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.

Breaching of small-scale sand embankments by overtopping
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.
