NUMERICAL SIMULATION OF THE MOTION OF A LOOSE REVETMENT BLOCK

A. Bezuijen, J. Wouters, H. den Adel

Abstract


The movement of a block lying loose in a placed block revetment under wave loading was simulated numerically. The results have been compared with the results of large scale model tests in which the motion of a block and the pressure distribution in the filter layer underneath was measured. It appeared that the mechanism concerning the pore pressure distribution and the block movement are described well in the numerical program. The block movement as calculated in the program is higher than measured. The reason for this is described in this paper.
