Morphodynamic models are widespread in coastal engineering practice and indispensable to predict the effectiveness of (large-scale) sandy interventions. These models enable quantification of the effects on enhanced safety against flooding and on environmental impact over time, based on physical processes such as hydrodynamics and sediment...

After the Deepwater Horizon oil spill in 2010, oil was released into the Gulf of Mexico and partly reached the shorelines. Here, it mixed with sand in the surf zone to form sand and oil agglomerates (SOAs). These cm-sized particles are heavier than water and are therefore found on the seabed. Years after the initial formation of these particles,...

Around the world, areas with unique ecosystems are prone to harmful factors deteriorating their environment. Management of these areas need knowledge on the ecological status of these areas, to make decisions for future problems. They need easily accessible information on indicators describing the conditions of these areas. Obtaining this...

Wave climate in harbours determines for a significant part the efficiency of harbour operations. A good prediction of the hydrodynamics is therefore regarded as indispensable, which is often done by means of advanced numerical modelling. This study is a part of the Joint Industry Project XBeach. The goal of this research is to determine the...

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,...

The determination of wave penetration in ports is of great importance for the design of coastal structures and for the efficiency of port operations. Nowadays, coastal engineers can make use of numerical models for the assessment of wave climates in ports. Various numerical models exist, including the phase resolving models SWASH (TU Delft) and...

The present thesis considers numerical computations of fully nonlinear fluid-structure interaction. The aim of the thesis is to establish a well validated fully nonlinear numerical wave tank for the simulations of complex fluid-structure interaction of moored floating offshore structures. The numerical computations are carried out using the...

Since their development in the 1970s, mesoscale atmospheric models have been used for a variety of meteorological applications. Over the years, the models have evolved and nowadays, state-of-the-art atmospheric models are capable of operating on spatial resolutions in the order of kilometres. In the hydraulic engineering community, atmospheric...

Alongshore currents are currents parallel to the coastline. In coastal areas they are driven by a combination of wave and tidal forcing. In this study, the validity of the non-hydrostatic, wave-flow model SWASH to predict these currents is investigated. This is done by comparing model predictions with measurement observations. Observations were...

Mixing systems are used in deep lakes to prevent blue algae from rapidly growing. Air bubbles rise from the bed, dragging water from below upwards. The resulting vertical circulation suppresses blue algae growth. However, these systems demand electricity of about €25,000 per km2 per year. The airlift promises to mix the water more efficiently,...

A recurrent challenge in the hydraulic engineering is to establish the required stone diameter for a stone protection on mild slopes, since the stability of gravel on a mild slope is not yet sufficiently covered by existing design methods. The objective of this study is to investigate the relation between the loads and the stability of stones on...

As human beings are becoming more and more aware of importance of the environment, resorts to clean energy have provoked great interest for the past decades. As a sort of clean power, wind has been widely considered as an ideal energy source to generate electricity. That is why the offshore wind farm plans have been drawn up, specifically in...

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...

The cross-shore sediment transport is of great importance in the coastal water since it may lead to significant change of coastal profile. Many researches have proved that the sediment transport is proportional to velocity moments. In this study, the velocity moments under wave action in the perpendicular direction to the coastline are studied...

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....

FLNG cooling water outfalls can be characterized as high momentum buoyant jets, relatively close to the surface. The buoyant jet trajectories, spreading rates and surface distribution very much depend on the jet outflow characteristics. A study with the CFD software OpenFOAM has been carried out into the mixing and transport processes of buoyant...

Permeable wooden pile groins have a long tradition as being part of the coastal protection in the Netherlands, as well as in Germany and the United Kingdom. They are built to protect beaches from eroding by reducing the current velocity along the beach and thus its ability to transport beach material. This type of groin is most popular among the...

Wave climates in ports can determine the efficiency of port operations to a large extent, so good predictions of them are important. This thesis therefore focusses on the modelling of wave penetration in ports, using several numerical models as well as a physical model. The goal is to compare numerical wave models for the use of wave penetration...

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...

Moored vessels are subject to wave forces and moments at different frequencies, which induce motions of the body and can be transferred to the mooring lines and fenders. Under extreme forcing and vessel motions, dangerous line breaking accidents can occur or the ship movements can be simply too large to continue the on/off-loading process,...
