sometimes complex data and software, which is not always available, in particular in the aforementioned regions in Africa and Asia. Additionally, these studies often rely on discharge data, which is not always available and becomes less accurate for extreme discharge when the river banks overflow. Furthermore, even when data is available, this might only be granted after long, bureaucratic procedures. Elevation data is available from publicly available models, but the horizontal and vertical resolution often does not suffice. Therefore, there is a need for an alternative method to analyse fluvial inundations that is more independent and uses open source data and software. Moreover this method needs to provide information on a high temporal resolution (daily) because of the dynamic behaviour of inundations. The spatial resolution should be as high as possible, given the limitations of temporal resolution. This research focuses on detecting, estimating and mapping inundations in the Ouémé delta (Benin, West-Africa) to retrieve information about extent and timing of inundations and analyse how inundations developed over time by means of satellite remote sensing imagery and open source data and software. Furthermore, it aims to investigate how upstream precipitation (causing fluvial inundations) and population in the Ouémé delta (subjected to the effects of inundations) developed over the past decades to make a first step towards analysing the impact of inundations. To answer the research questions an
Inundation Extent Mapping Model (IEMM) is developed to detect inundations, estimate the
inundation scale and subsequently allocate the estimated surface water fraction in an area of interest (the measurement cell). First an
inundation detection method is developed and tested (CMC-ratio), which relies on scaling a measurement cell between a (dry) calibration cell and an additional (wet) calibration cell. Second, the
inundation scale estimate of the CMC-ratio is validated with MODIS optical remote sensing imagery and improved by developing and testing various scale estimation methods. Third, the estimated scale is allocated by comparing different elevation maps (MERIT DEM and HAND) and mapping methods. The outcome of the IEMM is compared to discharge to obtain information about timing of inundations and confirms that the IEMM is increasingly sensitive to larger inundations whereas discharge measurements are…

▼ Sea level is rising across the UK and this is expected to accelerate and to increase coastal flood risk over the 21st century. Southampton is one of the busiest and most important national ports, but coastal flooding has not been studied extensively before. This dissertation aims to investigate the likelihood of coastal flooding in Southampton during the 21st century with and without the effect of sea-level rise using the ‘bath-tub’ and LISFLOOD-FP methods. Sensitivity of LISFLOOD-FP and discussion of datasets and methodology are performed to estimate uncertainty in LISFLOOD-FP simulations for Southampton. At present, flooding ‘hotspots’ are located in Priory Road, Millbank, the Cross-house area, Riverside Park, Woodmill Lane, Industrial Park (Bitterne Manor), Weston Shore and The Test Nature Reserve (commercial, industrial areas and open spaces). 1 in 250-year and 1 in 1000-year events could cause deep flooding on a small scale at Millbank, Weston Shore and Test Lane according to LISFLOOD-FP simulations. Under sea-level rise, extreme water levels will be higher and occur more frequently. For Southampton the return periods of extreme water levels may decrease by about ten times for a 0.2m rise in sea level. Future coastal floodplains significantly expand on the west side of the River under 0.4m sea-level rise, and in the Docks with 0.4-1.0m sea-level rise during 1 in 250 year event. A preliminary evaluation on the impact of flooding on coastal infrastructure is made. LISFLOOD-FP results for the 250-year event show approximately 500 and 1,000 buildings could be located in floodplains for 2010, and 0.2m sea-level rise, respectively. 12-13km of railways and 4-7km of A roads could be disrupted by 0.4-0.6m sea-level rise. Structural and non-structural solutions are also proposed for Southampton, including a tidal gate, water-proof technologies, flood forecasting and warning systems, etc. to adapt to coastal flooding over the 21st century.

▼ In this study, a probabilistic vulnerability assessment to the impact of storms in the coast of Thrace, Greece was carried out. To this end, the methodology presented by Bosom and Jiménez (2011) has been applied with some modifications. The introduced modifications, for this work, were the use of a different run-up model to deal with the uncertainty in the predicted magnitude (due to some reported under-prediction of run-up, using Stockdon et al. equation, 2006) observed in recent studies (Laudier et al. 2011). In addition, the vulnerability framework has been extended by including overtopping in order to characterize better the flooding hazard. For this project, the study area was the coast of Thrace, Greece and the used data were 3-h hindcasts of the WAM model for a time period of 10 years (January of 1995 – December of 2004) at fifteen stations of the N. Aegean Sea. Its variables were the significant wave height, Hs, the wave peak period Tp, the wave direction, Hdir. With this dataset, the return values of the hazards’ (i.e. inundation and erosion) for the return periods of 5, 10, 30 and 50 years were estimated, using the Reis and Stockdon equation to calculate the wave-induced run-up and the numerical model SBEACH to calculate the storm-induced erosion. Aim of these estimations was to compare the difference between each hazard magnitude with the corresponding geomorphologic parameter (i.e. beach height and width, respectively) in order to characterize the vulnerability of the coast against each hazard and for each return period. The obtained results along the coast reflect the relative variation of the hazard magnitude in function of the beach morphology, which is mild-sloped and low beaches presenting the largest values for inundation, while the steeper and narrower ones are the most sensitive to erosion. Finally, an integrated vulnerability assessment was presented and some possible recommendations to mitigate the problems were given. It must be stressed that coastal managers play an important role in the final assessment, since they must decide the probability of occurrence to be accepted as well as the period of concern of the analysis. These two variables will determine the return period to be considered for the decision-making.

▼ Flooding is the most threatening natural disaster worldwide considering the fatalities and property damage it causes. Recent flood disasters have raised concerns for accurate and responsive
inundation forecast due to the rapid spread and astonishing destructive power of these events. Although recent development in large scale hydrologic simulation has enabled the real-time streamflow simulation operating on millions of river reaches, a framework for converting the forecast discharge into corresponding water surface elevation and
inundation maps at a continental-scale is absent to better support local flood response. To accurately map flood
inundation extent, a comprehensive description of the geometry of the channel is indispensable. As such, this dissertation presents an innovative approach for estimating river geometry and conducting
inundation mapping at a continental-scale with a high spatial resolution. This approach is based on the concept of Height Above Nearest Drainage (HAND). Advanced hydrologic terrain analysis workflows have been designed to derive channel hydraulic properties, stage-discharge rating curves, and
inundation extents using HAND. After the mechanism being presented, the implementation of this approach across the contiguous United States has been demonstrated using the 10-meter National Elevation Dataset. The integrity of the outputs has been validated through the comparison with best available references at multiple test sites. Considering the increasingly availability of high-resolution topographic data derived from lidar technology, the dissertation further presents how advanced geomorphic feature extraction tools are integrated into the proposed approach to overcome the challenges associated with the enrichment of terrain details. At last, this dissertation presents how banklines, an essential piece of river geometry characteristic as the boundary differentiates channel zone from floodplain, is detected with enhanced geomorphic feature extraction tools for improving large-scale hydrologic simulation and
inundation mapping accuracy.

inundation and precipitation over small (< 4 m) elevation gradients was examined by measuring interannual growth increments of boles and knees at five sites at Sardis Lake, Mississippi. There was a significant (p=0.019) growth response to precipitation during November to April (the wet season), but there was not a significant growth response to
inundation during the growing season (May to October). Because lake level at Sardis is controlled by the Army Corps of Engineers for flood control, the Sardis Lake shoreline area may be a habitat where growth response to precipitation and
inundation differs from systems where precipitation and
inundation are linked. The growth of knees from bald cypress roots was compared to growth of the boles in order to determine if knees and boles respond to the same environmental factors. It was found that the knees have high positive correlation coefficients when compared to the tree's bole if we assume that knee growth is initiated in response to a major flood event. If we assume knees grow in response to stress that limits bole growth, we would expect but do not find any discernable relationship between the initiation of knee growth and the timing of flood events.

▼ Sustainable floodplain management is essential in achieving a balance between population growth and natural resource protection, especially in the face of climate change. While floodplain development in the Middle Rio Grande Valley has allowed for economic expansion in the region, it has come at a cost to the fragile ecosystem of the Southwest. In this study, the historical Albuquerque reach of the Middle Rio Grande is reconstructed, including floodplain topography, channel characteristics, and land cover from approximately 1918. The impacts of river engineering on flooding events are evaluated by comparing historic and current conditions. Hydrodynamic modeling is first used to quantify the effects, then results are analyzed by calculating inundated area and visualized with
inundation mapping. Model results show a decrease in inundated area, accompanied by a rise in flood stage. This has implications for both sides of the human-environment interface and identifies the need for rebuilding system resiliency and restoring connectivity.

▼ Hydrologic and hydraulic modeling are used to assess watershed function at different spatial and temporal scales. Many tools have been developed to make these types of models more accessible to use and model results easier to interpret. One tool that makes hydrologic models more accessible in a geographic information system (GIS) is the Automated Geospatial Watershed Assessment tool (AGWA); the GIS enables the development of spatially variable model inputs and model results for a variety of applications. Two major applications of AGWA are for rangeland watershed assessments and post-wildfire rapid watershed assessments. Each of these applications have primarily utilized the Kinematic Runoff and Erosion model (KINEROS2) which is accessible in AGWA. Two new tools were developed which work within the existing AGWA/KINEROS2 framework in ArcGIS to enhance rangeland and post-wildfire watershed assessments. The Storage Characterization Tool, was developed to work with high-resolution topographic data to characterize existing stock ponds so these features can easily be incorporated into AGWA/KINEROS2 for rangeland hydrologic analysis. The second tool simulates reach scale flood
inundation (the
Inundation Tool) utilizing AGWA/KINEROS2 outputs and local channel properties for Hydrologic Engineering Center (HEC-2) hydraulic calculations to compute flood
inundation in post-wildfire environments. Both tools have been validated using multiple datasets and desired applications were outlined so that the tools are properly used.

▼ The global climate is changing and much of this is attributed to the greenhouse effect, which has been exacerbated by increased anthropogenic releases of greenhouse gases (GHGs). However, important GHGs, carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4), are produced naturally in the soil during the metabolism of many soil microbial and plant communities. The generation rate of GHGs depends on many factors, including soil community composition, nutrient availability, temperature, and soil moisture. Predicted climate variability is expected to alter temperature and rainfall patterns, which can impact the factors regulating natural generation of GHGs. With changing fluxes of GHGs, the natural feedback loops between GHG generation and climate may change. Increased emissions from natural sources would exacerbate climate change, whereas decreased emissions may mitigate its impacts. Floodplains may be particularly susceptible to climate change, as their biogeochemical processing is driven by hydrology. For this study, ten mesocosms were installed on the floodplain of Stroubles Creek in southwest Virginia. A flood event was simulated in half of these mesocosms in both early spring and mid-summer, which represent extremes in soil moisture and primary productivity on the floodplain. Headspace gases were monitored for CO, N2O, and CH4. Efflux of CO2 and N2O was higher in summer than spring, and also increased following wetting events. Methane production was greater in the spring, with no detectable change with wetting. Increases in summer rainfall events could increase the release of important GHGs to the atmosphere, potentially at levels significant to climate change.

▼ A flood
inundation study is presented for a watershed located in south central Virginia. A HEC-RAS hydrodynamic model of the main river network was developed to assess the impact of a number of hydrologic events, including the Probable Maximum Flood (PMF), in the area of interest. The primary goal of the study was to transform discharge hydrographs produced by HEC-HMS, an event-based hydrologic model, into water surface elevations and flood
inundation spatial extents. Initially, a river terrain model was constructed using data from publically available sources and filed survey campaigns. HEC-GeoRAS and ArcGIS were used to document and integrate the considerable amount of data required for building the model. Then, a calibration process was performed using stage-discharge predictor curves. The HEC-RAS unsteady flow component was employed for routing the discharge hydrographs through the modeled river network. Flood
inundation maps, as well as longitudinal water surface elevation and channel velocity profiles were generated for the study reaches. As part of the flood
inundation study, an uncertainty quantification analysis was carried out on the boundary roughness of the floodplains. The objective was to measure the extent to which flood inundated areas, water surface elevations, and channel velocities were influenced by variations on this empirically-based model coefficient. Finally, the impact of various hydraulic characteristics of the modeled river on the sediment transport process is examined. This characterization is intended to provide a better understanding of a subsequent sediment transport modeling effort to be performed under severe flooding conditions.

▼ We conducted a study to address uncertainties associated with the metabolism and net carbon fluxes for the tidal wetland and estuarine portion of the coastal ocean because of these zones disproportionately large role in ocean carbon
dynamics. We measured open water diurnal O2 and CO2 dynamics seasonally in the Duplin River salt marsh-estuary in Georgia, USA with a particular focus on the marsh-estuary linkage associated with tidal flooding. We observed that the overall system was a
net source of CO2 to the atmosphere and adjacent coastal ocean and a net sink for oceanic and atmospheric O2. Rates of metabolism were extremely high, with respiration (R: 43 mol/m2/yr) exceeding gross primary production (GPP: 28 mol/m2/yr). Rates of
metabolism measured with CO2 were substantially higher than with O2. The net heterotrophy of the aquatic salt marsh-estuary system is supported primarily by the net production of the salt marsh proper.

▼ The Himalayas of South Asia are home to many glaciers, which are retreating because of climate change and leaving in their wakes large lakes. These lakes are held in place by naturally deposited and inherently unstable moraine dams, which are at risk of overtop by impulse waves, commonly generated when avalanches or landslides enter the lake. When an overtopping event causes catastrophic failure, a glacial lake outburst flood (GLOF) occurs. The Imja glacier is experiencing the highest mass loss rate in the Mount Everest region, contributing to the expansion of Imja Tsho, a lake with several villages downstream. A GLOF from the lake can bring catastrophic damage to these villages, threatening both property and human life and creating a need to understand the processes that trigger these floods. The process chain for an avalanche-induced GLOF was modeled numerically, using the output of one subprocess as input into the next. First, the volume and momentum of various avalanches entering the lake were calculated using RAMMS. Next, the subsequent waves were simulated using BASEMENT software and validated with empirical equations to ensure the proper transfer of momentum from the avalanche to the lake. BASEMENT was then used to model moraine erosion and downstream flooding, which yielded a map of risk areas downstream. Moraine erosion was calculated for two geomorphologic scenarios: a site-specific scenario using field data, and a worst-case scenario based on past literature and applicable to lakes in the entire region. Neither case resulted in flooding outside the river channel at downstream villages. The worst-case scenario resulted in some moraine erosion and increased channelization of the lake outlet, which yielded greater discharge downstream but no catastrophic collapse. The site-specific scenario generated similar results, but with very little erosion and a smaller downstream discharge. Results indicated that Imja Tsho is unlikely to produce a catastrophic GLOF in the near future; however, some risk exists within the river channel, necessitating continued monitoring of the lake. Furthermore, these models were designed for ease and flexibility so that they can be adopted by a wide range of stakeholders and appropriated for other lakes in the region.

▼ Floodplain
inundation often provides water quality benefits by trapping sediment and biogeochemically transforming other pollutants. Hydrologic floodplain connectivity is a measure of water exchanges and interactions between the main channel and the floodplain via surface (
inundation) and subsurface (groundwater) connections. Using an automated model combining GIS and numerical analysis software, this study examined floodplain
inundation patterns and measured floodplain connectivity for the Mahantango Creek watershed (Pennsylvania, USA). Connectivity was quantified by developing a metric that included
inundation area and duration. Long-term hydrographs at each reach in the watershed were developed via QPPQ (Flow-Percentile-Percentile-Flow) methodology using regional regression analysis to calculate the ungauged flow duration curves (FDC).
Inundation area (normalized to stream length) was found to increase with drainage area, suggesting larger streams have more area available for biogeochemical activity. Annual connectivity increased with drainage area, suggesting larger streams, having higher connectivity, should be the focus of individual reach restoration projects due to higher potential for water quality benefits. Across the watershed as a whole, however, the total annual connectivity across first order streams was greater than higher order streams, suggesting the collection of small streams in a watershed may have a stronger effect on outlet water quality. Connectivity was consistently higher during the non-growing season, which was attributed to higher flows. Despite higher connectivity during the non-growing season, increased floodplain biological activity may be negated by low temperatures, reducing microbial activity. Correlations between land use and connectivity were also found, emphasizing dynamics between flow, channel morphology, and floodplain
inundation.

▼ Freshwater is one of the world’s most important natural resources. It is essential to human health, ecosystem function, and livelihoods, but is a finite resource and needs to be appropriately managed. As global demand grows, there is increasing competition for resources between the water, agriculture, energy, livestock, fisheries, forestry, mining, transport, and other sectors. Conceptual frameworks for water policy such as integrated water resources management and the water-energy-food nexus have emerged to balance these competing interests. However, the policy challenges to meeting societal demands for water while maintaining ecosystem function are exasperated by the modification of water availability due to changing land use and climate conditions. Reliable methods to monitor and predict water availability are essential for understanding the vulnerability of water resources to future changes in land use, climate, and policy. The overarching objective of this dissertation is to better understand how changing patterns of land use and climate conditions impact the distribution and availability of freshwater resources. This dissertation first examines the impact of the current mountain pine beetle (MPB, Dendroctonus ponderosae) outbreak in the western United States (US) on surface water resources. In the Western US, the current MPB epidemic has affected more than five million hectares since its start in 1996, including headwater catchments that supply water to much of the Western US. There is widespread concern that the hydrologic consequences of the extensive pine tree die-off will impact water supply across the Western US. While forest disturbance studies have shown that streamflow increases in response to tree harvest, the actual effect of bark beetle infestations on water supply remains widely debated among MPB researchers. This study evaluates watershed-level response following bark beetle outbreak for 33 watersheds in seven western states. Streamflow records were investigated to assess whether the timing and amount of stream discharge during bark beetle outbreak and early recovery periods were significantly different to pre-outbreak conditions. Results show no significant modification in peak flows or average daily streamflow following bark beetle infestation and that climate variability may be a stronger driver of streamflow patterns and snowmelt timing than chronic forest disturbance. The second part of this dissertation examines how surface water resources in the Awash River Basin, in Ethiopia, were impacted by the 2015 regional drought and their subsequent recovery. This study presents a new method to develop accurate, high-resolution maps of waterbodies. Cloud-based computing resources and machine learning techniques are used to merge Sentinel 1 synthetic aperture radar (SAR) and Landsat observations to generate monthly waterbody maps at a 10-meter resolution. The accuracy of this method is shown to be comparable to waterbody map products generated by high performance computing resources. The technique is…
