Physical model tests on stability and interlocking of new breakwater armour block Crablock

The protection of breakwater structures is in this research considered. The design of rubble mound concrete armour layers for breakwaters can be divided in a single layer system and a double layer system. The single layer system is nowadays mostly applied because of the high interlocking, high stability of the structure, reduction of concrete...

Breach Erosion of Earth Dams

In this report a breach erosion model for earth dams is presented. Descriptions of historical earth dam failures and data of (field) experiments are used to form a model in which the geometric development of the breach is emphasised. Three components form the basis of this model: 1. A water balance in which the inflow into the upstream reservoir...
