Reservoir dams: Wave conditions, wave overtopping and slab protection

This report describes research to simplify and consolidate the prediction of wave action in reservoirs; to calculate wave induced discharges on embankments; and to extend work on blockwork and slabbing protection for dam faces presented by Herbert et.al (1995) in the companion report SR 345. The report should be used by engineers involved in the...

Gekoppelde instabiliteit van de Maeslant Kering: Vier lineaire modellen

In de ontwerpfase van de Maeslant Kering zijn door het WL tweedimensionale en driedimensionale modelproeven uitgevoerd. Tijdens de driedimensionale proeven werd een aantal niet voorziene instabiliteiten waargenomen. Naar aanleiding van deze proefresultaten werden het deurprofiel en de vormgeving van de onderzijde veranderd, zodat de stabiliteit...

Shore protection manual: Volume I and II

Design manual for coastal structures. Note that this manual is replaced by the Coastal Engineering Manual. However, this document contains quite some useful information for present day coastal engineers

Laboratory investigation on the overtopping rate of seawalls by irregular waves

Series of measurements with irregular waves were undertaken for model seawalls of vertical walls with and without protection by concrete block mounds. Experimental data were compared and supplemented with theoretical calculations by the combination of the author's random wave breaking model in shallow waters and the weir type overflow model. The...

Stability tests of the Europoort breakwater

This paper deals with model tests conducted at the Delft Hydraulics Laboratory (DHL) and the River and Harbour Laboratory at the Technical University of Norway (RHL) for the design of the Europoort Breakwater. A series of tests with regular waves was conducted at the DHL from which the design of the breakwater was decided. The chosen design was...

The use of model tests for the design of maritime structures with regard to wave action

The hydraulic model is playing an increasing part in the process of hydraulic designing and it seems even to have taken over the dominant position that experience and tradition had held for such a long time. But, however important the model tests have become, they are not the only means available to the designer, nor does he have to rely solely...

Symposium "Research on wave action"

Symposium organised at Delft Hydraulics on the development of research in waves and wave structure interaction.

Application of laboratory tests in harbour design works

It is described why, and to what extent the practicing engineer makes use of model tests in his design of rubble mound breakwaters. Furthermore an example is shown from practice illustrating the application of models for investigation of wave penetration into harbours. Especially the way in which model tests can confirm and supplement...

Wave action on slightly immersed structures, some theoretical and experimental considerations

This memorandum proposes a mathematical approach of the interactions between a non-viscous fluid with a free surface and an assembly of structures composed of shells, whether fixed or not, partially or totally immersed in the fluid. Some fundamental aspects of the problem, such as the effects of the free surface and of the mutual influence of...

Wave shock forces: An analysis on deformations and wave forces in the wave and the foundation

At the inauguration of two advanced wind-wave flumes in the Netherlands, three decades after BAGNOLD's pioneer work, and one decade after the Haringvliet sluice investigation and the joint Dutch-Danish investigation of the Hanstholm breakwaters, it seems appropriate to summarize current knowledge on wave shock phenomena. These may be classified...
