overgangen tussen bekledingen, trappen en overig dijkmeubilair. De validatie is gebaseerd op verschillende praktijkproeven uitgevoerd in Nederland en België, waar de cumulatieve overbelastingsmethode in relatie tot de definities van het schadegetal is toegepast. De engineering tools voor de belastingfactoren zijn deels gebaseerd op theoretische...

Het Hoogheemraadschap Hollands Noorderkwartier (HHNK) onderzoekt de mogelijkheid om de Havendijk bij Den Oever te versterken. Deze dijk is onderdeel van de primaire waterkering in Dijkringgebied Wieringen (Dijkring 12) en bleek bij de landelijke toets op veiligheid een “onvoldoende” te scoren op het toetsspoor “Hoogte”. Een oplossing wordt...

Het Hoogheemraadschap Hollands Noorderkwartier (HHNK) onderzoekt momenteel de mogelijkheid om de Havendijk bij Den Oever te versterken. Deze dijk is onderdeel van de primaire waterkering in Dijkringgebied Wieringen (Dijkring 12) en is onvoldoende hoog. Een van de mogelijkheden om de golfoploop te beperken wordt gezocht in de toepassing van een...

The investigations of FlowDike 1 and FlowDike 2 on the effects of onshore wind and longshore current on wave run-up and wave overtopping for perpendicular and oblique wave attack. These variables were two of the missing effects in freeboard design and therefore a main interest for design purposes. Model tests were carried out in the shallow...

The manual has been intended to assist engineers who are already aware of the general principles and methods of coastal engineering. The manual uses methods and data from research studies around Europe and overseas so readers are expected to be familiar with wave and response parameters and the use of empirical equations for prediction. Users...

An introduction to the principles and fundamentals of designing rubble mound breakwaters, led to the definition of two important white spots in designing rubble mound breakwaters. These were selected for further investigations in the present thesis. 1. Design of berm breakwaters: A generally lack of data and design formulae was identifed, but...

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...

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...

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...

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...

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...
