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

Knaack, W. (author)Een onderzoek naar de morfologische veranderingen in het Friesche Zeegat. Na de afsluiting van de Lauwerszee is het bekken continu in verandering. Dit heeft gevolgen voor de bevaarbaarheid van de vaarroute naar Schiermonnikoog. In dit onderzoek wordt een voorspelling gedaan naar de ontwikkelingen voor het komend decennium en de gevolgen van deze...master thesis 2009

Hanegan, K.C. (author)In this study, a process-based, depth-averaged Delft3D hydrodynamic and morphologic model of the Wax Lake Delta in Atchafalaya Bay, Louisiana was developed to simulate a five year period of delta development. The purpose of this modeling effort was to test the ability of process-based modeling tools to successfully simulate typical delta...master thesis 2011

Bos, M.F.M. (author)The wetlands in the Mississippi delta (USA) are drastically subsiding and eroding. Many projects and researches are ongoing to determine how this “drowning effect” of the delta can be stopped. One of the solutions that could be feasible is implementing sediment diversions in the levees of the Lower Mississippi River in order to divert sediment...master thesis 2011

Future and current sea dike reliability analysis under severe storms in Shanghai Pudong New DistrictLu, Bingjing (author)Shanghai sea dikes are built to protect shorelines, factories, inland buildings and other vulnerable coastal areas against wave action and storm surge. For this reason, there is an urgent need to check whether sea dike in Shanghai can function well. The intuitive influences are sea level rise, severe storm surge, and land subsidence, which...master thesis 2020

Van Son, S.T.J. (author)Coastal monitoring: Bathymetric surveys of an area of 1 square kilometer of the shoreface near Ter Heijde have been perfomed using the NEMO Jetski. Instruments installed are a Single Beam Echo Sounder (SBES) for depth measurements and accurate GPS for positioning (RTK-GPS). The quality of the Jetski as a platform for bathymetric surveys has been...master thesis 2009

Jiao, J. (author)The Dutch Wadden Sea is consisting of 7 tidal inlet systems separated by sandy barrier islands. The general morphodynamics and hydrodynamics of tidal inlets are relatively well understood, but the detailed interactions remain a prominent research interest. In this study, process-based computer models are employed as a tool to investigate the...master thesis 2014

Schlooz, G. (author)This study investigates the hydrodynamics at a convex coastline. The Sand Engine, a man made peninsula in the Netherlands, is used as a case scenario. It is hypothesized that a rip current can develop under certain wave conditions due to the change in coastline orientation. The main goal of this research is to obtain a better understanding of...master thesis 2012

Den Boer, V.J.E. (author)The Langmann reservoir is part of the hydropower system in the river Teigitsch and in the reservoir loss of storage volume occurs. The reservoir was therefore flushed, but recently no permission is granted. The reason is the high sediment concentrations that have negative effects on the downstream region. An optimization of the flushing...master thesis 2011

van Maanen, Remy (author)The People's Republic of China experienced large socio-economic development over the last decades, which was mainly concentrated in coastal regions. Jiangsu Province is among these regions, which shows large socio-economic differences between north and south. The Chinese Central Government has allocated Binhai County as a new coastal development...master thesis 2020

Kosters, Anna (author)Like many rivers around the world, the Loire river in France has a history of human interventions in order to facilitate navigation and port development. Next to affecting bed levels directly, the heavy modification of the river-estuary has induced significant changes in the hydrodynamic and morphodynamic behaviour of the Loire. As a result, the...master thesis 2019

Tuinhof, T.J. (author)By its very nature dredging is an environmental impact, since dredging includes the excavation and/or relocation of sediment in a river, sea or estuary. One of the environmental impacts related to dredging is increased suspended sediment concentration (SSC) levels, forming plumes of sediment. These so called dredge plumes originate from spillage...master thesis 2014

Scheel, F. (author)Tidal inlet systems, as found in the Dutch Wadden Sea, often feature both sand and mud. Due to differences in sediment properties, sand and mud particles respond different to identical forcing conditions, like short waves and tidal currents. Because of this, sand and mud can get transported to different locations. This process is referred to by...master thesis 2012

Hasselaar, R.W. (author)The numerical flow model Delft3D simulates the flow of water and movement of submerged sediment by means of solving simplified equations that describe these processes. Because of these simplifications, parameterizations are introduced. These parameters represent amongst others the processes that take place on scales smaller than the spacing of...master thesis 2012

Hoogduin, L. (author)The aim of this research is to determine to what extend the scour holes limit the sediment transport through the Eastern Scheldt storm surge barrier and whether or not human adaptations, like sand-nourishments in the scour holes, can have a positive effect on the sediment import. To investigate these scenarios a numerical model (Delft3D) is used...master thesis 2009

Arailopoulos, I. (author)Depth-averaged morphological computations using Delft3D tend to produce ‘strange’, results for river bends when the sediment transport formulas of Van Rijn are used. Even pools in inner bend regions and bars in outer bend regions can result from the model. The objective of the present thesis is to identify the cause of the problem and propose...master thesis 2014

Commandeur, A.S. (author)Turbidity currents are major transport agents in reservoirs in which high concentrations of fine sediments flow in. Reservoir sedimentation due to turbidity currents is often severe in these cases. Turbidity currents are not well understood due to their complex turbulent flow structure, the interaction between the flow with the particles and the...master thesis 2015

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
