Verbruggen, W. (author)Local geometrical perturbations in alluvial channels can generate a pattern of alternate bars. Each bar is accompanied by a pool at the other side of the channel. This pool can decrease the strength of the bank, which can result in bank failure and bars can hinder navigation. Furthermore, non-migrating alternate bars are considered to be a...master thesis 2012

Irving, Meghan (author)Flexible river training structures such as tetrahedron frames (`porcupines') can be attractive for control of braided river channel networks in regions where permanent control structures (e.g. groynes or dams) are too expensive or potentially inefficient, such as systems with highly dynamic flow regimes and morphology. Porcupines provide...master thesis 2020

Vlijm, R.J. (author)Submerged breakwaters (SBWs) are becoming increasingly popular as alternative coastal defence system due to the lack of impact on beach amenity and aesthetics compared to common emerged beach protection measures. However, the recent significant amount of failing SBWs resulting in additional shoreline erosion reported in [Ranasinghe and Turner...master thesis 2011

Vacek, Matt (author)Traditional reservoir modelling utilizes a stochastic approach centered around statistics to generate a 3D representation of the reservoir. While the results of a stochastic approach are favorable, they tend to lack the detail that is necessary to fully understand the different aspects of the reservoir, more precisely, the inclusion of...master thesis 2018

Bode, Danielle (author)Predictions of the morphology of coastal areas are used to make decisions on coastal defence and nature conservation. To predict this morphology, simulations made by morphological models are used. To base decisions on this morphology predictions, we want the uncertainties in these predictions to be small. The goal of this research is to get a...master thesis 2020

van Utenhove, Erik (author)As a result of the unabated growth in plastic usage worldwide, their abundance in the marine environment has steadily increased over the last few decades. Nowadays, plastic litter is observed across all oceans and shores. Due to their wide spread and adverse effects on ecology, economy and potentially human health, plastic pollution has been...master thesis 2019

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

Zimmermann, N. (author)The Westerschelde estuary in the South-West of the Netherlands displays two meandering flood and ebb channels separated by shoals. The system of flood, ebb channel and shoal between two channel crossings form a morphological cell. The stability of the serial cell system formed by the Westerschelde is important for the navigation route to the...master thesis 2009

Tromp, R.L. (author)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,...master thesis 2013

Hoist the flag: A boundary rip current case study on swimmer safety in the Scheveningen harbour areaMustafa, Asor (author)Each year several fatalities due to rip currents are reported in the Netherlands. One of these accidents was during May 11th in 2020 near the Scheveningen harbour, were several surfers lost their lives. During the hydrodynamic and meteorological accident were quite severe, with a significant wave height of 3.0m and wind speeds of 11 m/s, which...master thesis 2021

Van der Linde, P. (author)During the fall of 2003, an extensive measurement campaign called the “Nearshore Canyon Experiment” (NCEX) was set up along the coast of La Jolla, California. The project site covered an area in which two submarine canyons are located, respectively La Jolla and Scripps Submarine Canyon. Over 20 institutions collaborated on recording the...master thesis 2010

Groenewegen, Maurits (author)The Bollen van de Ooster, in this report referred to as the Ooster, is a sand bar in the outer delta of the Grevelingen. The Ooster is separated from the coast by a relatively deep channel, called the Schaar. Closure of the Grevelingen in 1971, with the construction of the Brouwersdam, initiated vast changes in morphology. Damming of the estuary...master thesis 2019

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

Monclus Abadal, Albert (author)Sandy barriers comprise 12% of coastlines around the world, and most of these barriers enclose tidal bays and lagoons. These systems accommodate human settlements vulnerable to climate change, which offer enough economic, social, and environmental utility to require further research on the impact of climate change and subsequent best management...master thesis 2018

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

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

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

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

Bregman, Martijn (author)This thesis presents a new methodology for representing the effect of spiral flow on the bed shear stress magnitude and direction, using a low-vertical-resolution three-dimensional model. Furthermore, it discusses the performance of the new methodology in comparison with conventional high-vertical-resolution three-dimensional and depth-averaged...master thesis 2018
