The Simulator was applied to test the resistance against wave overtopping of grass covered dike slopes in Viet Nam. Observation and measurement during destructive tests were performed to investigate the development process of damage induced by overtopping flow. Damages were likely to be initiated at transition of either geometry or materials, at...

The resistance of various grassed slopes against wave overtopping has been appraised by means of the Wave Overtopping Simulator in situ for a couple of years in Viet Nam. Destructive test results show that a dike slope covered with grass could suffer a certain overtopping discharge not smaller than 20 l/s per m. During testing it was difficult...

Wave overtopping discharges at coastal structures are well described in the EurOtop Manual (2007), including the distribution of overtopping wave volumes. Each volume that overtops a dike or levee will have a certain flow velocity and depth record in time, often given by the maximum velocity and flow depth. This paper describes some further...

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...

Revetments protect the shorelines of coasts, estuaries and rivers against wind wave, ship wave, current and ice attack. The resistance of revetments essentially depends on the properties of the cover layer. The resistance of interlocked pattern placed revetments depends on the weight of the individual stones and the interlocking. Extensive large...

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...

Recently, formulae have been derived for maximum flow depths and velocities on the crest and inner slope of dikes or levees at wave overtopping. Two independent physical model test programs in different wave flumes showed, however, a large difference in the results. The present paper clarifies this discrepancy and shows that the empirical...

In het kader van WV21 wordt door Deltares en een werkgroep gekeken naar doorbraakvrije dijken. Er wordt gekeken naar de definitie van doorbraakvrij en daarnaast naar hoe doorbraakvrije dijken er zouden moeten uitzien ten opzichte van de huidige dijken. In dit kader is aan Van der Meer Consulting gevraagd specifiek uitwerking te geven aan...

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...

Het grondgedachte voor het predictiespoor is geschreven volgens het KOLB-principe (www.thesis.nl/kolb). Dit houdt in dat eerst de mogelijke faalmechanismen worden beschreven op basis van bestaande kennis (wat neem je waar? - feeling). Dus een beschrijving van de huidige stand van zaken. Voor zover mogelijk worden dan de faalmechanismen zo goed...

In the present report field erosion tests of the inner slope of a sea dyke in the province of Groningen (near Delfzijl) are described for the situation of severe wave overtopping. Three types of tests have been performed: tests at the present grass cover, tests at a reinforced grass cover and tests at a section of bare clay. At the reinforced...

Voor het toetsen van een dijkbekleding bestaande uit Noorse steen is nog geen bevredigende toetsmethode voorhanden, vooral omdat de bestaande methode erg conservatief is. De toetsmethode gaat namelijk uit van los gestorte breuksteen, wat een Noorse zetting beslist niet is. Uitgangspunt in dit rapport is een benadering vanuit de "breuksteenkennis...

Noorse steenbekledingen bestaan al heel lang, vanaf begin 1800. De ervaring met de huidige Noorse steen is erg goed. In de laatste 50 jaar is er nauwelijks tot geen schade ontstaan. Aanvullend op een voorgestelde aangescherpte toetsmethodiek voor Noorse steen, is het zinnig na te gaan wat bewezen sterkte voor Noorse steen zou kunnen betekenen....

The European Union funded project DELOS was focused on wave transmission and an extensive database on low-crested rubble mound structures was generated. During DELOS, new empirical wave transmission formulae were derived. These formulae still showed a considerable scatter due to a limited number of parameters included. Neural networks based on a...

In the present report, a Smart Grass Reinforcement for overtopping resistant sea defences is elaborated on a theoretical basis, within the framework of ComCoast, Work Package 3 (WP3). The smart grass revetment concept aims at strengthening the present grass revetments at the crests and inners slopes of sea embankments. Smart denotes a...

The present proposal deals with a presentation of three potentially feasible concepts for strengthening of the sea defences as to allow for increased wave overtopping, within the framework of ComCoast. In addition, for each concept an indicative proposal is given for a further theoretical study (Phase 2) and an indicative approach is shown for...

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...
