IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Development of a numerical model to predict the erosion of a dike after the failure of the revetment using time dependent boundary conditions

ABSTRACT
This paper describes the development of a numerical model to determine the erosion of a dike. The numerical model is
based on large scale physical model tests and contains the derived formulas for the erosion rate of clay and sand.
Recently, the formula for the erosion rate in clay was adapted according to the results of numerical simulations and
included in the numerical dike erosion model. Furthermore, it was noted that the numerical dike erosion model did not
work appropriate with a varying water level, such as from storm surges or in tidal areas. Therefore, the model is recently
adapted for a varying water level. The new procedure had to be evaluated by engineering judgement based on several
test cases, because there are no experiments with a varying water level to verify the model. One of the test cases is
presented in this paper.
