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.

Videometric water surface tracking: towards investigating spatial impulse waves
Author : FREDERIC M. EVERS(1) & WILLI H. HAGER(2)
mass wasting events propagate spatially from a locally confined impact
zone across the affected water body. Due to the highly dynamic and complex processes related to landslide generated
impulse waves, investigations often rely on physical scale models. Conventional wave measurement techniques including
point gauges only allow for a limited number of measurement positions in a spatial environment. For tracking spatial
elevation profiles of the free water surface within a 3D wave basin a more elaborate approach is required. In this paper, a
videometric and therefore non-intrusive technique is introduced for tracking arbitrary water surfaces. With its high density
of measurement points, it facilitates the acquisition of a virtually continuous spatial elevation profile of the free water
surface. In combination with a hydraulic scale model this measurement technique allows for a detailed study of processes
related to the propagation of landslide generated impulse waves. In addition, the techniques presented apply also to other
experimental setups in which a precise acquisition of the water surface is of relevance.Form Required :Published Date : 123
