From past to present: Biodiversity in a changing delta

A large-scale coastal engineering project (the ‘Delta works’) changed large-scale, dynamic estuarine nature in the southwest of the Netherlands into a diverse mosaic of ecosystems with different characteristics. This led to a suite of ecological problems, which is why plans are made to restore estuarine dynamics. Until today the effect of the...

Dynamic behaviour of hydraulic structures

English translation of ""Dynamisch gedrag van waterbouwkundige constructies". The subject is treated from the standpoint of hydrodynamics and applied mechanics, in which a certain knowledge of both fields of study is presupposed. The interaction phenomena are discussed on that basis. The subject matter is not treated exhaustively, but the book...

LABORATORY STUDY OF A DYNAMIC BERM REVETMENT

A series of physical model tests was conducted in a wave flume to study the effect of dynamic rubble protection in front of a vertical bulkhead. This rubbble berm revetment was placed in front of a bulkhead with stone size such that wave action would reshape the berm into an equilibrium profile. Profiles of the berm were taken before and after...

Development of a Two-Scale Turbulence Model and Its Applications

The use of second order closure turbulence model in predicting turbulent flows is known to be more successful than the classical mixing length model. However, it is found that if the turbulence constants are not altered or modified, the second order closure turbulence model is unable to predict satisfactorily f or some flows such as round jet...

Pressures in Sand from Waves and Caisson Motion

In The Netherlands recurring floods have occurred in the southwestern part of the country from infrequent large storm surge from the ocean. The Delta plan was originated to increase the safety against flooding. This resulted in shortening of the coastline by closure of various estuaries, including the Eastern Scheldt estuary. A closure of the...
