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...

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....

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...

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...

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...

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...

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...

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...

Pathogens are present in our urban water system, and may pose a health risk to swimmers and playing children. Although the knowledge of pathogens has increased over recent years, little is known about their behaviour in the urban water system. The goal of this thesis is to investigate this. First, the behaviour of pathogens under the influence...

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...

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...

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...

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...

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...

The Mekong Delta is located in the South of Vietnam, where the Mekong River flows into the East Sea. The Mekong Delta is responsible for producing half of the national food volume for Vietnam. Socio-economic and agricultural development in particular, have encountered several restrictive factors though: decreasing amount of agricultural land,...

With the development of a process-based model (Delft3D) of the St Lucia Estuary inlet, a first approach is made with regard to the estuary mouth dynamics and closure mechanisms that are observed at St Lucia inlet. The purpose of this thesis is to get a better understanding of the hydrodynamic and morphological behaviour of the St Lucia inlet...

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...

After the storm surge of 1953, the Dutch Delta project was initiated in order to protect the southwestern part of The Netherlands. A storm surge barrier in front of the Oosterschelde and various dams at the back of the estuary were constructed. These interventions led to a large change of the hydrodynamics of the Oosterschelde: a large decrease...

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...

Property development along the west coast of Barbados has led to an increasing pressure on the coastline as property owners desire to have their residences close to the sea. The addition of new coastal structures including revetments, breakwaters, and groynes, changes the dynamics of the natural littoral system. The sediment transport mechanism...
