Doets, I.J.E. (author)Controlling the distribution of water and sediment at river bifurcations is one of the main challenges in river engineering and management. This distribution affects the stability of river bifurcations as well as the distribution of flooding risk, navigability and environmental conditions. The governing factors are the hydrodynamics of the two...master thesis 2015

De Kort, J.G. (author)In 2011 the Sand Motor was realised at the coast of the province of South-Holland as a pilot project combining different functions such as safety, recreation and nature development, following the philosophy of Building with Nature. The idea was to create a mega nourishment that would supply the coastal system between Hook of Holland and...master thesis 2015

Vrolijk, E.F. (author)The world population is growing. Together with the population, the need for resources is growing, as is the need for the transportation of these resources. A significant part is carried out through marine transport, directly relating to the increasing need for port development. All over the world, a shift increasingly occurs towards applying...master thesis 2015

Broekema, Y.B. (author)In this study a modelling approach was investigated that takes into account the effect of short wave grouping on long wave motions, calculating sediment transport and morphology with multiple fractions and a layered bed stratigraphy. After extensive testing and validating this model using data collected in a wave flume in Hannover this model was...master thesis 2015

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

Curto, V. (author)The morphological impact on nourishments of conditions with high oblique wave incidence has been investigated in literature using either a one-line approach or quasy-2D models. These models predict downdrift nourishment migration and the generation of alongshore sand waves for persistent conditions with high oblique wave incidence. However,...master thesis 2014

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

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

Van der Zwaag, J. (author)The sediment composition of the sea bed is of relevance for various coastal properties such as bed forms, beach slopes and marine ecology. Furthermore it may significantly influence the morphological evolution of the coast. Knowledge about the processes forcing the spatial distribution of a certain grain size is therefore of great importance....master thesis 2014

Stam, G.N. (author)Recently, nourishments have been carried out on a large scale to counteract the on-going erosion along the Dutch Coast. The main advantage of these large beach extensions is that large stretches of coastline are protected for a long time scale (e.g. 20 years), which decreases the frequency of nourishing significantly. This is not only cost...master thesis 2014

Van Velzen, B.J.M. (author)An offshore terminal is proposed to be constructed adjacent to the entrance of an Estuary in the Niger Delta. A dredged approach channel of around 10 km long, 250 m wide and to a depth of -14 m LAT is required to allow ships to reach the terminal. From earlier research it is found that high transport rates of fine sediment, in the order of 10...master thesis 2014

Van der Biezen, T.F. (author)Historically, the coastal zone has always attracted people and across the globe the benefits of inlet systems have made communities settle there. The Tu Hien inlet and the Tam Giang–Cau Hai lagoon system in Vietnam are no exception, as approximately half a million people depend on it for their livelihood. Tidal inlets are also known for their...master thesis 2014

Vrolijk, E.F. (author), Poelhekke, L. (author), Schlepers, M.H. (author), De Boer, G.G. (author)In the North of Cuba, the Oasis beach area is situated. The beach suffers from structural erosion and earlier measures to deal with this have not succeeded. In this project, a solution is offered to reach two goals: foremost, a beach improvement to the Oasis beach sector and second, a halt to the structural erosion in the sector in order to...student report 2014

Visser, P. (author)After decades of coastal erosion in the north-west area of the Island of Texel, the shore-normal `Eierlandse Dam` had been built in 1995. The dam, situated in the outer delta of the Eierlandse Gat tidal inlet, resulted in a remarkable short-term morphological development of the adjacent coast. Four years following completion of the dam, large...master thesis 2014

Attema, Y.H. (author), Hendriks, H.C.M. (author)In 2013 and 2014, a hydrodynamic model for the Ayeyarwady delta was developed. This delta is located in the Southwestern part of Myanmar. Because it is prone to flooding and is also affected by salt intrusion during periods of low river discharge, it was chosen to develop a hydrodynamic model to gain more insight into the aforementioned...student report 2014

Van der Baan, A.L. (author)Shore-parallel submerged breakwaters (SBWs) appear as an attractive form of coastal protection. Compared to their emergent counterpart there is no impact on the beach amenity and aesthetics. In addition, there is a possibility for recreational purposes. However, the actual application of SBWs is often discouraged because the complexity of the...master thesis 2013

Van Cuyck, T.A.P. (author)De ecologische kwaliteit van het Markermeer is de laatste decennia sterk achteruit gegaan. De oorzaak hiervan is dat door de afsluiting van het Markermeer met de Houtribdijk een ondiep meer is ontstaan met een bodem van klei waarin een dynamische sliblaag aanwezig is. Al bij lage windsnelheden ontstaan golven die erosie van deze sliblaag...master thesis 2013

Kaji, A.O. (author)The objective of this thesis is to investigate the role of different hydrodynamic and morphological factors influencing sediment transport patterns at the Sand Motor in order to give insight in processes controlling the short-term sand bar morphodynamics and the long term development of the Sand Motor. The work presents an analysis of the...master thesis 2013

Stengs, B. (author)Recently an unstructured version of Delft3D, named D-Flow FM, has been developed at Deltares. This tool shows high potentials for coastal modelling due to the flexibility in domain resolution and unstructured grids. This MSc thesis focussed on implementing wave effects in D-Flow FM with satisfying results. In addition, a coupling system is built...master thesis 2013

Luteijn, J.M. (author)Problem definition The city Mar del Plata has one of Argentina's largest ports and biggest seaside beach resort. After the construction of the port, a steadily growing sandbank appeared in the port entrance and considerable erosion occurred on the northern beaches. To warrant the accessibility of the port, frequent maintenance dredging is needed...master thesis 2013
