The study into sand wave dynamics in South Channel has commenced after large dune forms were observed in monitoring campaigns following the channel deepening project of the Port of Melbourne. The project involved deepening of the harbour berths and channels, but more importantly, it involved the deepening of South Channel in Port Phillip Bay. South Channel, the main shipping channel, crosses the bay over a distance of ≈20km. The growth of bedforms at various locations in South Channel now threatens to impede marine traffic. The dimensions and migration rate of the bedforms in the channel are remarkable, especially in the harsh flow conditions in the narrow channel. Therefore, the bedforms in South Channel cannot be given an obvious classification. The first part of this thesis studies the hypothesis that the bedforms in South Channel can be classified as tidal sand waves. Tidal sand waves are large-scale bedforms generated by recirculating flow cells that drive sediment to the top of a crest, and are commonly observed on shallow coastal seas such as the North Sea. The second part of the thesis explores different dredging strategies for tidal sand wave fields and these are assessed for the case of South Channel. The classification analysis follows two different directions. First, the dimensions of sand waves found globally are compared to the dimensions found in South Channel. Secondly, the flow conditions in the channel are compared to the tidal sand wave flow regime as defined in literature. This bedform issue in the channel properly illustrates the necessity of an evaluation of the current, and alternative, channel maintenance strategies. A numerical model in Delft3D software is used to assess the different strategies. Though the results of the model are promising, they cannot be applied straightforwardly to assess the navigability of South Channel for the various strategies. A probabilistic approach is applied to combine the insights from the numerical model and the survey data to produce the probability of breaching the maintained depth for the different strategies.

▼ The coastal protection system of the Dutch low-lying hinterland is under increasing pressure due to growing population and high economic value combined with climate change and a rising sea level. Supplying sand to dunes, beach and shoreface by means of nourishments is a widely applied technique to increase coastal safety. Climate change and a rising sea level lead to higher water levels and higher and longer waves at the North Sea. These increased loads cause a heavier impact on the Dutch coast and therefore, wave boundary conditions have been revised by the Dutch Government. After a reassessment of the coastal protection system in 2003, several parts of the Dutch coast did not comply with the safety standards and were appointed 'Weak Links'. The Hondsbossche and Pettemer sea defence was one of the weak links. The Hondsbossche Dunes nourishment provided the desired solution to improve coastal safety and at the same time maintain, and where possible, improve environmental quality. The design of the nourishment is of a magnitude that is unprecedented. It covers a stretch of approximately twelve kilometres of coast. In contrast to traditional nourishments that typically consist of about 1-2 million m3 of sand, the Hondsbossche Dunes nourishment contains a volume of 35.6 million m3 of sand. The implementation of nourishments modifies the topography of the bed and impacts the nearshore coastal regime. After the nourishment is constructed, the cross-shore profile evolves towards an equilibrium shape, and the shoreline planform adjusts via alongshore spreading. As a result, increased erosion rates are often observed in the first period after completion of nourishments. To improve the design of future nourishments, it is essential to understand and quantify the processes that govern the initial morphological evolution of recently completed nourishment projects. Twelve months after completion of the nourishment, sand losses at the Hondsbossche Dunes nourishment appeared to be large. This study focuses on understanding the processes that govern these large initial volume losses. Bathymetric data obtained from monthly monitoring surveys during and after construction, combined with wave forcing data are used to analyse morphological evolution and hydrodynamic forcing. Furthermore, a process-based cross-shore sediment transport model is applied to assess the relative contribution of several hydro- and morphodynamic factors on the initial morphological development of the nourishment in more detail. The results show that after twelve months 2.5% of the initially nourished sediment volume is lost from the project area. The high losses are mainly due to energetic wave forcing in the first twelve months after construction, with an average net northward transport potential that is 2.5 times higher compared to the long term yearly average. Morphological response is an event-driven process, such that large morphological changes coincide with months with energetic waves. About 60-80% of the volume changes occur over a period of only three… Advisors/Committee Members: G.J.%22%29&pagesize-30">Aarninkhof, S.G.J. (mentor).

▼ The Rhine ROFI ( region of freshwater influence) is a dynamic area where various processes and timescales come together. Research has shown that stratification caused by the freshwater outflow of the Rhine alters the tidal currents in front of the Dutch coast. In the case of the Netherlands the tide behaves like a kelvin wave, which causes rectilinear tidal flow. If the area is stratified this rectilinear flow becomes elliptic, the cross-shore component of the flow increases. As this happens the top and bottom layers of the flow become decoupled due to stratification. This results in two counter rotating ellipses. This behavior causes a cross-shore velocity shear in the water column. From high to low water the velocity shear in the bottom layer is offshore directed , from low to high water it is onshore directed. Research has shown that this cross-shore velocity shear causes extra sediment transport. This thesis describes the impact of the Rhine ROFI on the alongshore and cross-shore variability in annual cross-shore sediment transport in the depths from NAP-12 to NAP-20m between Hoek van Holland and Noordwijk. The stratification that drives the formation of tidal ellipses is dependent on the freshwater discharge from the Rhine, the spring neap cycle of the tide , the ebb-flood cycle and breakdown of stratification by wind and waves. To see the effect of stratification on the velocity field a D-Flow-FM model is used to simulate a two week period. This model includes the tide, wind and discharge. The necessary wave parameters to calculate the sediment transport are derived from a Delft3D-Wave model. This is an offline approach, so the impact of the waves on the stratification and flow is not taken into account. The flow field and waves are used to calculate the sediment transport with the total load Soulsby-Van Rijn formula. Five scenarios are run to assess the impact of different discharges. A reference scenario without the impact of stratification, three scenarios to simulate a year and an extreme scenario to see the impact of very high discharge. The effect of the wind is investigated by using a constant wind from the South-East and a no wind condition. From research it is clear that strong winds and high waves break down stratification. Due to the offline approach the effect of waves are not taken into account on the flow field. This has been taken into account in the sediment transport calculation by using flow results from the reference case that are without the effect of stratification for waves higher than 1.5m. The results show that there is an impact of the ROFI on the cross-shore sediment transport especially near the river mouth, this effect reduces in the direction of Noordwijk. The gradient in cross-shore sediment transport in the alongshore direction is negative, the transport reduces slowly in the direction of Noordwijk. The transport in cross-shore direction shows a high gradient near the river mouth at Hoek van Holland and a zero gradient further to the North. The results show that the effect of… Advisors/Committee Members: G.J.%22%29&pagesize-30">Aarninkhof, S.G.J. (mentor), Luijendijk, A.P. (mentor), Meirelles, S. (mentor), Rijnsburger, S. (mentor).

This document describes a study into the influence of alongshore bathymetric variability on currents which form a risk to bathers. Changes to coastal zone management along the Delfland Coast have given rise to questions on the influence of alongshore bathymetric variability on bather risk. Extensive measurement data is available from two measurement projects, mapping the entire Delfland Coast. This data has been used to study the presence and development of alongshore bathymetric variability along the Delfland Coast. Subtidal variability was found to generally increase during the winter months, in accordance with literature. In the intertidal area variability was found to decrease in the winter months. Both intertidal and subtidal variability were found to be relatively low near the breakwater at Hoek van Holland. The range in measured variability along the Sand Motor was found to be very wide. Using a parameterization of the alongshore variability, subsections of the Delfland Coast have been selected for a modelling study. Artificial bathymetries have been created, using the selected measurement data. These artificial bathymetries have been used as the basis of numerical models. These have been forced with linearized wave conditions, in order to investigate the relation between different levels of alongshore bathymetric variability and wave induced currents which might form a risk to bathers. Good correlations were found between the alongshore variability and the wave induced currents, especially for the intertidal area. Alongshore bathymetric variability seems to be an important factor in generating wave induced currents which might form a risk to bathers. In order to be able to fully assess the influence of the bathymetry on such nearshore currents, the influence of the depth of the variable bar patterns, the distance between the subtidal bar and the intertidal bar and the phase differences between the subtidal and the intertidal bar need to be investigated further.

The applicability of the open source model XBeach was tested for pocket beaches in this paper. First, schematized model setups have been used to assess the performance of XBeach qualitatively. It was found that adjustments of the initial bed were required to obtain the expected hydrodynamic conditions. The default sediment advection calibration factors had to be increased to obtain the expected morphological response of the pockets (stationair: 0.15, surfbeat: 0.30). The results have shown that the surfbeat mode outperforms the stationary mode based on a qualitative assessment. It was furthermore found that wave-current interaction produced unreliable results and should be avoided when modelling pocket beaches using XBeach. Non-hydrostatic simulations produced significantly more sedimentation behind the headlands due to the inclusion of diffraction. This mode was found to produce unexpected erosion at the upper shoreface however, indicating the inapplicability of the sediment transport formulas in non-hydrostatic simulations. Expansion of the classic pocket beach into two adjacent pocket beaches showed that these systems have to be treated as a complete system if interactions between these pockets are expected (separated by a salient). It was found that an individual assessment is adequate if a tombolo separates the pockets. Second, the morphological developments between the year 2000 and 2015 at Tanjong Beach (Singapore) were modelled using XBeach. For the modelled bed level changes, which were compared to bathymetric measurements, a ‘Good’ Mean-Squared Error Skill Score of 0.31 was found. In the prepared model, the obtained sediment advection calibration factors from the first part were used and model calibration was not performed. Based on the schematizations and the case study performed in this study, XBeach was found to be applicable for long term process-based modelling of pocket beaches.

XBeach is a process-based morphological model that has been used for modelling short term behaviour of beaches and dunes. In the past years interest has been shown by researchers and engineers to use XBeach for longer simulation periods (multiple years). XBeach has multiple modules: stationary mode is often used during calm conditions and surfbeat mode is often used during storm conditions. In this study was investigated whether the coupling of the two modes can increase the performance of long-term models compared to the separate models, while focusing on the cross-shore processes. Also the added value of (quasi-)2D models was studied. The high frequency bathymetryic data of Vlugtenburg, an alongshore uniform beach in The Netherlands, was used for creating 1D models for a period of 1 year. To compare the difference between singular and coupled models, first the potential performance of the stationary and surfbeat modules was investigated separately by optimising the settings for asymmetry, skewness and groundwater flow. It was found that the skill of the stationary and surfbeat models with default settings was negative. Erosion was overestimated (especially in surfbeat mode) and the models showed no seasonal effects. Settings for asymmetry and skewness proved to be effective measures to improve the model performance and were able to introduce seasonal effects. The optimised stationary model was able to predict the profile development reasonably well. The groundwater flow module did not affect the model stability as much as was found in the studies of Zimmermann et al. (2015) and Pender (2013). In order to validate whether a coupling between stationary and surfbeat mode would benefit the model performance, it was investigated whether stationary mode was able to restore the dune and beach erosion of the surfbeat model. Therefore surfbeat was run during the first 100 days of the year (during more extreme conditions) and stationary mode during the remainder of the year (more mild conditions). Stationary mode appeared not to be able to restore the eroded surfbeat profile. The performance of the coupled model was better than the surfbeat model, but the stationary mode was found to perform better than the coupled model for long-term modelling on the most criteria. It was found that a deficiency in XBeach is the ability to transport sediment from the intertidal zone (and just above) further up the beach and dunes. The erosion volumes in the dunes in stationary mode were in the same order of magnitude as the onshore directed aeolian transport. Therefore is expected that the results of long-term models can be improved by coupling XBeach with a wind model. The quasi-2D model was found to have a better performance than 1D models due to the spreading of infra-gravity waves in 2D; in both the separate and coupled models the erosion volumes were not overestimated as much as in the 1D models.

Coastline regression is a significant threat to many coastal zones. Being able to mitigate the erosion while simultaneously improving nature development is something that is increasingly strived for in coastal projects. This report utilizes the building with nature philosophy to explore integrated solutions for a coastal erosion problem in Negril, Jamaica. Erosion of the coast is threatening the many hotels and resorts along the beach near Negril. The hotel owners and the local community are looking for a sustainable solution to the erosion problem. The building with nature approach starts with the system in mind, not the intervention. First the cause of coastal erosion is better understood. A combination of factors is responsible of which the intensification of storm events and degradation of the environment are two of the main causes. A reduction of the sediment production rates could also have led to increased coastal erosion. Due to the lack of data in this phase of the project, the exact reason cannot be identified. Therefore, both scenarios are considered. From there, different solution strategies are explored and alternatives are identified. The strategies range from environmental solutions to soft, hard and hybrid solutions. These designs are simulated to understand their effectiveness by relative comparison. Alternatives that do not work as intended are excluded. The evaluation of the remaining alternatives shows what the strengths and weaknesses are of the different solution strategies. A social evaluation method is also applied to assess the applicability of this type of evaluation method and gain a broader perspective on the alternatives. If restoration of the natural sediment production leads to large production rates and a large improvement in overall environmental quality, then this solution strategy could be very positive. Nourishment strategies work well from a social and technical point of view but less ecologically. The nourishment strategies can be improved by adding environmental improvements to the alternatives. A hybrid solution has the potential to provide a positive effect on the technical, ecological as well as social aspects of Long Bay. However, this depends on the applicability of Reef Balls in breakwater designs and the effectiveness of coral transplantation. The BwN approach ensures that a wide range of solutions is considered. The results give more insight in the cause of the coastal erosion and possible solution strategies for Negril. Using the knowledge gained in this thesis, more detailed alternatives can be obtained in the future.

Knowledge of seafloor topography (bathymetry) is increasingly important as coastal environments are unprecedentedly stressed by climate change and anthropogenic pressure. The bathymetry of shallow nearshore waters is yet marginally monitored due to costly and time-intensive survey techniques. Methods to obtain satellite derived bathymetry (SDB) have become increasingly valuable. Mapping temporal change is however challenging, because the majority of these methods remain heavily dependent on situ observations. This thesis introduces an SDB approach to estimate temporal bathymetric changes, which omits the need for synchronous in situ data. The approach is based on a reference image correction method that enables direct comparison of multitemporal imagery and temporal extrapolation of a conventionally-trained bathymetry estimation model (BEM). Research focused on pre-processing multispectral imagery, developing a bathymetry estimation model and estimating bathymetry for times of absent in situ data. The proposed method is demonstrated with a case study in the Dutch Wadden Sea; a site characterised by dynamic morphology, high turbidity and homogeneous bottom type. A log-linear estimation model is obtained by linear regression on in situ observations and the three visible bands of Sentinel-2 imagery. Scarcity of high-quality Sentinel-2 imagery is managed by combing multiple images into a six-month composite. The availability of two sets of vaklodingen in situ observations allowed for training and testing two bathymetry estimation models (BEM 2016 and BEM 2019) and for cross-validating the depth estimates after a three-year extrapolation of these models. Bathymetry is estimated for times of absent in situ data by temporal extrapolation of the two estimation models. The extrapolation showed estimation of shallow bathymetric structures in up to four metre water depth with an RMSE of approximately one metre. Additionally, the migration direction of these bathymetric structures is successfully estimated. Within the tested three-year time frame, predictive power did not decrease. These results imply that estimation performance is governed by composite quality and predictive power of the bathymetry estimation model. The limited influence of temporal extrapolation on estimation performance suggests that the availability of high-quality satellite imagery and one set of non-synchronous in situ observations is sufficient to estimate bathymetry for times of absent in situ data. The proposed method potentially provides a tool for mapping temporal bathymetric changes of nearshore zones across the globe.

▼ To help to provide a desperately needed coastal protection strategy for the Mekong Delta in Vietnam this research looks into the possibilities for natural and sustainable coastal defence systems, including mangroves and active sediment management, such as a nourishment. The coastline of the Mekong Delta suffers from severe erosion and mangrove degradation. Due to relative sea level rise and climate change it is crucial to design adaptable and proactive coastal protection measures. From a literature study into ongoing erosion processes, local coastal protection problems, and mangrove habitat requirements, boundary conditions were determined. As a basic concept of a Building with Nature alternative for the Decision Support Tool, a combination of a mangrove fringe with its accompanying wave attenuating foreshore and an earth dyke were considered. Two requirements with respect to a maximum wave height in front of the mangrove fringe and earth dyke, were translated into a conceptual profile of the foreshore: a convex-up bathymetric profile. This schematised profile was adjusted for two case study areas. The numerical model SWASH was used to translate the offshore boundary conditions into near shore conditions. Annual and heavy storm conditions were modelled for both case study areas, in order to test the performance of the convex-up profile. The model results led to designs of the foreshores of the case study areas. Possible dredging locations, equipment, transport of the dredged material, and different nourishment techniques were considered. The proposed Building with Nature designs and design alternatives were compared with current coastal protection measures by a cost-effectiveness and cost-benefit analysis. It was found that a convex-up profile improves the conditions for mangroves to develop, as this significantly decreases the hydrodynamic forces in front of the mangrove fringe and creates an additional zone above Mean Sea Level suitable for mangrove colonisation. The minimal required width for mangroves to serve as a self-sustaining coastal protection measurement is dependent on multiple factors including fringe density and local hydrology. The minimal required mangrove width was established to be 700 m for the case study site of Tam Giang Dong at the east coast and 350 m for An Minh at the west coast, where the hydraulic conditions are milder. The point at which full restoration of the convex-up profile can compete economically with a breakwater is dependent on the foreshore profile and erosion rate. For the east coast, in order to maintain the present situation, an erosion rate of 24 m/year or less was determined as the tipping point. For full restoration of the convex-up profile to be economically favourable the upper limit of the erosion rate is 20 m/year. For the west coast these points are 17 m/year and 10 m/year respectively. For the case study site of Tam Giang Dong, as well as for the case study site at the east coast, due to high erosion rates and high cliffs in front of the mangrove fringe, the proposed… Advisors/Committee Members: G.J.%22%29&pagesize-30">Aarninkhof, S.G.J.

The Houtribdijk is a dike intersecting the IJsselmeer and Markermeer, and is partly reinforced by the construction of sandy shores. The sand eliminates the wave loads before they can reach the levee. Making use of sandy shores as flood protection in a freshwater lake environment is unique. The main goal of this thesis was to find the causes of the formation of beach cusps and their morphodynamic behavior at the Houtribdijk. From a literature study, we had found that high-angle wave instabilities are the likely cause of beach cusp formation. This mechanism causes longshore transport of sediment due to differences between wave run-up when waves arrive at the beach under an acute angle. Low-energy environments like these are influenced by higher-energy (stormy) events, caused by wind forcing that produces short, steep, and erosive waves. Topography and bathymetry measurement data along two kilometer-long transects was available, as well as constant hydrodynamic measurements at two locations. Using this data, we quantified the number of cusps, their alongshore position, wavelength, amplitude, and the asymmetry of their top-view shape. By extrapolating the prevailing theory on high-angle wave instabilities, we arrived at a conceptual model for the large scale (kilometer-long) morphological changes of the beach. This conceptual model then related these changes to the hydrodynamics we thought were responsible. The results of this analysis indicate that the number of cusps increases under the influence of high-angle waves. Also, their peaks will start moving in the same direction as the waves, causing them to ‘lean’. Most of these changes are on a time-scale in the order of days, while some larger features migrate in the order of months. We have found that environments like these are very likely to develop beach cusps.

The Engineering Office of the municipality of Amsterdam is developing six man-made islands in the IJmeer. One of the last islands will be Buiteneiland. The location and orientation of Buiteneiland is been agreed when IJburg was designed. The area of interest of this study is the land-water transition at the east side of the island. The IJmeer's morphology is storm driven and the prevailing waves in this low energy environment, have limited reshaping capacity. Therefore, the land-water transition needs to consist of erosion protection. At the same time, the east side of the island will contribute to the 'Boog om de Oost', a provincial arch that connects the province of Utrecht with North-Holland via outer dike reed fields. For the Engineering Office, this was the reason to ask for an approach to deal with a hybrid solution, that combines a nature-based foreshore with an erosion protection for the east side of Buiteneiland. Figure 2.a and Figure 2.b shows two possible land-water transitions, a traditional dike and a nature-based hybrid solution. This composed the research question for this study: What is a safe and nature-based hybrid solution for the case study: east side of Buiteneiland, IJburg?. Design of alternatives for the nature-based hybrid solutions is done according to the method of de Vries et al. [2016]. This Building with Nature method is developed for nature-based type of projects. The Building with Nature method contains the five clear steps that have been worked through iteratively. The most suited nature-based hybrid solution for the east side of Buiteneiland seemed the Hard Arch variant (see: Figure 3) When implementing a nature-based hybrid solution, components and concepts of this solution can be extracted and implemented individually. New build or restored land-water transitions at least consists of a vegetated foreshore. The dike of the Basic Concept (is a dike without a foreshore or vegetation), covered by grass requires a crest height of 2.27 m. The hybrid solution as the Hard Arch variant, the grass covered dike only requires a crest height of 1.61 m, while offering the same protection level. The costs estimate for the found hybrid solution is a factor 5.5 higher than for the Basic Concept. However, the hybrid solution does have a lot of extra benefits next to safety. A lot of natural capital is added to the IJmeer and for the citizens of Amsterdam, in terms of vegetation above and below the water surface. Furthermore, social value and inspirational values are added to the Markermeer, where other new islands or shore restorations can be inspired by this nature-based hybrid solution. Thus, this nature-based hybrid solution is more expansive, but a solution like this maximizes the benefits for local communities, nature and economy. Overall, the use of a nature-based hybrid solution is a way of combining the development of new nature and ecosystems with coastal protection providing safety and prosperity for local community.

<p class="MsoNormal">As Chinese economy booms during recent decades, river management attains more investment, and is required to develop more rapidly for flood defense as well as facilitating navigation, which brings a lot of changes and threat to most of aquatics, especially those endangered species. Yangtze finless porpoise is one of those endangered species, of which the habitat is faced up with severe threats from hydraulic engineering. Hechangzhou reach, situating in the lower Yangtze river and 250kmupstream from the Yangtze river estuary(Shanghai), is one of the important navigation channels in Yangtze river and is also one of the main nature re serves for Yangtze finless porpoise. In order to adjust the discharge distribution of the two branches in Hechangzhou reach, Chinese Department of Water Resources conducted a project to construct 2 submerged sills in the north branch of Hechangzhou reach.Acknowledging the importance of both navigation development and protection of endangered Yangtze finless porpoise, investigating the impact of two sub merged sills on the physical habitat of Yangtze finless porpoise is necessary. This requires a good understanding of the hydrodynamics changes caused by two submerged sills as well as the requirements from Yangtze finless porpoise on its physical habitat. In this thesis, a study is performed to find a reliable evaluating system of Yangtze finless porpoise's physical habitat quality under the impact of hydraulic engineering. Habitat suitability index model, developed by the United States Fish and Wildlife Service (USFWS or FWS),is applied to the physical habitat of Yangtze finless porpoise. By literature reviewing and inquiring biologists, the vital ecological behaviors of Yangtze finless porpoise are identified as movement and feeding, and vital habitat variables are identified as water depth, flow velocity and substrate type. A previous developed hydro-morphodynamic numerical model was made available and is further developed to gain a better understanding of the changes to local hydrodynamic variables such as water depth, flow velocity. Substrate type, as one of the identified habitat variable from the results of habitat suitability index model, is determined by taking as implified method of comparison between soil critical shear stress and local bed shear stress. Three scenarios are designed to simulate the situation in the dry, normal-water and monsoon season. This thesis forecasts the changes to the physical habitat quality of Yangtze fineless porpoise through understanding the changes to local hydrodynamic condition and combining the results from habitat suitability index model. Overall,the submerged sills offer limited potential habitat area, slightly extend the high-quality habitat area and improve the existing habitat.

▼ About 80-90% of U.S. East Coast barrier beaches have experienced erosion in the last 100 years. South Carolina’s coastline forms no exception, a third of its developed shoreline experiences erosion. Among these eroding shorelines is Hilton Head Island, the second largest barrier island on the U.S. East Coast. Until now, erosion here has been addressed through traditional local beach nourishments. An alternative approach to the traditional nourishment method, are so-called feeder nourishments or feeder beaches. The potential advantages of the feeder nourishment concept over the traditional method are reduction of the nourishment frequency, containment of the ecological stress in a relatively small area, and a short to medium term increase of local available space for recreation and the environment. Given the potential advantages above, the residents of Hilton Head Island asked TU Delft to investigate the possibility of applying a feeder nourishment at their shoreline. Currently, a pilot project known as “The Sand Engine” is examined along the Dutch coast. Several studies into its morphological behaviour show that this feeder nourishment can be beneficial to the sediment budget of a larger coastal cell. Because of the promising results at the Sand Engine pilot project, it is tempting to state that a feeder-nourishment could also be applied at Hilton Head Island. The problem, however, is that the conditions at Hilton Head Island and the Sand Engine are different. There are two main differences between Hilton Head Island and the Sand Engine. First, Hilton Head is subjected to a relative calm wave climate in comparison to the Sand Engine. Second, the presence of two tidal inlets at Hilton Head, compared to a relative straight and uninterrupted coastline at the Sand Engine. As a result, the conclusions drawn from the Sand Engine pilot project do not necessarily hold for Hilton Head Island as well. The main objective of this thesis is to analyse the morphological behaviour of a feeder nourishment located at Hilton Head Island. First, to study its potential as a measure against erosion at Hilton Head. Second, to compare its morphological behaviour to that of the Sand Engine. And third, to be able to examine the potential of the concept for the Atlantic southeast coast of the U.S. in general. The morphological development of a feeder nourishment at Hilton Head Island was simulated with Delft3D over the course of 1 year for different model scenarios, with varying forcing conditions and varying bathymetric features. The effect of the relative calm wave climate at Hilton Head Island in comparison to the Sand Engine is twofold. First, the contribution of wave forcing to the total erosional volume of the feeder nourishment after 1 year is smaller as compared to the Sand Engine. Eliminating all driving forces besides wave forcing reduces the total erosional volume to 58% at Hilton Head, in comparison to 75% at the Sand Engine. Second, the contribution of storm events to the total erosional volume after 1 year from the feeder… Advisors/Committee Members: Hopkins, J.A.

▼ Degrading mangrove forests and coinciding erosive coastlines is an urgent global concern. Mangroves are essential for their interaction with hydrodynamic and sediment processes at mangrove-mud coasts. Earlier on, solutions were sought in building ’hard’ structures, such as concrete sea walls, to lower incoming wave energy and enhance sedimentation to restabilize erosive coastlines and bring back mangroves. As these approaches proved to be counterproductive and even accelerate destabilization of the coastline, nature-based solutions might provide a new path to a durable solution. A pilot project was initiated in Demak, Indonesia, where several permeable brushwood and bamboo dams were constructed near the receding coastline. The open structure of the dams allows sediment to ﬂow through, while they decrease wave heights by dissipation. This creates calmer conditions behind the dams and allows mud to settle. The deposition of ﬁne sediments enhances a rise in nearshore bedlevel and provides nursery ground for mangroves to reestablish, realizing a ﬁrst step towards rehabilitation of the mangrove ecosystem and restabilizing the coastline. A conceptual 2DH process-based model, using Delft3D FM, was created to analyse the effect of permeable structures under changing boundary conditions at various shorelines. Three boundary conditions were varied to see the influence on dam performance: wave height, wave direction and suspended sediment concentration. A decrease or increase in wave height resulted in similar rise in bedlevel elevation behind the dams. Without the dams, an increase in wave height increased the tidal ﬂat elevation and steepened the foreshore, inducing a concave proﬁle shape. Placing the dams on the tidal ﬂat induces extra rise in elevation, but won’t mitigate the erosion of the foreshore. Smaller wave heights tend to reshape the proﬁle towards a more convex proﬁle. When dams are implemented on, an increase in bedlevel behind the dams occurs. The waves stir up sediment at the tidal ﬂat boundary which are redistributed by the tidal currents forming a more convex proﬁle. The dams could be placed best close to the shoreline to allow for the natural redistribution of the sediment when at the same time induce a rise in bedlevel for mangroves to reestablish. Altering the nearshore sediment supply affects the dam performance signiﬁcantly. The dam performance increases for lower sediment supplies. Dams reduce erosion due to decreased sediment input, but it is likely a short-term solution. For higher sediment supplies, the coastline can more effectively restore by itself and the dams reduce in efﬁcacy. The model results show an increase in dam performance for increasing wave angles (shore-normal to shore-parallel). The bed shear stress is decreased more effectively for smaller wave angles, but also reduce the sediment concentration behind the dams. With the many distinctive boundary conditions at mangrove-mud coasts in mind, the simpliﬁed model setup is made easily adaptable to enable future use of the model.

=Introduction= Worldwide there is an increasing amount of dredging activities, due to increasing demand for transport of goods over the world. These project are more and more near sensitive nature reserves and thereby a potential threat of biodiversity; which is a major concern for port developers, authorities, environmental organizations and dredging companies. This research has emerged from the execution of Khalifa Port in Abu Dhabi; a project which lasted from February 2008 to July 2010. Turbidity in the water column (near coral reefs) was one of the main problems affecting Boskalis’ workability. Predefined, tight and fixed turbidity levels, valid for the whole site and execution period, were not allowed to be exceeded without adverse measures for the dredging company. The client had stated that the dredging company would always be responsible for the measured turbidity values; no matter what cause. An extensive data set resulted from this project. === Objectives === The aim of this research is twofold and can be related to the following research key objectives: The goal of this study is to gain insight in the relevant processes that result in the behavior of fines. Set up a simplified conceptual model be used as guidelines for future projects. === Approach === Research was done, following two approaches. First, the turbidity data set was analysed, where the relation was made with occurred hydrodynamics. The pre-dredging period was considered to capture the natural conditions leading a conceptual understanding. Understanding of Khalifa data can be used for in general guidelines for projects with similar environmental issues. Second, the behavior of suspended fines with a resuspension origin was simulated in an idealized model set up, this to improve understanding and secondly to create the ability to anticipate on turbidity events with regard to planning workability.

▼ In 2003, a first proposal for identification of seaward development, preliminary in combination with residential building, was presented in the Chamber of Deputies and within the States-Provincial (South-Holland), by respectively Geluk and Waterman. In response to this proposition, the ministry started an investigation, but concluded there was no support for seaward development financed through residential housing. Consequently, the initial proposal was adjusted. A feasibility analysis was made for seaward extension together with extensive possibilities for nature and recreation. A follow-up investigation (2005) indicated a large need for nature and recreation in the conurbation of Western Holland. In 2006, commission Tielrooij urged the necessity of a combined approach of the Delfland coast for sustainable long-term flood protection with expanding spatial qualities. The commission recommended a research into innovative civil methods for sustainable flood protection and expanding spatial qualities, among which mega-nourishment is recommended. In April 2008, an agreement is signed, by all concerning governmental stakeholders, for coastal expansion according to the principle “Building with Nature”. This agreement enables the start of a process to examine and investigate the execution of a so-called “Zandmotor” (hereafter sand-engine) at the Delfland coast. Begin 2009, the Environmental Impact Assessment “pilot project sand-engine” was published, in autumn 2009 the decision was finished regarding the financial costs for the Province and the Department of Waterways and Public Works. In March 2011, the execution of the sand-engine started near the Delfland coast. EIA, based on long-term morphodynamic prediction The Environmental Impact Assessment for the pilot project the sand-engine is based on long-term morphodynamic predictions, made with a single numerical software model called Delft3D. This model calculated the morphological development of the sand-engine for 20 years in advance, using average hydrodynamic conditions. After the EIA and during the construction of the sand-engine new problems and questions arose among stakeholders concerning e.g. groundwater flow, swimming safety, impact storm events, aeolian transports, etc. These uncertainties were not modeled and simulated, and are not included in the EIA. Idealized model approach Because there was a lack of an integrated design approach during the EIA phase of the sand-engine, this thesis includes an idealized design approach for mega-nourishments. Due to this idealized design approach multiple physical processes can be integrated using several numerical models for accurate long-term modeling of mega-nourishments. One integration, in this idealized design approach, concerns the impact of storm events within long-term morphological predictions. The integration of storm events within long-term morphodynamic predictions, is made possible within this thesis, by coupling two numerical software models, Delft3D and XBeach.

▼ The flow and sediment transport in the Yangtze Estuary are intrinsically complex because various processes and mechanisms are involved on a large range of temporal and spatial scales. In this thesis the interaction of river discharge and tidal wave with the corresponding sediment transport in the Yangtze Estuary is investigated. The objective is to gain further understanding of the processes and mechanisms dominating the sediment transport in the estuary. Based on the understanding of flow and sediment transport, a morphodynamic model is established and tested to simulate the morphological change of the Yangtze Estuary. Supported by a literature survey reviewing previous studies, the observed data (including water levels, currents, salinity, sediment concentration, sediment samples, etc.) at various stations under different conditions (spring/neap tide, dry/wet season, etc.) are first analyzed to investigate the characteristics of flow and sediment transport in the Yangtze Estuary. Subsequently, a process-based model based on Delft3D is set up for the estuary. After being calibrated and validated against measurements under various conditions, the model is used to simulate the sediment transport at the mouth bar of the Yangtze Estuary. Scenarios of model simulations are designed to account for different combinations of processes and mechanisms contributing to sediment transport. The results demonstrate that taking salinity processes into consideration is a prerequisite to understand how fine sediment has been trapped in the mouth bar area of the Yangtze Estuary in the last half century. It is also concluded that flocculation of fine-grained sediment in suspension enhances the sediment deposition in the mouth bar area. The net effect of all sediment transport processes is typical sedimentation in the wet season and erosion in the dry season, with net deposition annually. A decreasing trend in the annual net deposition has recently become visible. The deposition rate at present is down to 1/3 of the magnitude in the past.

The coastal area is a busy area, many people live in these areas or use the coastal area for recreational purposes. The beach profile in the coastal area is continuously changing under the changing field conditions. These changes are induced by the changing sediment transports in the sea under changing field conditions. Several models have been developed to simulate and predict these changes in sediment transport and their related profile changes. However, these models fail in a region close to the shoreline, since the parameterized wave models (like Battjes Janssen, 1978) fail in this region. In this thesis a model has been developed to compute the sediment transport rates up to zero meter water depth. This Inner Surf Zone (ISZ) sediment transport model is based on the ISZ model of Aarninkhof, 2000, which models the wave height decay and the associated flow field up to zero meter water depth. The ISZ sediment transport model uses the energy approach of Bailard (1963;1966) for the sediment transport computations. According to Bailard the sediment transport is related to the work done by the fluid, the dissipated energy. The sediment transport is divided in two layers in the ISZ sediment transport model, an upper and a lower layer. In the lower layer suspended and bed load sediment transport is taken into account. In the upper layer only suspended sediment transport is computed, based on the shear stresses near the bottom. The sediment concentrations in the upper layer are assumed to decrease, when the water depth increases, resulting in a decreasing sediment transport in the upper layer. Implementation of this assumption by an empirical formula into the model works encouraging well. The model is calibrated against the tests of Koomans in the Scheldt flume (2000). The model is valid for spilling breaking and the computation area is determined by the non-linearity parameter of the waves. The non-linearity parameter depends on the wave period and so does the range of the model. Different field conditions have been investigated in this thesis. Changing transport rates for varying beach slope and sediment composition can be modelled encouragingly well by the developed ISZ sediment transport model. The ISZ sediment transport model requires adjustment when field conditions like wave height and wave period change, since the friction factor and the sediment concentrations change under changing field conditions. Based on the described changes in sediment transport in literature, under these changing field conditions, a recommendation is made how to adjust the model parameters. The friction and the bed/suspended load efficiency factors are used to represent the described changes in sediment transport under these changing field conditions.

▼ The Markermeer is an important fresh water lake in the centre of the Netherlands. Because of its variety of functions and total scale of the lake, it is a unique area in Europe Over the years several problems have arrived in the Markermeer, which affect appropriate functioning of the lake. One of these problems is the decreasing ecological value (water quality) of the lake. This decrease in water quality is caused by a high turbidity of the water in the lake. Large amounts of mud sediment are suspended in the water column, even during normal conditions. This high turbidity has a large impact on the ecosystem. Rijkswaterstaat set up a study about several measures to decrease the high turbidity and improve the water quality of the lake. One of those measures is a deep silt trap, to catch the suspended sediment. Although some previous studies are carried out on the sediment behaviour in the Markermeer, the functioning of a silt trap is unknown. This MSc study focused on the mud dynamics in the Markermeer and the effects of a silt trap as a solution for the turbidity problem. Main question in this study is: Is a silt trap an effective measure to improve the water quality in the Markermeer? During construction of deep sand mining pits in the Markermeer, sedimentation rates in those pits were observed very high. Higher than expected from only settling of sediment from the water column. It is hypothesized that two mechanisms are responsible for the infill of the silt trap: settling of sediment from the water column and density currents. Density currents can be generated if a high sediment concentration layer exists near the lake bed and a density difference is present between two locations in the lake (for example near a silt trap). Field measurements showed that a high concentration layer (up to 800 mg/l) can exist near the bed of the Markermeer, under certain circumstances. To study the effects of a silt trap, a Delft3D model of the Markermeer is developed, which include the effect of density currents. This model showed that density currents can exists near a silt trap if the sediment concentration increases to 1 g/l near the bed. This occurs one day after a storm period. The dominant mechanism that fills the silt trap, differs for the two sediment fractions used in the model. For the fine fraction advection and settling of sediment is dominant. For the coarse fraction both mechanisms occur, although the settling process is of major importance. Also the effects of some design parameters of the trap are investigated, for example the orientation of the trap to the main flow direction (parallel and perpendicular). In both orientations a silt traps causes a reduction in concentration and an accumulation of sediment. However, a silt trap orientated perpendicular to the main flow direction has a higher efficiency. In the parallel case the trap attracts flow and causes an increase in flow velocity and turbulence intensity. This yields an increase of sediment in suspension which decreases the generation of density currents.… Advisors/Committee Members: J.F.%22%29&pagesize-30">Stive, M.J.F. (mentor), Winterwerp, J.C.
