Hydraulic model tests on breaching with and without waves

This report describes small-scaled experiments performed at Leichtweis-Institute for Hydraulic Engineering and Water Resources, Technical University Braunschweig (LWI). The experiments have been conducted to investigate the development of dike breaches in homogeneous sand dikes with and without a clay layer. The used scaling factor was 1:10.The purpose of the tests is to prepare large-scale model tests in the Large Wave Flume of Hannover (GWK) and to learn about required measurement equipment, how to optimally perform the tests and some qualitative difference between tests performed for overflow conditions and wave-induced overtopping conditions.
