The CLASH project (Crest Level Assessment of Coastal Structures by Full Scale Monitoring, Neural Network Prediction and Hazard Analysis on Permissible Wave Overtopping, www.clash-eu.org) funded by European Union (EU) through contract no. EVK3-CT-2001- 00058, investigated wave overtopping for different structures in prototype and in laboratory ...

CLASH is concentrating on investigations of wave overtopping for different structures in prototype and in laboratory. The model investigations have focussed on wave overtopping and the comparison of overtopping results from small-scale model tests and prototype measurements. Possible differences in the results from small-scale tests and...

One of the main objectives within the EU-project CLASH (www.clash-eu.org) was to create a generic prediction method for wave overtopping at coastal structures by means of the Neural Network technique. An extensive and homogeneous database on wave overtopping was set up within CLASH, mainly with the aim to be used for the training process of the...

Following this general introduction, Chapter 2 provides the structure of the program and the description of the parameters involved in the prediction tool. Then, Chapter 3 provides an explanation of the estimation and schematisation of the hydraulic and structure parameters. Finally, Chapter 4 describes the use of NN_OVERTOPPING 2, including: i....

Within the framework of the European project CLASH phenomena related to wave overtopping are studied. One of the topics that require further attention is the influence of low-frequency waves on wave overtopping. Here, use is made of field measurements performed at the Petten Sea-defence (by Rijkswaterstaat and made available by RIKZ) and...

In september 1989 is een proefvak aangelegd op een zeedijk in het Waterschap het Vrije van Sluis nabij Breskens. Het betrof hier een plaatbekleding van open collo"idaal beton. In 1990 is voorts een proefvak aangelegd op het talud van een winterdijk in het rivierengebied. In dit vak, op de Waalbandijk te Ochten in het Polderdistrict Betuwe, wordt...

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...

It is proven that wave run up on rough slopes is underestimated in small scale model tests due to scale / model effects. Given this fact, the same effects are suspected to be present for wave overtopping. A thorough comparison between prototype measurements of wave overtopping at three different coastal structures and scale model tests of these...

Within the framework of the European project CLASH phenomena related to wave overtopping are studied. In this report a method to predict wave overtopping at a wide range of coastal structure types is given. The method is based on Neural Network modelling of the mean wave overtopping discharge. The method can be applied for coastal structures...

This report provides a methodological background that will be used in the assessment of hazards of overtopping. Those assessment methods that attach a monetary value to the effects on resources are focussed upon. The relationships between the characteristics of overtopping and the use of specific valuation techniques is further explored....

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...

Prediction of wave overtopping discharges for seawalls / breakwaters have improved significantly over the last 25 years, but processes associated with overtopping hazards to people on or close behind seawalls are not yet well understood. Despite research advances in recent years, there remain important gaps in knowledge and disagreements over...

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...
