Application of a Videometric Measurement System to Investigate Spatial Dike Breach

Chapter
Part of the Geoplanet: Earth and Planetary Sciences book series (GEPS, volume 1)

Abstract

Breach of a dike can lead to extensive flooding of nearby areas along with both monetary and human losses. Especially, dike breaches due to overtopping have occurred more frequently during the last years, as most dikes suffer from the lack of maintenance and revision. An accurate prediction of the dike failure process is therefore essential for developing effective emergency action plans or establishing adequate safety measures. Of particular interest is information on the breach profiles during a breach to estimate the outflowing discharge. Spatial dike breach tests due to overtopping were conducted at a laboratory channel of the Laboratory of Hydraulics, Hydrology and Glaciology (VAW), ETH Zurich. To record the temporal dike breach profiles, a three-dimensional (3D)-videometric recording system was applied, developed by AICON 3D Systems Ltd. This system allows for a continuous, non-intrusive recording of the sediment surface through the water surface during the dike breach process. The system is presented herein and first results regarding the experimental setup are discussed.
