Beach development in Oranjestad Bay, St. Eustatius: A study of the morphological system and possible coastal solutions for the creation of a beach

Adank, Karlijn (author)

Sint Eustatius is a Caribbean island located in the north of the Lesser Antilles. The coastline west of the capital, Oranjestad Bay, is of vital importance to the island as it is here where tourism, recreation, the harbour and historical ruins are located. On the other hand, Oranjestad Bay has a heavily fluctuating beach, which is undesirable....

Impact of the Eastern Scheldt Storm Surge Barrier on the Morphodynamics of the Ebb-Tidal Delta: In relation to coastal management

Krikke, Lars (author)

Threatened by rising sea levels and other climate change induced hazards, there is an increased need for coastal flood protection, such as storm surge barriers. However, the construction of such barriers may lead to unwanted coastal changes. This thesis examines the effect of the Eastern Scheldt storm surge barrier on sediment pathways and the...

Design of the navigation and discharge channel in the tidal lake of the Delta21 project: A design and morphological modelling study

van Horick, Quintes (author)

The awareness of climate change has grown worldwide in the past years. Possible consequences of climate change are sea level rise, heavier storms and high river discharges, but also prolonged drought. For a country such as the Netherlands, these water level variations, high discharges and droughts could have a great impact. Therefore, solutions...

The stability of foreland types under dike breach conditions - an experimental study

van der Hagen, Joep (author)

Due to accelerating climate change, which entails more extreme storm conditions and exponential sea level rise, the protective function of our dikes and levees is under growing pressure. The presence of so-called forelands (e.g., beach, mudflat, and tidal marsh) are promising Nature-based Solutions to reduce the probability of dike failure and...

Bayesian downscaling of global bathymetry using spaceborne lidar

Lindsay, Maxwell (author)

Knowledge of nearshore bathymetry is crucial for every aspect of the blue economy. Currently, it is expensive to obtain nearshore bathymetry at regional scales, and therefore this data is not available for many coasts. The data scarcity occurs especially in the global south and big ocean states that are at the highest risk from climate change....

The maximum wind effect on wave overtopping at dikes with crest elements

van der Bijl, Ruben (author)

Climate change affects sea level rise and the safety of the people living behind seadikes. In order to prepare for this, several adaptation measures are available to reduce the overtopping discharge. Wave overtopping can be reduced by including roughness elements or adding a berm. Another possibility is to employ crest elements such as a...

Quantifying complex relations between spit growth and its hydrodynamic drivers, in non-tidal, wind-dominated lake environments: Application to the Marker Wadden (Lake Markermeer, The Netherlands): Spit quantification at the Marker Wadden

van Kouwen, Niels (author)

Many sand spits are morphodynamically complex cases that are hard to quantify. Therefore, most case studies on sand spits in a specific type of environment, are descriptive or even non-existent. As is the case for spits in low-energy lake environments, like the two spits at the Marker Wadden islands. Because quantification is necessary for spits...

Wavepool in a Natural Lake Environment: A Design Study for the Edges of an Artificial Surf Reef in the Noorderplas, Roermond

Gallardo Torres, Victor (author)

Wave surfing is a water sport in which a surfer uses a board to ride a wave towards the shore. It is done in the coastal areas around the globe. Each surf spot has its own wave quality depending on the wave climate and the type of coast. Some spots have year-round perfect waves and other surf spots only work ’when the stars are aligned.’ The...

The potential of dune vegetation during storm conditions: Assessing the applicability of XBeach in dune rehabilitation projects

Heineke, Esther (author)

Coastal protection is required to keep coastal areas protected during storm conditions. Coastal dunes are a natural defense against flooding and erosion from the sea against storms. Many insights have been obtained regarding the positive effects of coastal dune vegetation on dune formation and growth in the past. Several recent studies have...

An experimental study on the drag and inertia forces due to mussel growth on vertical poles exposed to waves

te Velde, Esmée (author)

Mangroves trap sediment and are the first coastal defence line for many coastal areas. Unfortunately, mangrove coasts worldwide are eroding due to deforestation, exposing local communities to flood hazards. In Demak, Indonesia, a Building with Nature approach was chosen to counteract erosion. Permeable dams were built on the foreshore to...

Maximizing the Energy Conversion of a U-Oscillating Water Column in the Low Wave Energy Climate of Gwadar, Pakistan

Ahmed, Azeem (author)

The purpose of this report is to design a wave energy converter, in particular a U-oscillating water column (U-OWC), to maximize energy conversion in the low wave energy environment of Gwadar, Pakistan. At present Pakistan’s 1000km coastline is largely undeveloped and the county is devoid of any wave energy harnessing devices or studies. However...

Thesis small scale equilibria in tidal basins: A data-analysis and case study in the Ameland Inlet

Diepeveen, Bas (author)

The behaviour of tidal basins has been predicted using a modelling approach in which a morphological equilibrium for an entire basin was used frequently in the past. Because tidal basins have, to an certain extend, a fractal nature, it is expected that this approach could be used with a morphological equilibrium for subbasins as well.<br/><br/...

Strength of grass covers on dikes

Boon, Casper (author)

Wave overtopping, in which a wave washes over the crest of a dike and damages its inner slope, is one of the many mechanisms that is found to be responsible for dike failures. As these dikes are generally covered with grass, insight into the erosion resistance of these grass covers against wave overtopping is desired. To assess the performance...

Infragravity wave resonance over coral reef lined coasts

van Noort, Rieneke (author)

Coral reefs are vital to the prosperity of the world and the local communities by providing food and coastal protection. Coral reefs are home to 25% of marine life and have therefore gained the nickname ’rainforest of the sea’. However, the reefs are being damaged by climate change and human intervention, resulting in an alarming rate of...

How tsunami transmission is influenced by floating city design parameters

Geerlings, Simone (author)

For both developed and developing nations, coastal zones form an attractive location for urban settlements. With the expected increase in the earth’s population, coastal areas will experience a further increase of inhabitants. Floating city development could therefore be an interesting alternative for land-based urban expansion on land [41]....

Global mapping of nature based flood risk reduction solutions: A global study on the costs and benefits of nature based solutions compared to conventional hard solutions

Krijger, Tjerk (author)

Coastal flood risk is expected to increase over the 21st century as a result of climate change and economic growth, which makes low-lying regions especially vulnerable. Global screening techniques are needed for a more widespread use of NBS in these flood prone coastal regions. This research expands on the current assessments done by developing...

Hydrodynamic and ecological performance of a new modular unit for living breakwaters: Wave flume experiments and results

van den Brekel, Evelien (author)

Living breakwaters are designed to protect the coast against flooding and erosion, whilst at the same time they enhance the local ecological system by incorporating natural reef components. This study investigates the design of a modular artificial reef developed by the company called Reefy. Reefy breakwaters will consist of interlocking blocks...

Recent analysis on measurements in the North Sea has shown a large amount of wave energy ranging in infragravity bands in the North Sea during storm events. To better understand the generation and propagation of free infragravity waves, the SWAN model is used to inspect the infragravity wave pattern, the infragravity wave origins, and the...
