Breaching of small-scale sand embankments by overtopping
Author : SYLVIE VAN EMELEN(1), SANDRA SOARES-FRAZAO(2) & YVES ZECH(2)
ABSTRACT
This paper presents different small-scale breaching experiments by overtopping conducted on different sand
embankments. Two main types of experiments are considered: one-dimensional experiments where overtopping occurs
over the full width of the dike, and two-dimensional experiments where the process starts from an initial breach in the
embankment. Coarse and fine sand were used in both cases, and for the one-dimensional cases, the presence of a
stabilizing downstream sand layer is investigated. The breaching process for all the considered experiments is analyzed by
comparisons with existing theoretical descriptions for the evolution of the longitudinal breach profile in dikes made of either
cohesive or non-cohesive material.
