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...

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...

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...

Van Mierlo, F.A.J.M. (author)
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...

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,...

In this study regular and irregular waves are simulated with a numerical model. The aim of this study is to perform a numerical investigation into the reflection and transmission of the different waves forcing in a porous breakwaters. There are different types of numerical models available for solving the behaviour of waves in coastal regions...

The determination of wave conditions in partly sheltered areas is a challenging task for coastal engineers. Knowledge about these conditions is important for the design of coastal structures, the planning and operation of ports. Numerical models play an important role in the assessment of these conditions. Various types of models have been...

The main goal of this project is to verify the numerical model SWASH when dealing with overtopping prediction by comparison of full scale measurement results to results of numerical model testing. For that purpose, the harbour in Zeebrugge (Belgium) has been considered; there, several storm events have been measured in a rubble mound breakwater...

This study presents an intercomparison of a SWAN and SWASH wave model and 3D laboratory experiments for an existing navigation channel towards a harbor. Results show that the spectral refraction model SWAN underestimates the wave conditions in the channel and at the lee side of the channel especially - for longer waves travelling under a small...

In this paper, a numerical wave-flow model SWASH, based on non-linear shallow water equation with non- hydrostatic pressure, is applied to the estimation of wave overtopping over a dike in shallow foreshores. First sensitivity analysis is conducted to see the influence of wave generation, grid size, time window and bottom friction by one...

This paper presents the application of the open source non-hydrostatic wave-flow model SWASH to propagation of irregular waves in a barred surf zone, and the model results are discussed by comparing against an extensive laboratory data set. This study focus not only on wave transformation in the surf zone, but also on the numerical prediction of...

Wave penetration inside harbours has been one the main issues that port planners and engineers have had to deal with in recent years. Wave conditions inside harbours trigger vessel movements, create dynamic loads on port structures and condition harbour exploitation and safety. For this reason in the recent past maritime and port engineers have...

Groynes are commonly used in the major rivers in the Netherlands. They confine the flow of the river to a main channel but also act as resistance element once submerged and in that way influence the stage discharge relationship of the river. Several formulas exist describing groynes as a drag resistance. Another possible way of determining their...

Characteristics of the individual wave height distribution in shallow water have been investigated using measured wave data and results of numerical simulations using the non-hydrostatic SWASH model. It is shown that the SWASH model is capable of reproducing the temporal and spatial variation of surface elevation in a wave flume and the...

The design formula for rubble mound breakwaters by Van der Meer has an unclear Notional Permeability term. This term causes a lot of confusion for designers. In the past many people have tried to derive a better formulation for that term by experimental and analytical research. The goal of this study was to obtain a better formulation along a...
