Bodde, W.P. (author)
Coral reefs are highly valuable structures in many respects and it is increasingly important to understand hydrodynamics and morphodynamics around reefs to be able to better protect them and their hinterland. Flume experiments were performed on a scaled fringing reef in the laboratory facilities of Deltares in Delft. The objective of this thesis...

De Kort, J.G. (author)
In 2011 the Sand Motor was realised at the coast of the province of South-Holland as a pilot project combining different functions such as safety, recreation and nature development, following the philosophy of Building with Nature. The idea was to create a mega nourishment that would supply the coastal system between Hook of Holland and...

De Vries, B.B. (author)
During a storm dunes erode and provide sediment to the beach. The foreshore rises and the wave height decreases. Subsequently the wave-induced water level setup increases. Seawalls do not erode. The waves in front of the seawall remain high throughout the storm and the wave-induced water level setup hardly changes. Over a dune-dike connection a...

Although mangrove forests have proven to contribute to wave dissipation significantly, these ecosystem are threatened mainly by the expanding aquaculture. International or nationwide applied greenbelt policies are often used for the preservation of the mangroves and hence the flood hazard reduction, without taking local (hydrodynamic) conditions...

Pomeroy, A.W.M. (author)
Reef systems have been estimated to exist along approximately 80% of the world’s coastlines with living coral reefs, relic limestone platforms and submerged rock formations being the most common types observed. The processes of wave breaking on a reef crest, setup on a reef and flow over and within a lagoon, have been the primary focus of...

Winter, G. (author)
Rip currents are narrow, seaward directed flows in the surf zone that can pose a serious threat to swimmers. This issue has received attention particularly on swell dominated coasts (such as the US, Australia, France and UK) where numerous field experiments have been undertaken. However, the threat of rip currents is less recognised on wind-sea...

Gawehn, M.A. (author)
Coral reefs are hard structures that front many coasts in tropical and subtropical climates and protect them against wave attack and erosion. Despite reducing incoming wave energy by up to 98%, coral reefs are not a guarantee that mainland or island coasts are safe from being flooded. This was demonstrated by a series of wave-driven flooding...

Kroon, M.E.N. (author)
Natural reefs are important habitats for a wide range of species. Furthermore, they attenuate waves and thereby protect the leeside, functioning as coastal protection. Many reefs are however eroding or degraded, leading to a loss of these ecosystem services. Artificial reefs can reverse this negative trend. The artificial reefs in this context...

Van Rooijen, A.A. (author)
The swash zone is the part of the beach that reaches from the limit of wave run-up until the limit of wave run-down. It is recognized as being a dynamic area of the nearshore region, characterized by strong and unsteady flows, high turbulence levels, large sediment transport rates and morphological changes on a small timescale. Due to the...

Hurricane Sandy (2012), which made landfall in New Jersey on October 29th, made devastating impact on the East Coast of the USA and struck major parts of New York City, including the economic centre of Manhattan. The total damage (in the USA and Caribbean) is in excess of 100 billion US$ with estimates ranging between 78 and 97 billion US$ for...

Voukouvalas, E. (author)
The storm surge early-warning system that is going to be established in the Netherlands, combines the accurate weather forecast with the hydrodynamic and morphodynamic models in an operational mode, in order to estimate the potential impact on the coasts. This study focuses on the morphodynamic validity of the operational model system, by...

Riesenkamp, M.J. (author)
The long series (>30 year) of measurement data of erosion events at Narrabeen beach (NWS, Australia) provides insight in erosion volumes and their return periods in this area. The aim of this study was to replicate these data using XBeach in order to assess the validity of both the Joint Probability Model (JPM) and XBeach on beaches such as...

Sasso, R. (author)
Rip currents are seaward directed flows of water that traverse the surf zone, and in many cases pose potentially dangerous conditions for swimmers and beach users. The present study is carried out focusing on Perranporth beach, UK, which is known to present quite strong rip current events that have been the culprits of large numbers of incidents...

The Santo André Lagoon is one of many inlets and lagoons that can be found along the along the Atlantic coast of Portugal. These coastal systems have a large ecological value and are important for rich biodiversity. The Santo André Lagoon is part of a natural reserve that is officially under protection of the country. It has a rich flora and...

Oosterlo, P. (author)
In this thesis, a method was developed, with which the infragravity waves and morphological changes of a sandy foreshore are included in the calculation of the probability of dike failure due to wave overtopping. Constructing a natural foreshore in front of the dike can be an attractive and innovative method to decrease the failure probability....

Kolijn, D.J. (author)
The following research focuses on artificial underwater structures (a.k.a. artificial reefs) in a coral reef environment to mitigate the natural and anthropogenic pressures which reef systems are increasingly facing worldwide. The research question is stated as: “Establishing a method to determine if a multipurpose artificial underwater...

Pearson, S.G. (author)
Low-lying tropical islands are highly vulnerable to the effects of sea-level rise and climate change. Most pressing is the threat posed to their fresh water supplies by wave-induced flooding. This thesis attempts to generalize previous site-specific studies of flooding on coral atolls and apply it in a framework that can be used for early...

Jager, T. (author)
This thesis investigates the governing generating mechanisms, shoaling and reflection behaviour of infra-gravity waves on a mild-sloping, macro-tidal, rocky shore platform. The methods comprise among others, field data analysis of the Lilstock platform, numerical modelling using a calibrated XBeach model and a cross-correlation analysis to...

On the south-west coast of Namibia, diamonds were trapped during the Quaternary on bedrock platforms and in bedrock gullies. These were formed by differential erosion due to wave action. The diamonds originated from Kimberlite diamond pipes within the catchment area of the Orange River in South-Africa and Botswana. This river eroded the diamonds...

Poelhekke, L. (author)
Recent and historic events have demonstrated the European vulnerability to coastal floods. Larger and more extreme events in Asia and the Americas have shown the devastating effects that these low-frequency high-impact floods can have. This thesis contributes to the development of an Early Warning System (EWS) for marine coastal hazards. The...
