Gootjes, G. (author)
Due to natural processes, such as tides and waves, the coastal area is continuously changing. Process-based morphodynamic area modelling is one of the relatively new tools to predict these changes in the coastal area. One of these process-based models is Delft3D-MOR, developed by WLIDELFT HYDRAULICS. However, computations on a long time-scale...

Bakkenes, H.J. (author)
When a field of short wind waves is observed, it can be seen that a slow variation in amplitude of these waves take place. Due to this amplitude variation, waves are generated with a similar time scale as this amplitude variation. These second order waves are associated in literature with the terms as surfbeat, bound waves or forced infragravity...

Van Giffen, I.K. (author)
This master thesis project focusses on the numerical modelling of bound and free long wave action in two diffrent harbours. This model, called Surf Beat, is a time dependent generic numerical model for the simulation of generation and propagation of bound long wave energy generated by short carrier waves. This model has been developed by Delft...

Van Noorloos, J.C. (author)
The present report describes a laboratory study on energy transfer between short wave groups and bound long waves. From previous experiments (Battjes et al. (2003) the bound wave travelling shoreward is observed to grow faster than Green's Law, indicating that the bound wave gains energy from other spectral components. Under certain conditions,...

This thesis describes a numerical study on identifying parameters controlling the shoaling rate for the normally incident low frequency motion and the long wave reflection in the coastal zone.

Daly, C.J. (author)
It has been found by many researchers that low frequency (LF) waves dominate the wave energy spectrum in very shallow water. Given that many longshore and cross-shore morphological processes are located within this zone, LF waves play an important role in determining morphological change, especially dune erosion and overwash during storm events....

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...

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...

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...

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...

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...

Den Bieman, J.P. (author)
Barrier islands are important features in the coastal zone, among others because they shelter the mainland from waves and storm surge. Thus, the degradation of barrier islands can pose a threat to coastal safety. Hence, there is a societal demand for understanding and predicting barrier island evolution. High energy events, such as storms and...

Morris, J.C. (author)
Our understanding of nearshore coastal zone processes can be improved significantly with the availability of high spatiotemporal resolution bathymetry data. This high resolution data can be used for validation and calibration of numerical models, for providing forecasts of hydrodynamic conditions and morphological development, and for monitoring...

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...

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...

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...

Nederhoff, C.M. (author)
Many of the most densely populated areas are located near the coast. Climate change and population growth put more and more pressure on these coastal areas. As free space is becoming sparse, coastal disaster risk reduction plans need to be spatially efficient. In this thesis the sandy coast with hard structures, such as buildings or dune...

The aim of this research was to take the first step in understanding the wave runup process on an atoll reef using the XBeach model. Field data collected from 3 November 2013 to 13 April 2014 at Kwajalein Atoll in the Republic of the Marshall Islands was used. The dataset included data on bathymetry, waves, water levels and wave-induced runup....

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...
