Cross-shore profile development during storm conditions: Analysis of field data gathered at Petten sea defence

The majority of population in the Netherlands live well below the mean sea level. At some locations people and infrastructures are only protected from the sea by a narrow stretch of sandy beaches and dunes, so reinforcement works will be necessary to prevent a break through during storm surges. Therefore it is necessary to study problems...

Bresgroei: Een experimenteel onderzoek naar de ontwikkeling van de ontgrondingskuil

In Nederland wordt, ter vervanging van de huidige ontwerpmethodiek op basis van een overschrijdingskans, gewerkt aan een nieuwe, probabilistische ontwerpnorm voor de zee- en rivierdijken. Deze nieuwe norm wordt gebaseerd op een risicobenadering. Hierbij bestaat het risiko uit de kans op een overstroming, gecombineerd met de schade die daardoor...

Physical and numerical modelling of the erosion of a fluid mud layer due to entrainment

The subject of this master thesis is to present the processes taking place at the erosion of a fluid mud layer due to entrainment, to carry out experiments in an annular flume and compare the results of these experiments with a numerical model, which has been elaborated at the TU Delft. The report can be devided into five parts: physical and...

Relatie tussen ontgrondingen en steenstabiliteit van de toplaag

Experimental research on erosion behind stone bed protections. A relation is looked for between the stability parameter of the bed material and the erosion parameter alpha. Roughness and turbulence have been investigated.

Some aspects of near shore processes near Visakhapatnam Harbour

Visakhapatnam is one of the major ports along the east coast of India. An outer harbar in 1976 is constructed to accomadate large ships and to meet the requirements of the ever growing industries of Visakhapatnam. For the maintainance of the Visakhapatnam outer harbour(VOH) two breakwaters are constructed at the south and east end of the harbar....

Report of the practical training done in the general directorate of ports in Portugal, during the months september and october 1986

This is not the main report, but the partial report. Portugal has a coast of approximately 800 km containing a lot of interesting coastal phenomena, such as estuaries, land spits, rock coasts, lagoons, cliffs and rias (areas af sandbanks and canals in open connection with the sea). Also a lot a different harbours can be found along this coast....
