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.

Scale Model of Overtopping of Waves Propagating Laterally to a Structure
Author : Elodie Gagnaire-Renou, Damien Violeau, Jean-Romain Delisle and Michel Benoit
The overtopping over a seawall or dyke by a wave train propagating laterally to those (90 incidence) is poorly documented in the scientific literature. In order to improve our knowledge about this phenomenon, a physical model was built in a wave basin. This work presents the design of the scale model and the analysis of measurements. The phenomenology of lateral overtopping is displayed on dimensional grounds. A theoretical approach, based on simplified assumptions, is proposed and compared to the measurements given by the scale model. Two waterworks were built in order to be tested simultaneously: a vertical wall and a dyke with slope 1:3. Model tests were done under regular and irregular waves. As for the overtopping rates on the vertical wall side, the results are consistent with the simplistic theoretical approach and show a similar magnitude. On the dyke side, the overtopping rates are much smaller for regular waves and an upper bound was found for irregular waves.
