Erosion at transitions in landward slopes of dikes due to wave overtopping

Destructive wave overtopping tests have been performed at more than 20 dike sections in the Netherlands using the Wave Overtopping Simulator to simulate the overtopping waves. The tests show the combined behaviour of turf and substrate up to mean wave overtopping discharges of 75 ?/s per m, meaning wave volumes up to 5,500 ?/m with flow...

SBW Wave overtopping and grass cover strength: Preditions of Prototype Tests

Overview of overtopping with focus on river dikes. Realtin with sod density.

Flow depths and velocities at crest and landward slope of a dike, in theory and with the wave overtopping simulator

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...

Technical report erosion resistance of grassland as dike covering

Old dikes are usually still constructed entirely from clay and since 1953 many much heavier dikes have been made from a core of sand with a covering. This construction puts heavier requirements on the covering, as it also does for grassland on a clay layer. These and other developments have led to the need for more insight into the strength of...
