Submerged breakwater influence on beach hydrodynamics: A 2DV approach

This master's thesis is written using data from experiments performed in the framework of the Human Capital and Mobility program of the European Union. Six universities work together to solve some of the unknown aspects related to the use of submerged breakwaters along sandy coasts. In this study data from 2DV tests carried out in Delft and...

Modelling the impact of an offshore breakwater on the shore

This report is the result of a master thesis of the author, student at Delft University of Technology, faculty of Civil Engineering. The study was carried out at DELFT HYDRAULICS. In this report the effects of an offshore breakwater on the shore are investigated with the morphodynamic models DELFT2D-MOR and DELFT3D. These, respectively 2...

Brandingsruggen voor de Delflandse kust

De Nederlandse kust is verre van uniform. Zo is een opvallend verschijnsel langs de kust het ontbreken van brandingsruggen voor de Delflandse kust, ter hoogte en ten zuiden van Scheveningen. Deze brandingsruggen worden normaliter gevormd onder brekende golven ter plaatse van de brekerlijn. Dit komt mede omdat onder de bijna brekende en net...

Sediment concentrations and Sediment transport in case of Irregular breaking waves

Coastal changes occur mostly as a result of changes in sediment transport along the coast. If at cross-section A, the sediment transport is for any reason larger (or smaller) than at cross-section B, accretion (or erosion) will take place in between the two cross-sections. For prediction of coast-lines in the future, the prediction of the net...

The dynamics of breaker bars: Considered as a diffusion process

In the scope of NOURTEC, an EEC project, efforts are made to simulate the behaviour of executed foreshore supplies with the aid of mathematical computer models. One of the models used are line models. On behalf of the DUT two studies contribute to NOURTEC line modelling. One concentrates on the longshore transport, and the present study focuses...

Profile development of a nourishment behind a submerged breakwater

A literature review is undertaken to understand the causes and the effects of the first process. Using the resulting equations, the UNIBEST-TC program is verified for the process of wave transmission over and through a submerged breakwater. Due to the fact that only impermeable breakwaters can be implemented in the program, deviations occur. For...

Numeriek model voor de berekening van kustlijnveranderinen t.g.v. golven en getij

In samenwerking tussen Rijkswaterstaat afdeling Kustonderzoek van de Directie Waterhuishouding en Waterbeweging en de vakgroep Kustvlaterbouwkunde van de Technische Hogeschool in Delft is een serie rekenprogrammma's tot stand gekomen met het doel de veranderingen van kustvormen onder invloed van golfaanval te voorspellen. In 1975 heeft Casteleyn...
