Preliminary reliability analysis of flood defences in the pilot site ‚German Bight Coast’

This report describes the flood defence structures of the pilot site ‘German Bight Coast’ and the overall probability of failure of all flood defences in the area. First, the flood prone area is briefly described as follows: ? the flood prone area ? the failures observed in the past ? an overview of all defence structures ? the flood defence...

Breaching Processes: A state of the art review

This report provides an overview of the state of the art with regards to embankment breach initiation and formation processes. Basic breach formation processes are explained, including a review of commonly held misconceptions. The different stages of breach initiation and formation are also explained, along with the varying needs of different...

Description of flood defence structures for pilot sites

This report describes individual flood defence structures of all pilot sites in FLOODsite. For each of the 10 pilot sites the following details are described: Ø the flood prone area Ø the failures observed in the past Ø an overview of all defence structures Ø the flood defence structures in detail together with their potential failure modesThe...

EurOtop, European Overtopping Manual - Wave overtopping of sea defences and related structures: Assessment manual

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...

Hydraulic loading of flood defence structures

This report reviews previous investigations on hydraulic loading conditions for different types of flood defence structures such as sea dikes, dunes, beaches and seawalls. For each of these structures the physical processes involved are discussed in some detail and methods are given to either predict relevant input parameters for failure modes...

Hydraulic model tests of an innovative dike crest design

Report on laboratory tests on a crest drainage dike; investigation if a channel in the crest of the dike is able to decrease the amount of overtopping over the dike. Chapter 2 provides details about findings from previous studies and the relevance of those findings to this research project. Available literature on wave run-up and wave...

New results on scale effects for wave overtopping at coastal structures, the CLASH programme

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...

Quantification of measurement errors, model and scale effects related to overtopping

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...

Laboratory measurements on the Zeebrugge breakwater

Within WP4 laboratory investigations for the Zeebrugge rubble mound breakwater have started in the wave flume of Leichtweiß-Institute for Hydraulic Engineering of the Technical University of Braunschweig (hereafter LWI) and in the wave flume of the Universidad Politécnica de Valencia (hereafter UPVLC). In order to check any influence that is...
