Vetiver grass is a sustainable and innovative solution for the protection of banks. It is shown that Vetiver grass is able to establish a full-stop of bank erosion caused by rapid drawdown. Therefore it provides us with strong indications that it is highly suitable as an anti-erosion measure. A combination of cohesive soil and Vetiver grass...

Dike design is a very traditional craft. Since many generations dikes have been constructed in our part of Europe. After each disaster the dike was rebuilt, and improved. The improvement was always based on the experiences of the previous flood. For example, for many years the design height of a dike was determined as the height of the highest...

In order to develop a new philosophy of flood safety in terms of probability of a certain level, two mathematical models of breach growth in sandy dikes have become available to determine the flood discharge in case of dike failure. BREACHES 1.0, developed at Alkyon/Delft Hydraulics (Steetzel) and BRES 1.0 at Delft University of Technology ...

The 1400 km Dutch coastline is affected by sea level rise. At this moment a legal framework is made to guarantee the safety of dikes also in future. Also a national policy id developed for compensation of all coastal erosion. Both measures should make it possible for the Netherlands to survive an increased sea-level rise,

The set-up and results of a field experiment on sand-dike breach erosion are described, It is found that the breaching process for the 2.2 m high sand-dike is similar to that in Visser's (1988) laboratory experiments with a 0.6 m high sand-dike. Confrontation of Visser's (1988) breach erosion model with the field data shows reasonable agreement...
