In this report a design tool has been developed for offshore harbours. The main objective of the design tool is to recommend an optimum value for the offshore distance of the berth, the breakwater length and the breakwater type. This recommendation has to be made based on CAPEX and OPEX estimates for the various structures the offshore harbour...

This study describes the stability of rock on a mild slope (e.g. milder than 1:6) under wave loading. This is done because an increasing number of situations occur where mild foreshores are protected from the wave and currents. The empirical stability formula, designed by VAN DER MEER [1988], is not valid for these kind of slopes. Nonetheless,...

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...

The maximum wave run-up on a beach is an important factor in the design of coastal protection measures. Therefore, it is desired to predict this run-up based on numerical models. In this thesis, this is done with the use of the model XBeach. Wave run-up consists of multiple components: a swash height, S, and a wave set-up, <η>. The swash height...

The United States of America – and more specific the state of Illinois – are dealing with a problem of Asian carps spreading from inward waterways to the Great Lakes. The Asian carp was originally brought to America to be used in study?s on agricultural pounds, but escaped after series of flooding. The Asian carp has no natural enemies in the...

One of the most economically and ecologically important issues related to coastal engineering is the preservation of the coastal areas. The mean to do so, is the good understanding of the sediment transport mechanisms that are involved in the transformation of coasts. In order to protect these valuable areas, man-made structures have been...

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...

Dutch flood protections are assessed every five to six years in a nationwide safety assessment round. During the last assessment round large dike stretches in the Dutch Wadden Sea could not meet the safety requirements, and were assessed with failure. Dike strengthening is therefore needed in these areas. However, in front of these dike salt...

The Netherlands are protected against extreme high waters from the sea by an ingenious system of barriers. One of the most famous ones is the Maeslant barrier in the New Waterway near the port of Rotterdam. This barrier however, is subject to discussion, as it might not function as intended, because of the following reasons. It has a very low...

In this research the reliability of dikes are studied that are influenced by the presence of buildings. Along many Dutch dikes (residential) buildings are present. These buildings may influence the reliability of the dike positevely and or negatively. In this study a probabilistic method is developed to determine the influence of a building,...

Relative sea level rise and climate change, but also the migration of the growing world population to the coast, continuously increase the pressure on the coastal system. In combination with the increased awareness for sustainability, the interests in the coastal zone become integrated and complex. Integrated Coastal ZoneManagement (ICZM)...

The inundation height of the Tohoku tsunami of 2011 exceeded the design levels of many coastal barriers and several structures collapsed. Hundreds of seawalls and breakers are (planned to be) (re)built in the Tohoku district. There is much debate about the conventional tsunami walls and it is therefore suggested to consider alternative tsunami...

Breakwaters with single layer concrete armour are very commonly applied nowadays. Much research is available on the stability of single layer armour units on the seaward slope. However, rear slopes design methods for single layer armour units are rare. On rear side slopes usually similar sized units as on the seaward slope are applied. Limited...

The existence of tidal flat is beneficial for human beings, but it faces the risk of being vanished by continuous intervention, either by nature or human. Therefore, researches about tidal-flat’s morphodynamics are required for the sake of its preservation. Here, the subject of the research is the Kapellebank tidal flat in the Westerschelde...

As part of the Afsluitdijk project the discharge capacity, which is currently facilitated by two sluice complexes, is increased to cope with future sea level rise. It was decided to realise this by an innovative solution: the pump gate. The steel lifting gates, each containing three pumps, will be implemented in the existing sluice complex in...

This thesis investigates the origin of observed current velocities at the Gemini offshore wind farm in 2015. Currents have been measured of 1.2 m/s while, based upon tidal and storm predictions, currents of only 0.7 m/s were expected. The aim of this research is to gain insight into the origin of these higher currents, taking into account the...

In this study, a numerical model (XBeach-vegetation) and statistical Bayesian Network (Netica) was developed for the simulation and quantification of wave attenuation for various combinations of global salt marsh characteristics and extreme hydraulic conditions. The purpose of this modeling effort was to test the ability of the numerical model...

To determine the nominal diameter of armour rock for a rubble mound breakwater, the ‘Van der Meer’-formula is frequently used. It requires the so-called 'notional permeability' parameter P, which has been defined for a limited number of structures. Often designed structures deviate from these defined lay-outs. To determine the notional...
