Gundlach, Jannek (author)This graduation project investigates the main processes that are influencing the morphological development of the Outer Weser estuary by setting up a process-based model (Delft 3D) and applying it by means of simulating multiple scenarios, each driven by a different forcing. The aim of this project is to gain insight into the causes for the...master thesis 2018

Ahmad Azimi bin Kamaluddin, Azimi (author)Mangroves are tidal trees commonly observed along the sheltered shorelines of most tropical (from equator to 23.5° North and South latitude) and few subtropical (23.5° to 40° North and South latitude) countries. These plants are adapted to loose wet soils, saline habitats and periodic tidal submergence. With more attention paid into the approach...master thesis 2017

Hoek, Jordi (author)The St Lucia Estuary is Africa’s largest estuarine system and part of the iSimangaliso Wetland Park, which was listed as South Africa’s first World Heritage Site in December 1999. The St Lucia Estuary is connected upstream to Lake St Lucia and downstream it flows into the Indian Ocean. The St Lucia Estuary is located at a wave dominated coast...master thesis 2017

Ostanek Jurina, Tadej (author)In large braided rivers, river training is often required to protect the banks against erosion, to improve navigability and for land reclamation. Closing one of the channels is a promising option to achieve these goals. However, there is a lack of systematic research on channel closures and no guidelines for their use exist. In the few...master thesis 2017

Athanasiou, Panos (author)Crescentic sandbars are a commonly observed nearshore feature in coastal zones that strongly influence the surfzone circulations and are connected with the occurrence of rip currents. Furthermore, their spatial characteristics have been associated with the shoreline position in the form of shoreline perturbations, indicating morphological...master thesis 2017

Leal Campos Fonseca da Silva, Renan (author)Spurs-and-grooves (SAG) are a common and impressive characteristic of shallow fore reef areas worldwide. Although the existence and geometrical properties of SAG are well-documented ever since the 50’s, the literature concerning specifically the hydrodynamics around them is sparse. This study provides a characterization of the 3D flow patterns...master thesis 2017

Ligthart, D. (author)The Ayeyarwady River is a river with large hydrological variations and an abundance of relatively fine non-cohesive sediment, causing the dynamic behaviour of the river with fast shifting channels. This dynamic behaviour, together with the large hydrological variations, is the source of a frequently flooding river with a moderate navigability....master thesis 2017

Tomasoni Speranzini, Belisa (author)This thesis investigates the origins of large sedimentation volumes in the Port of Santos, São Paulo - Brazil. The port is located in the Santos - São Vicente estuarine system, delimited by scarps and subject to intense rainfall. The terminals are placed inside the estuary and their access is provided by a 24 km long channel with mean depths of...master thesis 2017

Velhorst, R.L.C. (author)Morphodynamic models are widespread in coastal engineering practice and indispensable to predict the effectiveness of (large-scale) sandy interventions. These models enable quantification of the effects on enhanced safety against flooding and on environmental impact over time, based on physical processes such as hydrodynamics and sediment...master thesis 2017

Hop, M. (author)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...master thesis 2017

Van Es, H.E. (author)This study aims to improve the predictive capabilities of flow pattern and depositional behaviour of non-Newtonian, high concentration sand and fines mixtures. The depositional behaviour influences the geometry of the deposit and the distribution of sand and fines particles, which in turn influence the strength and consolidation performance of...master thesis 2017

Flierman, M.W.T. (author)River systems are vastly changing environments, not only due to natural process, but also human intervention plays an important role. With the many different river functions at play, large amounts of maintenance budgets are associated with river management. For decision makers it is important to know expected costs or losses and the spread...master thesis 2017

Ton, A.M. (author)The use of the detached offshore submerged breakwater (SBW) for coastal protection has an increasing popularity due to its low aesthetic impact on the natural environment. Submerged breakwaters however have only rarely been adopted and therefore its efficacy remains largely unknown (Ranasinghe et al. 2010). Shoreline erosion has been reported in...master thesis 2017

Vila Santamaria, R. (author)Bangladesh is characterised by its complex river system, which includes the downstream ends of two of the largest rivers in the world: the Ganges and Brahmaputra. Extremely variable flows and fast morphological changes are the principal characteristics of this system, which presents exceptional challenges for river engineering. Distributary...master thesis 2017

Lanters, M.J.C. (author)Coastal zones are extensively used by humans for work, living and recreation. About three billion people live and work within a couple of hundred kilometers from a coastline. In addition the coast is an important breeding zone for marine species. This is also the case at Lake Bardawil. Lake Bardawil is a relatively large lake on the north-west...master thesis 2016

Kala, Y.M.A. (author)The Oesterdam tidal flat nourishment is a hook-shaped nourishment that was constructed in November 2013 in the Kom area of the Eastern Scheldt. One of the objectives of the nourishment is to increase the design life of the Oesterdam in the face of increasing wave loads due to structural erosion of the intertidal flats. A study is conducted in...master thesis 2016

Van Zanten, S.C. (author)The Sand Motor is a unique and dynamic solution for coastal erosion, aimed at distributing the nourished sand along the Delfland coast. Besides enhancing coastal protection, the Sand Motor has been designed to also provide opportunities for recreation and nature development. The contributions of ecosystems to human well-being, that arise from...master thesis 2016

Hekstra, M.A. (author)Mixing systems are used in deep lakes to prevent blue algae from rapidly growing. Air bubbles rise from the bed, dragging water from below upwards. The resulting vertical circulation suppresses blue algae growth. However, these systems demand electricity of about 25,000 per km2 per year. The airlift promises to mix the water more efficiently,...master thesis 2015

Van Schaick, S.J. (author)The overall behaviour of the tide-dominated Western Scheldt is in general well known. Its multichannel-system consists of ebb and flood channels, separated by intertidal areas; the tidal flats. The estuary shows a dynamic behaviour of erosion and sedimentation of the tidal flats. A large flow slide occurred at the tidal flat of Walsoorden in...master thesis 2015

Groenenboom, J. (author)The tide-dominated Scheldt estuary is located in the southwest of the Netherlands. From the Dutch-Belgian border seawards, it consists of a system of channels and shoals and an ebb-tidal delta facing the North Sea. The behaviour of non-cohesive (sand) and cohesive (mud) sediment particles in the area are (until now) generally studied using...master thesis 2015
