Meijer, Theo (author)The dunes along the Dutch coast serve as a critical component of flood defense. Storms and a shortage of sediment supply offshore lead to dune and shoreline erosion, posing a hazard to flood safety. To combat coastal erosion, the Dutch government decided in 1990 to proactively nourish the coast. It is expected that as an indirect effect of the...master thesis 2023

Nieuwhuis, Thomas (author)When two storms quickly succeed one another, it can be called a twin storm. Storm conditions at the coast can lead to higher water levels and waves that can give rise to dune erosion. Therefore, after a storm the dunes are smaller than before the storm. Dune accretion is a much slower process than dune erosion; it can take weeks to months of...master thesis 2023

Cuevas Salgado, Sebastian (author)Coastal dunes serve as the primary defence mechanism against coastal storms for many coastal communities around the world. Vegetation plays a role in increasing dune resiliency as it enables dune growth, however not enough is known about its effects during storms. Research has shown that the current climate crisis will increase the intensity of...master thesis 2023

van Manen, Menno (author)The Netherlands is a country with a history of human activity along the coast to ensure water safety. In the 1990's a new approach to coastal management was adopted that allowed for more experimentation in the Dutch dunes. Since then a slew of different types of projects have been undertaken, one of which is the construction of foredune blowouts...master thesis 2023

de Hullu, Cato (author)Along the Dutch coastline, coastal dunes act as the primary sea defence to protect the low-lying areas behind it from flooding. To ensure that these dunes are strong enough to meet national safety standards, models are used to assess their strength. Even though our modelling capabilities have significantly improved over the years, model...master thesis 2023

Labaar, Anna Lisa (author)For European Union member states, it is mandatory to assign Natura 2000 areas and regularly monitor them. Currently, vegetation mapping is done mainly manually, which is a time-consuming and expensive practise. Unmanned Aerial Vehicles (UAVs or drones), manoeuvrable vehicles with which high-resolution measurements can be done, could increase...master thesis 2022

van Kessel, Bart (author)Dunes are the primary sea defence along the Dutch coast. This research investigated the development between 1965 and 2021 of the beaches and dunes of the Hoogheemraadschap Hollands Noorderkwartier (HHNK) area which stretches from IJmuiden to northern Texel. This research used an advanced data analysis on the annual coastal elevation data. The...master thesis 2022

Roor, Twanne (author)Coasts are constantly under the pressure of hydrodynamic conditions such as waves, tides, and storms. In the Netherlands, sand nourishments are executed every few years in order to maintain the country’s sandy beaches for purposes of safety, recreation, and ecology. In order to determine where to carry out these nourishments, the whole sandy...master thesis 2022

Krijnen, Inelotte (author)In future decades, coasts will be exposed to increasing risks because of climate change and sea level rise, which poses an increased threat of coastal inundation, erosion and ecosystem loss. The natural variability of coasts can make it difficult to identify these impacts. Most beaches worldwide show evidence of recent erosion. Sea level rise is...master thesis 2021

Coastal Aeolian Sediment Transport in an Active Bed Surface Layer: Tracer Study and Conceptual ModelUphues, Charlotte (author)Coastal aeolian sediment transport is influenced by supply-limiting factors such as sediment sorting by grain size. Sorting processes can cause a coarsening of the bed surface and influence the formation of aeolian ripples. However, it is not fully understood what influence sorting processes have on the magnitude of this transport. In this study...master thesis 2021

Scheijmans, Jasper (author)The Netherlands has 254 km of coastline that is covered with sandy dunes. As these dunes function as primary flood defences, intensive research has been conducted into dune erosion in recent years. This research mainly took place in laboratories, because all boundary conditions could be controlled and measurements could take place very...master thesis 2021

Zwarenstein Tutunji, Nicha (author)This thesis describes the development and the characteristics of the coastline along the Dutch coastal zone, managed by Hoogheemraadschap Hollands Noorderkwartier. The coastal zone is a rich environment with multiple stakeholders. These stakeholders use the coastal zone for a range of functions such as safety, nature, business, and recreation....master thesis 2021

Liqui Lung, Frans (author)In this paper we introduce a setup to investigate aeolian saltation and surface dynamics on a centimetre spatial resolution and a sub second temporal resolution. We develop a Lagrangian saltation model and a high-resolution surface model, which we couple to each other and to a turbulence resolving large eddy simulation model. The simulated...master thesis 2020

Kras, Etienne (author)Today's coastal zones are densely inhabited as the majority of the world's population lives in these attractive areas. The shorelines in coastal zones are shaped by complex spatial and temporal variable interactions between natural forcings like changes in mean sea-level, tides, wave and wind conditions, and storm surges. Besides, natural...master thesis 2019

Rodriguez Galvez, Luis (author)Galveston Bay is an area in the Upper Texas Coast (USA) historically suffering from the impact of several large magnitude hurricanes. In 2008 hurricane Ike, one of the most devastating natural disasters in Unites States recent past, raised awareness of the flood vulnerability problem of the area and triggered the beginning of different proposals...master thesis 2019

Mann, Mathijs (author)The port of Rotterdam was full and new mooring locations were required to host the largest ships in the world. And if there’s no space to expand on land, why not create land in the sea? That is exactly what The Netherlands did by creating Maasvlakte 2. The construction of Maasvlakte 2 started in 2008 and was officially completed on May 22nd ,...master thesis 2019

van der Graaf, Onne (author)'De Slufter' is a nature conservation area located in the Northwest of the Dutch Wadden island Texel which is inundated with seawater during storm events. The landward side of De Slufter is a sand dike which is part of the primary coastal defence ring of the island. HHNK, which is responsible for the coastal safety of Texel, currently relocates...master thesis 2019

Fortuijn, Lars (author)In 2003, it was established that the sea dike between Petten and Camperduin was insufficiently safe.<br/>To ensure the safety of the hinterland against flooding, this part of the Dutch sea defence system needed to be strengthened.<br/>During the design process, the most favourable variant was to construct a dune and beach system in front of the...master thesis 2018

Verschuur, Jasper (author)Sandy beaches comprise large parts of the world's shorelines and act as a natural buffer for many exposed people and assets that are concentrated in the coastal zone. Many coastal communities are vulnerable to the impact of sea-level rise (SLR) that can amplify the episodic erosion from storms and drive structural erosion. The way communities...master thesis 2018

Wang, Nan (author)Coastal zones all over the world have become heavily populated and developed due to the aesthetic value and diverse ecosystem services that they provide (Luijendijk et al. 2018). In recent years, however, climate change and anthropogenic pressures have exacerbated unprecedented coastal recession, threatening billions of dollars’ worth of coastal...master thesis 2018
