Transition structures in grass covered slopes of primary flood defences tested with the wave impact generator

The stability of grass covered slopes on primary flood defences under wave attack is an important aspect with respect to the strength of the entire dike. In a grass slope many transitions to objects (poles, stairs, fences, buildings et cetera) or other revetments (concrete, asphalt, placed block revetment) can be present. This can potentially...

Hydraulic performance, wave loading and response of Elastocoast revetments and their foundation - a large scale model study -

ELASTOCOAST revetments are highly porous structures made of crushed stones which are durably and elastically bonded by Polyurethane (PU). To improve the understanding of the physical processes involved in the wave-structure-foundation interaction and to develop prediction formulae for both hydraulic performance and wave loading more than 75...

Laboratory Tests on the Erosion of Clay Revetment of Sea Dike With and Without a Grass Cover Induced by Breaking Wave Impact

This report addresses the preparation and performance of laboratory tests on a the erodibility of clay cover with and without grass, subjected to impact pressures generated by controlled falling water mass Three types of clay, representing different erosion resistances as well as grass cover of moderate quality have been used in order to gain...

Wave impacts on vertical seawalls and caisson breakwaters

In most developed coastal areas, seawalls protect towns, road, rail and rural infrastructure against wave overtopping. Similar structures protect port installations worldwide, and may be used for cliff protection. When a large tidal excursion and severe environmental conditions concur to expose seawalls and vertical face breakwaters to wave...

Shock pressure interactions on prototype sea dykes caused by breaking waves

This paper deals with shock pressure phenomena due to breaking waves acting on sloping faces of sea dykes and other dike revetments. The full-scale investigations were carried out in the new research facility LARGE WAVE CHANNEL in Hannover. Germany. Maximum shock pressure estimations are given for practical slopes 1:4 and 1:6. An extension of...
