Leenders, Sjoerd (author)The growth of the offshore wind industry results in intensive usage of the sandy seabed in the North Sea, currently and in the coming decades. Large-scale bed forms are present in shallow seas with sandy beds such as the North Sea. The most dynamic bed forms are sand waves. Due to their dynamic behaviour, sand waves can interact within offshore...master thesis 2018

Keulers, Bob (author)The typically mild slopes of the muddy coastline in the south of Myanmar, enable the tide to propagate deep into the mainland, carrying muddy and saline water. The Nga Moe Yeik Creek (a tributary of the Yangon River) is closed off at the upstream end during the dry season and is subject to high siltation rates. Extensive dredging is necessary to...master thesis 2018

van den Berg, Ileen (author)The Xbloc<sup>Plus</sup> is a new type of single layer armour unit for breakwaters. The key difference between earlier single layer armour units is that the unit is not only placed in a regular grid, but also with a regular orientation. The main benefit of this is that it can directly be seen whether the unit is placed correctly. Additionally,...master thesis 2018

Rijper, Huub (author)This thesis discusses the morphological modelling of the gravel revetment on artificial composite beaches. A composite beach is a combination of a sandy lower beach and a gravel upper beach. These beaches are found in nature, but can also be created artificially by placement of a gravel structure on a sandy beach. Artificial composite beaches...master thesis 2018

van Bemmelen, Cas (author)Beach scarps are nearly vertical seaward facing walls within the cross-shore beach profile. These features are often associated with eroding (nourished) coastlines and can reach heights of O(2-3 m), leading to serious hazards to beach users and negatively impacting local ecosystems. New insights into beach scarp morphodynamics related to...master thesis 2018

Klaver, Sebastiaan (author)Many small island developing states (SIDS) are among the most vulnerable to climate change (e.g. sea level rise) and seasonal to inter-annual climate variability, and subsequently experience flooding due to swell waves and wind waves, coastal erosion and salinisation of freshwater lenses. To counteract this, reef flat mining for sand and...master thesis 2018

Simonse, Jesse (author)Since 1990, the Dutch coastline is maintained within the ‘Dynamic Preservation’ program, according to which the coastline is maintained seawards from a reference line, mainly by applying nourishments. Research into the maintenance of the Dutch coast is continuous and causes the content of the coastline preservation program to change constantly...master thesis 2017

van der Zee, Wessel (author)Flushing basins have been used at several locations in Germany, Belgium, and the Netherlands in the past centuries to maintain the navigational depths of harbour channels. These locations are not in use anymore or are only partly responsible for channel maintenance. This thesis encompasses a study to optimize the geometric parameters of a...master thesis 2017

Roest, Bart (author)The Sand Engine is a new innovation in coastal protection, a mega feeder nourishment. This pilot project was constructed in 2011 along the Delfland coast, which is historically prone to erosion. Since its construction, the Sand Engine is intensively being monitored to track the morphological development.<br/><br/>The objective of this thesis is...master thesis 2017

Kar, Attman (author)Across the world, the presence of humans in coastal regions is always increasing. Hydraulic forcing from extreme events is a large risk around the global coastlines, the risk being complicated by the increased human presence along the coasts.<br/>The knowledge that vegetation can be used as a coastal protection measure is not something new. The...master thesis 2017

Vos, Amber (author)In this MSc thesis it is investigated how the first version of concrete armour unit Xbloc<sup>+</sup>, Xbloc<sup>+ v1</sup>, acquires its stability. The stability mechanisms are investigated by conducting two type of physical model tests. First, 23 dry pull-out tests are done to obtain insights into the aspects and mechanisms that influence the...master thesis 2017

Von Gronau, Clemens (author)With the implementation of new legal aspects for dune safety assessment in 2017, the current method, Duros+, is no longer feasible to represent the desired processes. This 1D deterministic, volume-balance model cannot simulate processes like inundation and overwash, which are crucial to fulfil the new requirements for dune safety assessment....master thesis 2017

Bart, L.J.C. (author)XBeach is a process-based morphological model that has been used for modelling short term behaviour of beaches and dunes. In the past years interest has been shown by researchers and engineers to use XBeach for longer simulation periods (multiple years). XBeach has multiple modules: stationary mode is often used during calm conditions and...master thesis 2017

Horst, J. (author)Coastline regression is a significant threat to many coastal zones. Being able to mitigate the erosion while simultaneously improving nature development is something that is increasingly strived for in coastal projects. This report utilizes the building with nature philosophy to explore integrated solutions for a coastal erosion problem in...master thesis 2017

Rada Mora, Belen (author)In recent years, the use of Xbloc units has increased exponentially. However, the placement of this unit is not always done as randomly as it should be and consequently, the stability of the armor is affected. In order to overcome this problem, Delta Marine Consultants is developing a new armor unit called Xbloc+ that has a regular placement. In...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

van Ekdom, K. (author)The objective of this research is to contribute to the understanding of the morphological behaviour of a sandy foreshore in the Markermeer, along the Houtribdijk. The research is primarily based on monitoring data obtained from the Building with Nature (EcoShape) project “Pilot Houtribdijk”. The focus is on the morphological development of the...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

Geerlof, R.W. (author)This document describes a study into the influence of alongshore bathymetric variability on currents which form a risk to bathers. Changes to coastal zone management along the Delfland Coast have given rise to questions on the influence of alongshore bathymetric variability on bather risk. Extensive measurement data is available from two...master thesis 2017
