Report on additional tests – Part C: Influence of low wave steepness

Within the framework of the CLASH-white spot tests, wave overtopping tests on a smooth sloping structure have been performed at UGent. 3 different geometries have been tested during these tests 1) simple smooth dike 2) simple smooth dike with a small vertical part (same crest level as geometry 1) 3) simple smooth dike with a small vertical part...

Effect of obliqueness, short-crested waves and directional spreading, report on additional tests

Based on a database of laboratory data on wave overtopping (around 10,000 tests) a neural network technique is used for producing a generic prediction method. In the first database (around 7,000 tests) the following white spots were detected where additional tests could improve the generic prediction method. This report deals with the laboratory...

Reshaping breakwater tests, additional tests

Tests have been performed with low steepness and reshaping breakwaters at Ghent University and Aalborg University respectively. The reshaping breakwater is a type of breakwater where the information on overtopping is very limited. The additional tests are described in the following four reports: .. D24 – Part A: Effect of obliqueness, short...

Standard tests for roughness factor: Report on additional tests

This report details the results of the second phase of the additional white spot tests undertaken by the University of Edinburgh. Part A was undertaken by Aalborg University who investigated the effect of wave obliquity. Edinburgh were commissioned to undertake a series experiments to determine the relative difference in overtopping...

Free surface numerical modelling of wave interaction with coastal structures

The main objective of Workpackage 5 is to use numerical simulation of wave overtopping in order to solve the problem of suspected scale effects. A second, related, objective is to improve existing codes in such a way as they are able to simulate wave overtopping in a reliable way. The final, single, objective is to numerically model long waves...

Experimentele studie en numerieke modellering van golfinteractie met stortsteengolfbrekers

Description of a VOF model for wave structure interaction (VOF-break). Example calculations for the Zeebrugge breakwater, including prototype measurements of wave penetration into the core of the breakwater. Description of breaking processes on the breakwater.

Technical report erosion resistance of grassland as dike covering

Old dikes are usually still constructed entirely from clay and since 1953 many much heavier dikes have been made from a core of sand with a covering. This construction puts heavier requirements on the covering, as it also does for grassland on a clay layer. These and other developments have led to the need for more insight into the strength of...

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...

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...
