▼ Sedimentation is one of the problems that affects the storage capacity of most small reservoirs, and if not addressed on time, may lead to the dams being filled up with sediment and failing to meet the intended objective of providing agricultural water for food and economic security. The aim of this study was to assess the effects of sedimentation on the storage capacity losses of Moffat dam and GRZ weir located in the Mushibemba catchment of the Mkushi Farm Block in Central Province, Zambia. The Mushibemba catchment has the highest number of reservoirs that were constructed to meet increased irrigation water demands. However, there is lack of application of the knowledge on appropriate techniques of assessing sedimentation rates on reservoirs in the catchment. Understanding the nature of sedimentation in the Mushibemba river catchment is useful for mitigating against the reservoirs being filled up with sediment. The specific objectives of this study were to (i) determine the storage capacities of two reservoirs; (ii) estimate suspended sediment transport into the streams draining reservoirs and; (iii) determine the rates of sedimentation on the Mushibemba reservoirs. Bathymetric survey using hydrographic boat mounted with a differential GPS was used to collect reservoir depths, water surface elevation and reservoir perimeter. For water quality assessment, water samples were collected at the intake of each reservoir and analysed for concentration of total suspended and total dissolved solids. The results of the study revealed that the measured volumes of Moffat dam and GRZ weir were 1,180,462 m3 and 197,218 m3, respectively. The measured reservoir capacity values were then compared with the originally calculated designed capacity values to determine changes in storage capacity over the years. The storage capacity losses for Moffat reservoir was found to be 223,789 m3 (16 percent) whereas that of the GRZ Weir was 53,312m3 (21.3 percent). The estimated rate of sedimentation loss for Moffat reservoir was found to be 13,986.81 m3 yr-1 with a lifespan of 84 years while that of GRZ weir was 1,480.89 m3 yr-1 with a lifespan of 133 years. The sediment concentration inflows inflow into the Moffat reservoir and GRZ weir were in the same low order of magnitude, 0.6 mg/l and 0.4 mg/l respectively. The source of the suspended sediment was mainly attributed to the cleared commercial agricultural land which predominantly consists of clayey to loamy soils in the vegetated catchments. This also accounted for the high turbidity of the reservoir water. It is concluded that sedimentation in the catchment is fairly low but serious given reservoir capacity losses observed due to agricultural activities despite having a good vegetation cover. Soil conservation measures are needed to avoid degradation of the catchment in future. Keywords: Sedimentation, Bathymetry survey, Reservoir storage capacity, Suspended sediment, Central Zambia

▼ The Tauranga Harbour is a mesotidal lagoon that is actively infilling with sediment. The southern basin of the harbour is important from both ecological and socio-economic standpoints. An understanding of sediment dynamics is necessary for the management of the harbour. Previously, the Tauranga Harbour Sediment Study (THSS) analysed the terrigenous flux of sediments into the harbour. It identified predominantly silt-sized sediment yields, from catchments, which remains confined to entry points into the harbour, or get exported out to the open coast. However, mapping of the tidal inlet and parts of the Western Channel through to Rangiwaea Island, has identified that accretion involves sand-sized sediment. The presence of eroding cliffs has provided speculation that sediment is primarily derived by local source erosion, as opposed to terrestrial or marine inputs. However, little is known about the sediment dynamics through the central harbour region. This thesis involved seismic reflection surveying through the Western Channel, from Rangiwaea Island to Matakana Point, utilising a Knudsen Sub-Bottom Profiler that operates on a chirp sonar system. Through the seismic analysis, patterns of sandwave occurrence were analysed to discover how sediment dynamics varied along the Western Channel. Additionally, three fault sites were identified in the seismic profiles. Two of these faults occur parallel to a previously mapped fault at Omokoroa, where doming has been suggested. The third fault occurs in the southeast where subsidence has been identified. Vibracoring was utilised to collect intact, contiguous, and undisturbed cores through the field area. Sand is identified as the primary contribution to ongoing sedimentation in the harbour. A general coarsening trend of sedimentary texture is observed from the central intertidal flats through the upper Western Channel towards the tidal inlet. This pattern is disrupted where current amplification or close proximity to a sediment source is associated with the accretion of coarser sediment to form sandwaves. Rates of sedimentation through the Western Channel over the last 7,200 years, ranged from 0.0482 mm/yr approaching the tidal flats, to 0.436 mm/yr where extensive sandwave were identified. A sedimentation rate of 0.0977 mm/yr was calculated within the channel where no sandwaves were present. The primary source of sediment appears to be local erosion of coastal cliffs, with sedimentation rates strongly correlating to erosional sites.

Despite the many positive effects of dams, they can also have several negative impacts on natural systems. One of these impacts is the decrease in sediment inflow towards the coast which can lead to coastal erosion. A technique that can be applied to improve the situation downstream is modifying the discharge through the dam. Unfortunately, there have not been many studies done yet on such a re-operation regime. This thesis tried to get more understanding of the possible consequences of a modified discharge regime concerning restoration of pre-dam sediment regimes based on the Volta Delta in Ghana as a case study. In this thesis, the effect of modifying dam operations on both the upstream part of the river (the reservoir) and the downstream part have been investigated. For the upstream section, a simulation was made for a simplified model for a reservoir with similar characteristics as the Volta Lake. According to this model, the modified dam operations are not useful for reservoirs like the Volta Lake. The technique might be useful for shallower reservoirs. A modified dam operation scenario aims to reintroduce flood pulses to the river. For the downstream part of the river, three aspects of the operation scenarios have been investigated: the discharge peak height during an operation, the duration of such a peak and the extra sediment load that might be brought to the river from the reservoir. The response of the river downstream was measured by two aspects: the sediment load to the ocean and the bed level changes in the river. To show the response of the river, several simulations were made with different aspects of the operation scenario. At each simulation, only one parameter was changed, e.g., the peak discharge is changed from 1500 to 5000 m3/s in different simulations. By doing so, graphs could be made to show a correlation between the three operation aspects and the two aspects of the river's behavior. It turns out that by increasing the discharge, more sediment will be transported to the ocean (with a maximum of 16% of pre-dam sediment load). There will be more non-cohesive material carried to the sea than cohesive material. When there is no extra sediment coming to the river, the river bed will degrade. This will happen at equal rates all along the river which will not change the bed slope. By increasing the sediment load from upstream of the dam without introducing flood pulses, there will be more sediment transported to the ocean. However, most of the sediment will settle at the river bed causing accretion. The accretion of the river bed will not happen at equal rates along the river so the bed slope will change. Finally, the change in peak duration will affect neither the transport of sediment nor the river bed. The reason for this might be that the river bed adapts to the different flow conditions in such a way that the same amount of sediments is transported towards the coast.

▼ Large volumes of aeolian sand and dust are deflated from unconsolidated till deposits, and supraglacial debris surrounding McMurdo Sound, Antarctica. This material is transported offshore with windblown snow onto extensive winter-formed sea ice in the southwest Ross Sea, and is subsequently released into the water-column during summer sea ice breakup. Aeolian sediment samples were collected from a ~600 km² area of sea ice in western McMurdo Sound to determine the magnitude of deposition and identify sediment sources. A new 2-dimensional numerical aeolian sediment transport model (NaMASTE) tuned specifically for the McMurdo Sound area, was used to explore the ability of the local wind system to move sediment from source areas to sea ice and to determine the pattern and extent of aeolian sediment dispersal to the southwest Ross Sea. Debris deposits on the McMurdo Ice Shelf debris bands are the most dominant sediment source for the area. Unconsolidated deposits between Cape Bernacchi and Spike Cape, and the Taylor Valley mouth are significant secondary deposits. Mass accumulation rates varied between 0.15 g m⁻² y⁻¹ and 54.6 g m⁻² y⁻¹, equating to a background aeolian sediment accumulation rate, excluding extremely high values, of 1.14 ± 0.59 g m⁻² y⁻¹ for the McMurdo Sound coastal sea ice zone. This is 3–5 orders of magnitude more than global background dust fallout for the Ross Sea. Modal grain size is very-fine sand to coarse silt. Notably, much of this material is distributed in localised, high sand content plumes that are oriented downwind from source, with finer deposits found outside these zones. An average seafloor linear sedimentation rate of 0.2 cm ky⁻¹ is calculated for McMurdo Sound, which is minor compared to biogenic sedimentation for the region. This equates to ~0.7 Gg y⁻¹ aeolian sediment entering McMurdo Sound during sea ice melt. Application of NaMASTE successfully simulated the general aeolian sediment distribution pattern. Testing of model variables suggests that aeolian material is mainly transported during strong (>20 m s⁻¹) wind events. Modelling also suggests aeolian material from McMurdo Sound can be transported north to the Drygalski Ice Tongue, ~250 km from source, but only in very trace quantities.

▼ This ecological and geomorphological assessment of Horokiri Stream and Ration Creek was conducted across four longitudinal zones to explore the effects of sediment delivery, run-off, channel form, riparian and in-stream habitat. The Horokiri Stream channel has moved approximately 7 metres westward over the last 20 years, with both banks now covered in long grass, flaxes, natives with a mix of tall canopy trees. Looking at stream, Spearman’s for Ration at Figure 27 (n = 16, rho -0.243, p = 0.36) as deposited sediment increased, MCI decreased, non-significant. Spearman’s for Horokiri at Figure 28 (n = 16, rho 0.247, p = 0.35) as MCI increased with sediment, non-significant. Results from upstream of the riparian zones showed more deposited fine sediment. However, within both the riparian zones the sediment deposition was much lower. The native riparian planting along the stream banks had a positive effect on reducing sedimentation. The findings support the concept that the restoration of riparian zones with buffer widths exceeding 10 metres can improve stream habitat and invertebrate health. There was no relationship between flow and deposition rate P(X2>241.84) = 0.24. Figure 24 shows deposited sediment on MCI depending on land use groups (X2 = 11.81, df = 4, p = 0.019). No statistically significant differences were found (comparing the effect of sediment between different land use management groups). An experiment investigated a disturbance hypothesis in both Ration Creek and Horokiri Stream was conducted during February 2019. The experiment was designed to be long enough to study the effects of four weekly pulse flushing events created by scrapping the stream bed with a drain drag tool and the effects of a press sustained disturbance on the macroinvertebrate community. I measured the sediment and the macroinvertebrate captured in each trap within the experiment site every seven days. My prediction was that macroinvertebrate communities subject to sustained fine sediment delivery (press disturbance) are affected by simulated pulse flushing events (pulse disturbance). A comparison of sediment depositional rate before and after the manipulative experiment (Figure 36) showed higher sediment deposition after the pulse flushing events (1.55 W/A/D) compared to before during the assessment phase (0.88 W/A/D) in Horokiri (t = 2.35, df = 8.95, p = 0.04), but no significant difference before (1.57 W/A/D) or after (1.38 W/A/D) in Ration (t = -0.818, df = 7.71, p = 0.44). It appeared that the smaller riparian buffer width of 2-5m at Ration Creek did not limit sediment deposition. The effects of sediment disturbance in the experiment reflect the rapid ability of macroinvertebrates to respond to sediment by drifting out of unsuitable areas. The weekly pulse disturbance events resulted in increased sediment deposition compared to the background levels of sediment deposition (indicative of a press disturbance) in both streams. As pulse disturbance events increased, the number of macroinvertebrate taxa decreased. Horokiri Stream… Advisors/Committee Members: Renwick, James, Joy, Mike, Clapcott, Joanne.

▼ In Zambia, the need to conserve water resources through technologies that can easily be managed by the local communities has resulted in the construction of small dams. However, small dams are adversely impacted by sedimentation due to soil erosion in the catchment area. The aim of this study was to assess the water storage capacity loss for the selected small dams due to sedimentation in Lusaka Province. The studied small dams were; Lwiimba, Silverest, Morester and Katondwe dam. Data was collected by bathymetric survey for each small dam using hydrographic boat with echo sounding. The shape and area of each reservoir were determined by mapping reservoir perimeter with a boat equipped with DGPS, by taking several position points along the shore line. The initial storage capacity data were collected from the dam owners and through interviews with three key informants on the effects of sedimentation on dam uses and on the existence of sediment control measures. Analysis of data involved determination of reservoir surface area and storage capacities using the Area and Volume tool under ArcGIS 3-D Spatial Analyst. The deposited sediment volume was estimated by subtracting the measured storage capacities from the initial storage capacities of reservoirs. Thematic analysis was applied in analysing the effects of sedimentation on dam uses and the existence of sediment control measures. Results of the study revealed that the measured reservoir storage capacities for Lwiimba, Silverest, Morester and Katondwe dams were 101,051.43 m3, 368,331.5 m3, 14,724.32 m3 and 10,714.88 m3, respectively. The estimated sediment volumes equivalent to storage capacity loss for each dam were; Lwiimba (99,044.57 m3), Silverest (379,480.5 m3), Morester (13,805.68 m3) and Katondwe dam with 9,937.12 m3.The accumulation of these sediment volumes have led to capacity losses, drying of reservoirs especially in the dry season and reduced life spans of the dams. The estimated rates of sedimentation for Silverest dam was found to be 14,595.40 m3yr-1. At this rate, the reservoir lifespan was 26 years; Lwiimba (2,200.99 m3yr-1), with the lifespan of 46 years; Katondwe (283.92 m3yr-1), 38 years, and for Morester dam the rate was 251.01 m3yr-1 giving a lifespan of about 58 years. Natural vegetation cover was found to be the main sediment control measure used in the catchments to reduce sediment deposition by runoff. It is concluded that the studied small dams are seriously affected by high rates of sedimentation from the time of their construction. This calls for periodic dredging of deposited sediment in small dams in order to increase reservoir storage capacity for sustainable use of the water resources. More sedimentation studies need to be conducted in Zambia.

▼ The Carnegie Ridge is an aseismic ridge that bounds the south flank of the Panama Basin. Dynamic sedimentation around Carnegie Ridge is shown by evidence of erosion, dissolution and re-deposition of pelagic sediments where erosive episodes have carved out relict landscapes. I examine three aspects of these features: 1) What are the mechanisms involved in the erosive episodes; 2) Can the ages of the erosive events be constrained; and finally 3) Can the transport mechanism be identified? The extent of erosion and re-deposition was studied during the R/V Melville cruise MV1014 from October to November 2010 to compare with geochemical estimates of sediment focusing. The MV1014 cruise acquired geochemical, geological and geophysical data to compare with earlier surveys and scientific drilling. Large-scale erosion, presumably driven by massive, density-driven deepwater spillover events from the Peru Basin, created a prominent valley named Sand Dune Valley in the study area. A second, smaller valley, known as Western Valley, was likely formed by medium-scale erosion catalyzed by a ridge jump with subsequent normal faulting forming a fault scarp which has intensified near-bottom currents. Smaller-scale erosional events created small-scale surface sediment truncation. Utilizing a seismic stratigraphy developed by comparing seismic horizons to the sediment columns at DSDP Site 157 and ODP Site 846, and exposure of diagenetic chalk along the valley floors allowed a reconstruction of the timing of these highly erosive episodes. Two major erosive episodes are proposed to have occurred at ~5 Ma and ~3Ma which removed as much as 75 km3 of sediment. The erosive episodes may be linked to a ridge jump of the Galapagos hotspot at ~5-4 Ma and the final closing of the Isthmus of Panama ~3Ma. Sediment transport regimes for the Quaternary were determined using horizons dated at 2 Ma (PL-2), 1.7 Ma (PL-1) and 84 ka (Q-84). Isopachs created using the three horizons concluded that the dominant transport regime occurs to the NW of the study area with strong lateral transport to the sides of the valleys.

▼ Cultural eutrophication is caused by the excess addition of phosphorus to aquatic ecosystems, and has long been a water quality management issue in Lake Erie. Despite successful reductions in external loading of phosphorus in Lake Erie the in lake total phosphorus (TP) concentrations are increasing recently and symptoms of eutrophication are apparent. In this study I examined the sedimentation velocity of particulate phosphorus and how it is affected by stratification and plankton community composition over the growing season. Diatoms had the highest sedimentation velocities and a shift to slower settling species with greater form resistance (Synedra sp. and Fragilaria sp.) was observed during the stratified period possibly in response to the shallower mixed layer. No significant variation in sedimentation velocity was found with trap depth, plankton size or temperature; hence the individual plankton cells were employing methods to change their sedimentation velocity in accordance with changing environmental conditions. Phosphorus sedimentation was most closely related to silica sedimentation, which largely represents the sedimentation of the diatoms. Thus any shifts in community composition will affect phosphorus-settling rates. The sedimentation rate of phosphorus decreased from June 2nd until August 26th during the stratified period at station84 and from June 2nd to August 5th at station 452. The decline of total phosphorus was less than the sedimentation rate, hence, sediment resuspension and redistribution from the littoral sediments along with atmospheric deposition are important sources of phosphorus to the central and eastern basins of Lake Erie. The sedimentation rates of P, N and C did not follow the Redfield ratio. The sedimentation velocity of P was much less than that of C and N, indicating that P is conserved in the epilimnion and possibly that C and sedimentation contains more non-living material. Therefore, modelling phosphorus sedimentation after carbon and nitrogen sedimentation is inappropriate. Laboratory sedimentation towers can be used to measure phytoplankton sedimentation velocity including net upward movement, which traditional sedimentation traps are unable to do. Determination of the sedimentation velocity of the phytoplankton community to variables such as light, temperature and nutrient status, using this method, may eventually lead to a dynamic phosphorus model that could more effectively reduce eutrophication effects in Lake Erie.

▼ Eutrophication is the enrichment of water body by nutrients; especially nitrates and phosphates. These nutrients are used by phytoplankton such as algae and Cyanobacteria. High nutrient concentration cause algal bloom; if this is Cyanobacteria; it creates a big health problem to human and cattle depending on drinking water reservoirs by releasing toxic substance. This study investigates and quantifies the nutrients at Dire reservoir so that it is easy to identify the potential source of nutrients to the Dire reservoir which was constructed by Addis Ababa Water and Sewerage Authority for drinking water supply. Furthermore, the trophic status of the reservoir was identified in comparison to the amount of Chlorophyll-a. In doing so, Reconnaissance survey was made through systematic stratified sampling design where the soil, sediment and water in and around the reservoir and the tributaries flowing to the reservoir were sampled and analyzed in the laboratory for their nitrate and phosphate contents. A total of 22 waters, soil and sediment samples were taken for each of the sample types namely: water, sediment and soil in December and February, dry season. These were one from upstream and another from downstream of the tributaries flowing towards the reservoir such as Legedadi, Silmicha and Berek. In addition, five soil, five sediment and five water samples were taken inside and around the reservoir independently for the two months. The data obtained are tabulated to be analyzed using Microsoft Excel and SPSS software. Accordingly, analysis of variance and correlation of the parameters are evaluated. There is high nutrient deposition in the sediment compared to the soil and water; it is more concentrated at the downstream than the upstream of the tributaries which are an indication of erosion of upstream soil during the rainy season and aggravated by crop cultivation in the watershed. Surprisingly, the chlorophyll- a concentration (0.35μg/l) is not as much as the nutrients due to low light penetration. The reservoir is phosphorus limited and is hyper- eutrophic. The nutrients in the reservoir are mostly contributed by sediments of Legedadi (18.6mg/kg) and Silmicha (34.9mg/kg) Rivers. Hence, IWM must be applied by the stake holders paying attention to Silmicha followed by Legedadi and Berek tributaries. Advisors/Committee Members: Mekuria Argaw(Dr.) (advisor).

▼ The mangrove Avicennia marina var. australasica is rapidly colonising intertidal sandflats within a number of estuaries of the North Island of New Zealand. Many local residents perceive this change to be detrimental to the ecology and aesthetics of their estuaries, yet little empirical data is available to support these perceptions. Coastal managers are presently developing management strategies associated with either the maintenance or the removal of mangrove habitat with limited information available to predict the impacts of either course of action. This study was developed to investigate the physiognomic characteristics of the mangrove stands, and the physical and ecological impacts of their expansion within three embayments of Tauranga Habour: Welcome Bay, Waikareao Estuary and Waikaraka Estuary. Removal of mangrove vegetation within Waikaraka Estuary provided an ideal site to assess the physical changes that occur in response to this activity. Detailed field measurements of plant physiognomy of the mangroves within Welcome Bay, Waikareao Estuary and Waikaraka Estuary identified a limited vertical growth of < 10 cm per year, resulting in mean plant heights < 1.5 m. The climatic conditions limiting plant growth appeared to also limit the development of below-ground biomass (root mass). The 2 to 4 kg per m-2 of mangrove biomass under mangroves within Waikaraka Estuary is one of the lowest reported to date. Some mangrove sites within Tauranga Harbour produced pneumatophores at densities of ~ 700 m-2. This high density of pneumatophores increases the structural complexity of the substrate which was found to dampen the strength of tidal currents, in turn promoting sedimentation and limiting sediment re-suspension. The morphological reflection of this process was measured using Rod Surface Elevation Tables (RSETs), buried base plates, erosion pins and sediment traps. Typically surface sediments within mangrove colonies were mud-dominated, and sedimentation provided substrate accretion up to 21 mm yr-1 in the upper reaches of the study sites. Substrate accretion was also observed on un-vegetated sandflats in some upper-estuary and mid-estuary locations which may promote continued mangrove colonisation by elevating topography relative to the lower elevation limits for seedling survival of between 0.0 and 0.3 m MSL. A perception that mangrove colonisation has displaced bivalve populations was disproved in this study, at least within the upper estuary environments. A similar suite of benthic macro-invertebrates were encountered within both the mangrove and the un-vegetated tidal flat habitats. These benthic communities were dominated by deposit-feeding organisms such as polychaetes, and an absence of bivalves was common across both habitats. Approximately one hectare of above-ground mangrove vegetation (10% of the total coverage) was removed from Waikaraka Estuary between 2005 and 2007, which resulted in a lowering of the surface topography at average rates of 15 to 17 mm yr-1. Some textural change of the surface… Advisors/Committee Members: Healy, Terry R (advisor).

▼ There are many small dams in Zambia constructed for the purpose of collecting and storing runoff from the catchments. The flow of water into dams is accompanied with sediment resulting from soil erosion within reservoir catchments. The deposition of sediment in reservoirs has implications for their sustainability and thus future water supplies. However, accumulated sediment in reservoirs can be dredged to extend the useful lives of dams. This study aimed at evaluating the burden of sediment and sedimentation in selected small dams in Lusaka and Southern provinces of Zambia. A survey research design was employed to gather data from the sampled dams in Lusaka and Southern provinces of Zambia. A cost-benefit analysis was performed to determine the cost and value of burden of sediment and sedimentation on selected six small dams. A Contingent Valuation of Willingness to Pay was conducted to find out the possibility of local peoples’ support of a possible programme of dredging the accumulated sediment in the reservoirs to restore the lost storage capacities. of the dams. The results of the study showed a clear scenario of the burden of sediment to local communities and the potential restoration of lost reservoir storage capacities to sedimentation. The study established that 25 - 52 percent of studied reservoirs initial water holding capacities had been lost to sediment accumulation in 26 – 60 years of dam operations. The rates of sediment accumulation ranged from 283.92 m3 yr-1 to 29,118.63 m3yr-1, indicating that the surveyed reservoirs had less than 60 years of useful lives beyond the year 2015. Sediment and sedimentation was found to lower the annual benefits from reservoirs intended water uses in monetary terms. The Net Present Value (NPV) for removing and selling the accumulated sediment was found to be high and positive for all the dams while the NPVs for operating reservoirs with sediment in them were found to be low and sometimes negative values were recorded. It is concluded that the studied small dams in Lusaka and Southern Provinces were experiencing severe sedimentation which lowers the benefits from intended dam uses. Because of the high potential benefits that could be derived from sediment, local communities and dam owners should be encouraged to exploit this abundant natural resource in their areas.

The Net Present Value (NPV) for removing and selling the accumulated sediment was found to be high and positive for all the dams while the NPVs for operating reservoirs with sediment in them were found to be low and sometimes negative values were recorded. It is concluded that the studied small dams in Lusaka and Southern Provinces were experiencing severe sedimentation which lowers the benefits from intended dam uses. Because of the high potential benefits that could be derived from sediment, localcommunities and dam owners should be encouraged to exploit this abundant natural resource in their areas.

▼ Valdivia is a Chilean city located near an estuary system, 800 km south of Santiago. The navigation capacity of the Valdivia river mainly determines the present state and future possibilities for the welfare of the city. Since sedimentation problems arose in the river, the capacity for navigation became limited. The ministry of Valdivia therefore desires a solution for this problem in order to create possibilities for future growth. However, it is not known to what extent solutions for the sedimentation problem will actually contribute to an increase of welfare. By identifying the problem for the Ministry of Public Works of Chile, the boundaries and goal of the project could be set. In this research an attempt is made to answer the following research question: How can the surplus of sediment in the Valdivia river be remedied and to what extent will this contribute to the economic and social values of the city of Valdivia? In order to know how to remedy the surplus of sediment, a qualitative analysis of probable causes of the sedimentation was necessary. The main subjects which were researched by means of data and literature are tidal influence, river discharges, sediment composition and salt intrusion. With this knowledge it was concluded that the directions and magnitudes of flow lines in the river system can give good indications on what locations sedimentation can occur. The interaction between tidal currents and river discharges are the main drivers behind these flow characteristics. To verify the theoretical analysis, a basic Delft3D model was set up containing only tidal movement and river discharges. The pattern of the flow lines which was obtained from the Delft3D model supports the possibility that sedimentation occurs on the current identified sedimentation locations. Although other hydrological and morphological processes were found to possibly influence sedimentation rates in the river, qualitative data for studying these processes were missing. The current Delft3D model is therefore a good result regarding the available data and can be seen as a part of preliminary research in order to support further studies. Because the exact causes of the sedimentation were not identified in this research, it was not possible to come up with suitable solutions and to research how these solutions could affect the system. However, in order to gain insight in the effects of a river system without sedimentation problems, a fictitious scenario was studied by means of a social cost benefit analysis. The goal of the social costs and benefits analysis was to give insight in what factors should be taken into account when considering a project plan which solves the sedimentation problem. A dredging design was made in order to make the Valdivia river navigable for larger cargo vessels to increase the trading capacity of Valdivia. This dredging design comprises the deepening of the Valdivia river to a minimum water depth of 10 meters. Considering investment and maintenance costs of the dredging activities of this magnitude, it is… Advisors/Committee Members: Savenije, Huub (mentor), Labeur, Robert Jan (mentor), Pel, Adam (mentor), Delft University of Technology (degree granting institution).

▼

Embedding of subsea pipelines for protection purposes is usually done in a ‘Trench – Install – Backfill’ operation. The pipeline can also be embedded after it is installed on the seabed. This method is called post-trenching. When using a trailer suction hopper dredger for post-trenching, a large water jet erodes the soil underneath the pipe creating a temporarily trench in which the pipeline can sink. Large steel pipelines are inflexible and need a considerable free span to sink to the desired depth. The length of the trench is limited as the eroded sand that is brought in suspension starts to settle in the trench when the velocity of the suspension decreases. To be able to predict the length of the trench, the sedimentation velocity in jet induced flow is investigated in this research. The research describes the experiment series that is performed to investigate the behavior of a trench that is created by a vertical jet flow, trailing over a sand bed. The focus is on the sedimentation part of the trench. Concentrations and flow velocities are measured to determine the shape of the trench, the distribution profile and velocity profile. The experiments show a clear relation between the depth of the trench and the length that the trench is open. A deeper trench (due to a higher pressure or lower trail velocity) results in all experiments in a longer trench. The near bed concentration and the sedimentation velocity do not change a lot for different settings of the jet. To see if the theory on the sedimentation process can represent the post-trenching process, a calculation model is made that uses the theoretical concentration profile to calculate the sedimentation velocity. A good similarity was found between the model and the experiments. The experimental research on the sedimentation velocity in a trench that is created in a post-trenching process, indicates that sedimentation velocity is largely independent of the jet parameters. To make the trench longer, it has to be deeper to lengthen the path that the bed has to travel. A test with a second run over the bed proved highly effective due to the high porosity of the sand that settles in the first run, the maximum excavation depth is twice the depth of the first run. By implementing a pipeline in the experiment it is investigated if the pipeline has an influence on the flow conditions and sedimentation velocity.

▼ Student project report, in cooperation with Smith-Warner International Ltd. (SWIL), Kingston, Jamaica. At this moment the shipping channels in Kingston Harbour, Jamaica, slowly accrete. When the harbour is expanded, the local and global sediment transport is likely to change. During this project it is investigated whether these changes are significant and if they will have a negative influence on the Kingston Harbour area. Also the increase of flood risk for the area surrounding Hunts Bay is investigated. This investigation is done by modeling the hydrodynamics of the Kingston Harbour area with MIKE21 and Delft3D, where after both modeling programs are compared to each other. For the input data for the models, research has been done concerning the boundary conditions. This data is gathered from several projects done in the past about other areas in the harbour and fieldwork in Hunts Bay. During the year, most of the wind comes from the east and south-east direction. There are also two mayor streams which debouch into Hunts Bay, namely the Sandy Gully and the Rio Cobre. Since there is only discharge known about the Rio Cobre (daily values from 1985 to 2010), only the Rio Cobre is taken into account. The maximum measured value was 563 m3/s (during hurricane IVAN) and the average value is about 12 m3/s. For the sediment input data some fieldwork is done in Hunts Bay to gather information about the type of soil. From this it is concluded that it is silt, which is confirmed after a lab research of the sediment. However these accurate soil properties couldn’t be implemented into the models due to the lack of time. During the fieldwork also a bathymetric survey was done, which showed that Hunts Bay is sedimented compared to the previously used bathymetric data, gathered from admiralty charts in 2000. Calibration of both models is done by comparing it with the measured water level and flow velocities underneath the Causeway Bridge. Since this is the only point where data was available for, the calibration kept global, and should be improved in the future. The modeling showed that most of the sediment transport into the shipping channel is caused by the high discharge of the Rio Cobre. Ivan showed the most extreme sedimentation and the biggest change due to the expansion. In the present situation the shipping channel is gradually silting, with two areas where the siltation is concentrated. With the first phase expansion these ‘mountainous’ areas will be much more concentrated. However it can be concluded that the changes in the sediment transport due to the first phase expansion are not significant and will not lead to more problems than there are without this expansion. For this problem a sediment trap is proposed. At first it was placed just eastward of the Causeway Bridge, but this didn’t solve the problem and it would be in the way for the phase two expansion. Therefore a sand trap is designed in Hunts Bay, just westward of the Causeway Bridge. This location is really effective, since it stores the sediment from the…

▼ Cone penetration tests (CPTs) have been developed for engineering investigations of sands and finer sediments. CPTs produce high resolution, repeatable and continuous records to depths of several tens of metres, and resemble wireline logs used in the petroleum industry. It is the objective of this dissertation to demonstrate that they can be used for facies analysis in a similar manner, by using these data to develop a facies model for the modern Fraser River delta, British Columbia, Canada. CPT data provide reliable estimates of sediment type and gram size, so that bed thicknesses, sharp and gradational contacts, coarsening and fining upward sequences, bed continuity and dips can be readily identified. The facies model of the Fraser delta is based on a database of over 800 CPTs and 20 continuously cored boreholes. These data demonstrate that the topset is dominated by a nearly continuous sharp-based sand unit that is 8 to 30 m thick, fines upward and is interpreted to represent a complex of distributary channel deposits. The widespread distribution of this sand unit is the result of distributary channel migration in a tidal flat setting and avulsion or channel switching in the upper delta plain. The sand unit is gradationally overlain by a thinner sequence of interbedded sands and silts deposited in tidal flat, abandoned channel and floodplain environments. Deposits of the upper foreset (<60 m) dip up to 7° seaward and are dominated by silts, interbedded and interlaminated with sands. Several intergradational facies, ranging from dominantly silt to dominantly sand, occur and represent increasing proximity to active distributary mouths. These sediments are organized into metre-scale sandy and silty coarsening-upward sequences that are interpreted to represent annual deposits, and sharp-based sand units that represent sedimentary gravity flow deposits. Deeper foreset deposits are dominated by bioturbated silts. The distribution of facies on both the topset and the foreset has been controlled by the interaction of tidal and fluvial processes. CPT data played a key role in developing this facies model of the Fraser River delta. Most facies have distinct CPT signatures. For example, the topset sand unit and overlying deposits have a CPT signature comparable to the “bell-shaped” gamma ray log signature typical of channel deposits. In the foreset, the seaward dips, the coarsening upward sequences and the sharp-based sands are readily observable on CPT data. Although cores were essential to confirm the facies significance of these signatures, the large volume of CPT data permitted recognition of facies distributions and relationships “at a glance” throughout the delta, rather than at the relatively few site where continuous cores were available. Furthermore, CPTs can be acquired for a fraction of the cost of continuous cores, so that CPT data are potentially an invaluable tool for stratigraphic investigations of other modern sedimentary environments dominated by sands and finer sediments.

▼ Onshore-offshore and onshore wide-angle reflection and refraction seismic data are analysed in order to constrain the crustal P-wave velocity structure within Wanganui Basin and the southern Hikurangi margin, western North Island, New Zealand. Two, two-dimensional, P-wave velocity models are constructed using reflection and refraction phase travel-times based on forty-four onshore-offshore receiver gathers, twelve onshore shot gathers and two marine multi-channel-seismic reflection profiles collected along two transects within Wanganui Basin. The profiles are orientated both sub-parallel and perpendicular to the strike of the Hikurangi margin. Within Wanganui Basin, a north-south increase in Moho depth is resolved sub-parallel to the strike of the Hikurangi margin from 25 km depth north of Mt Ruapehu to 36.5 km within offshore Wanganui Basin at the latitude of Foxton. This increase is punctuated by an abrupt step in Moho depth of 7±3 km over a lateral distance of < 30 km from 25 km to 32 km depth slightly south of Mt Ruapehu. Perpendicular to the strike of the Hikurangi margin, the Moho is resolved at a depth of 35.5 km near the southern edge of the basin. A comparison between the Moho interpreted on multi-channel-seismic-reflection stacks and wide-angle reflection models suggests that the wider-angle Moho represents the highest amplitude reflector in a band of reflectivity that represents the Moho on the vertical incidence reflection stack. In this case, the Moho may be an extra ~ 5 km thicker than that determined in the wide-angle models. Nonetheless, these models confirm the crust in Wanganui Basin is anomalously thick, yet may be thinner than the previously thought maximum thickness of > 42 km by up to 5 km based on wide-angle data. The Australian/Pacific plate interface is imaged as a relatively smooth surface at depths of 28.15 - 35.6 km between the latitudes of Paekakariki and Foxton with apparent dip to the north-north-east increasing from 2.3 to 9.5°. Perpendicular to the strike of the Hikurangi margin, this interface increases in depth from 16 - 33 km with an increase in dip of 5.4° beneath Featherston to 19° beneath central Wanganui Basin. P-wave velocities range between 5.8 - 6.5 kms-¹ in the upper ~18 km of the crust within Wanganui Basin. These are interpreted to represent mid and lower-crustal rocks that have been emplaced in the upper crust by exhumation during the Miocene. In the lower crust P-wave velocities are inferred as 6.5 - 6.85 kms-1 sub-parallel and 6.5 - 6.65 kms-¹ perpendicular to Hikurangi margin, suggesting a lower crustal P-wave anisotropy of up to ~ 3% This may reflect the preferential alignment of mineral fabrics in the direction of relative transpressive plate motion during the Neogene and/or structural anisotropy parallel to the strike of the Taranaki Fault Zone and Kapiti-Manawatu Fault System. The structure of the Pacific plate crust is resolved as two layers. The top layer is inferred as a low-velocity sediment sheet with a P-wave velocity of 5.00 - 5.20 kms-¹ and thickness… Advisors/Committee Members: Stern, Tim, Lamb, Simon.

Due to the predicted impacts of climate change on the frequency of storm events, water managers are challenged to improve and adapt the current urban infrastructure. Cities need to be able to deal with the adverse effects due to more frequent and heavier rainfall. This implies the need for sustainable urban drainage systems (SUDS) that can deal with these challenges. SUDS can be seen as designs that can improve both, the quantitative as well as qualitative characteristics of stormwater. The study area in the south of Amsterdam will be equipped with a SUDS, namely a SediSubstrator L by Fränkische Rohrwerke. The objective is to remove particles from stormwater discharge to prevent clogging of the infiltration facility (AquaBASE) installed in sequence. Additionally, it can remove harmful pollutants which are adsorbed to the fine particles. This research aims to investigate the characteristics of the sediments in stormwater in theory and develop an appropriate sampling strategy to monitor the relevant parameters in the field. The long-term objective hereby is to determine the removal efficiency of the SediSubstrator L using a finite amount of parameters. To do so, a threefold approach composed by a detailed literature review, stormwater sediment sampling as well as a model simulation was used. Based on the identified parameters to be assessed, a specific monitoring and sampling setup is proposed to determine the removal efficiency of stormwater sediments in the study area. Along with the efficiency, the volume of sediments that are caught by the facility can be approximated. The latter needs to be removed once the entire storage volume of the sedimentation facility is filled. It is recommended that Waternet uses measured stormwater data to improve the model, while monitoring the efficiency under field conditions. Once the results of the model and the actual field measurements match, the model can be used to simulate the sediment removal for long time series. In this way the cleaning intervals can be predicted, while avoiding expensive long-term measurements to do so.

▼ Reservoir sedimentation is one of the temporally and spatially distributed challenges facing managers of small reservoirs today. Fluvial system formed the geomorphological plinth of the study. The study was motivated by the problem of sedimentation in the Makoye Reservoir (about 60500 m2 ), which had been affecting 474 pastoralist households rearing over 10,000 cattle. The objectives of the study were to: (i) determine the bathymetry of the Makoye Reservoir at different temporal scales; (ii) measure the long-term quantity of sediment deposited in Makoye Reservoir; (iii) determine the short-term real time sediment settling rate in the Makoye Reservoir; (iv) examine concentration levels of selected physical and chemical parameters of water for livestock in Makoye Reservoir; (v) evaluate the efficiency of Soil Water Assessment Tool in simulating sedimentation in the Makoye Reservoir; and (vi) to develop a conceptual model for understanding sedimentation process in small reservoirs in Zambia. The study used Critical Analytical Experimental Research Design implicitly inspired by Critical Empirical Analytic Paradigm. Five bathymetric surveys were conducted using a Remote Controlled Hydrographic Survey Boat with the aid of an inflatable boat. Sediment pits (195) were dug across the dry reservoir bed with aid of picks, ranging poles, measuring tape, Differential Global Position System and iron pegs. Real time sediment depth was measured using SediMeter SM3A, whose 36 Optical Backscatter Detectors captured sediment depth with resolution of 0.001 mm. The data inputs for Sediment simulation included the 90m Shuttle Radar Topography Mission Digital Elevation Model (SRTM DEM) , weather data, soils and landuse maps. Three soil samples (50cm) were collected using augers, and suspended and settled sediment samples were collected using grass carpets and coring. Bathymetric data was analysed using 3D Spatial Analysts Tools (3DSATs) in ArcGIS 10.3 and spreadsheet Microsoft Excel. This enabled determination of volumes, surfaces areas and development of hypsometric curves showing relationship among water depths, volume and surface areas. Real time sediment data was analysed using descriptive statistics and time series. Simulated sediment data was analysed using SUFI-2 in SWATCUP 2012. Soils, sediment and water physico-chemical analysis were done in the Soils Sciences and Environmental Engineering laboratories at the University of Zambia, respectively. Seasonal comparison of reservoir's bathymetries and water volumes showed drastic changes in average depths and volumes of water (24,830.93 m3 to 75,974.21 m3 ). This supply was below the water demand for cattle due to diverse physical processes (weather conditions, drainage hydro- geomorphology and mainly, sedimentation). On average, the real time daily sediment settling rate was 0.0003 m/day. Between 1988 and 2017, the average rate of long term sedimentation was 5,834.12 tonnes/year. SWAT efficiently simulated sediment with…

▼ Allochthonous litter inputs are a primary source of organic matter in low-order forested streams. A major component of this litter moves through small streams as fine particulate organic matter (FPOM). Litter decomposition has been well studied, but few studies have examined benthic FPOM (FBOM) dynamics. The purpose of this study was to investigate, (1) how FBOM is controlled by headwater vegetation, elevation and seasons, (2) the links between organic matter inputs and FBOM substrate quality and (3) the relationships between FBOM substrate quality and microdecomposer activity. In preparation for this study, the stability of various microbial and chemical characteristics of FBOM during storage and analysis was determined. Denitrification potential (DNJT), phosphatase activity (PHOS), and extractable ammonium (EA) remained stable over a minimum of 11 hours of storage at 5°C. Mineralizable N (NMIN), respiration (RESP) rates, and [beta]-glucosidase (BGLC) activity all decreased within 12 hours of collection. Results varied for nitrogen fixation (NFIX). In response to these results, our laboratory protocol was altered to accomodate analyses with varying levels of stability. Following this protocol, FBOM was sampled and analyzed over a 10 month period from 14 first-order streams in the Cascade Mountains of western Oregon. Streams ran through forests in three successional age classes: old-growth forest (OG) dominated by Douglas-fir (Pseudotsuga menziesii) and western hemlock (Tsuga heterophylla), and young regenerating stands (YS) either 10 years old, with a large riparian herbaceous component, or 30 years old, surrounded by deciduous trees such as red alder (Alnus rubra). Decreases in C:N, CTOT, NTOT and organic P (PORG) were mirrored by reciprocal increases in FBOM RESP, BGLC, PHOS and NFIX, all relative indicators of microbial activity. The lower C:N and higher DNIT, RESP, BGLC, PHOS, and NMJN observed in YS FBOM compared with OG suggests higher quality FBOM and faster decomposition rates in YS FBOM. Seasonal trends showed a major autumn deflection in FBOM C:N ratios and microbial activities, a likely result of increased leaf inputs following an early fall storm. Significantly lower C:N at high elevation (1220-1280 m) suggested the presence of more herbaceous vegetation and alder in high elevation riparian zones. Lower NTOT and CTOT and elevated DNIT, NFIX, RESP, PHOS at low elevation (580-800 m) suggested greater decomposition rates at low elevations. PORG was 2.2 and 3.6 mg P gOM1 at high and low elevations respectively, a difference (p<=O.O5) probably due to the young geologic age of parent material at high elevation. The data from this study suggest a potential link between headwater forest management and stream food web dynamics as mediated by shifts in FBOM.
