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...

The world is currently in a global energy transition. To reach the global energy goals requires massive deployment of clean and efficient energy technologies. The use of solar photovoltaic (PV) therefore has to be scaled up. Offshore deployment of floating PV would be a suitable solution. There are currently different concepts in development for...

Modelling of power transformers to predict and examine its performance in the presence of Geomagnetic Induced Currents (GICs) is of particular interest in research since these currents that are quasi-DC in nature drive the transformer into half-cycle saturation. During the half-cycle saturation, the increased leakage flux and harmonics have...

In the Waal bed degradation occurs, which is mainly induced by a large number of river regulations measures done in the past. Rijkswaterstaat develops possible measures and new techniques to stop riverbed erosion and/or mitigate the negative effects. One of the possible new techniques to reduce riverbed erosion locally is groyne field...

In the present study the stability of crown wall elements on top of a rubble mound breakwaters is investigated. The first step was conducting a literature review, in order to identify knowledge gaps. It was found that current design methods do not take the freeboard of the crown wall into account when calculating the vertical force acting on it....

The air-conditioning of commercial buildings accounts for approximately 50% of the total energy consumed in India’s commercial sector. Reducing this load is a key step towards minimizing India's greenhouse gas emissions. One culprit is the routine use of fully glazed façades which are chosen for aesthetics but are neither energy efficient nor...

Combined wave-current flow is defined as flow in which waves and currents are present together. One of its occurrences in nature is at a tidal inlet system, where incoming waves meet either a current in the same (following) or opposite (opposing) direction. This type of flow is different when compared to wave- or current-only flows. As a result,...

Gas extraction has caused increased seismic activity in the area of Groningen, bringing about considerable damage to houses. The houses are generally old masonry houses with flexible timber diaphragms. It is of importance to assess the response of these houses in order to apply proper retrofit measures. There has been substantial research on...

Offshore wind farms are rapidly developing in Western Europe as an alternative means of clean energy. The foundation of wind-turbines in the shallow water of the Northern Sea is almost exclusively (over 87%) performed by short rigid monopiles, as an efficient and relatively cheap solution. Scour formation, meaning the soil removal around the...

A specific type of wave is identified as an infragravity wave (IG wave). These waves with very long wave periods, even up to minutes, are possibly dangerous for flood events, increased storm surge and/or failure of coastal defences. Current guidelines for dike safety are often determined for gravity wave dominated systems, so identifying IG...

Nowadays more attention to environmental-friendly sources of energy has been given, aiming to slow down and counteract the damage to the ecosystem product of the abuse of fossil fuels. Different technologies on energy production, solar, wind, tidal, geothermic, etc., have been researched with the additional challenge of how to store it.<br/>From...

The Bristol Channel has one of the largest tidal ranges in the world, with a mean tide of nearly 10.5 m at Avonmouth, and speculations on how to harness this energy date back well over a century. One method is tidal range by the use of tidal lagoons, which operates on principles akin to hydropower. The lagoon is essentially an enclosed reservoir...

Wave runup is generated by energy which remains after wave breaking and travels farther to the coast in the form of a bore. It can be seen as a thin wedge of water running up the beach face (Brocchini and Baldock, 2008). Under storm conditions runup is responsible for beach and dune erosion and accurate runup predictions are therefore required ...

Two-phase thermal control systems are used for payloads that require temperature stability under high and fluctuating heat output. However, the complex interaction between the two phases in a flow makes it hard to predict the performance of such a system. The goal was to develop a numerical model able to predict the transient behaviour of such a...

Geothermal energy is a way of reducing the cost of energy. Deep geothermal energy systems extract heat from very deep soil layers where the temperatures are very high. Shallow geothermal energy systems are about 150 metres deep and they are used to store heat in the soil, to extract it later and use it for space heating. These shallow geothermal...

The Rhine ROFI ( region of freshwater influence) is a dynamic area where various processes and timescales come together. Research has shown that stratification caused by the freshwater outflow of the Rhine alters the tidal currents in front of the Dutch coast. In the case of the Netherlands the tide behaves like a kelvin wave, which causes...

This document describes a study into the influence of alongshore bathymetric variability on currents which form a risk to bathers. Changes to coastal zone management along the Delfland Coast have given rise to questions on the influence of alongshore bathymetric variability on bather risk. Extensive measurement data is available from two...

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...

An increasing number of activities are moved into Arctic regions. As oil and gas companies are exploring the options in these regions, structures are required which can withstand the severe environmental conditions. Existing structures are subjected to heavy mechanical loads due to moving ice sheets. For concrete structures in particular ice...
