In the design of rubble mound breakwaters, nowadays single layer systems using concrete armour units have become more common practice compared to conventional two layer systems. However, after the introduction of the accropode in eighties, a small number of single layer armour units have been developed over the years; for example core-loc, A...

Within the framework of WTI, Research and Development of Flood Defence Assessment Tools (Wettelijk Toetsinstrumentarium), which is called in Dutch: WTI-2017 "Onderzoek en ontwikkeling landelijk toetsinstrumentarium", research was carried out to develop an erosion model for grass in the wave run-up zone consistent with the current model in use...

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 idea of the Wave Run-up Simulator is based on the experiences with the Wave Overtopping Simulator. It is possible to simulate wave tongues overtopping a dike crest in reality. It must also be possible to simulate waves in the run-up and run-down zone of the seaward slope. This is the zone after waves have broken and when they rush-up the...

The US Wave Overtopping Simulator has to simulate overtopping discharges up to 2 cfs/s/ft for wave conditions of respectively 8 ft with a peak period of 14 s and 3 ft with a period of 6 s. This requires a Simulator which is in size about three times larger than the existing Dutch one. This report describes the theory of waves overtopping the...

The Wave Overtopping Simulator was developed in 2006 and destructive tests have been performed in February and March of 2007, 2008 and 2009 and will probably be continued in 2010. The tests show the behaviour of various inner slopes of dikes, embankments or levees under simulation of wave overtopping, up to a mean overtopping discharge of 125 l...

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...

This report describes small-scaled experiments performed at Leichtweiß-Institute for Hydraulic Engineering and Water Resources, Technical University Braunschweig (LWI). The experiments have been conducted to investigate the development of dike breaches in homogeneous sand dikes with and without a clay layer. The used scaling factor was 1:10.The...

The ‚Guidelines and Recommendations for the Design of Coastal Structures (EAK)‘ published in 1993 (Die Küste, H. 55) have been revised based on today’s scientific knowledge, technical development and practical experience of the past years. Major parts of the recommendations have been re-written. Together with the unmodified recommendations, D, E...

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...

The main objectives of this study was to analyze waves and water levels, from existing climate data, to make conclusions about how the beach, particularly the sand dunes, at Ystad Sandskog has been influenced by the coastal climate up to today. Based on available forecasts, possible scenarios were developed for this area, making it possible to...

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...

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...

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...
