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.

2dh modelling of a reservoir flushing compared with lspiv measurements

A reservoir flushing was completed on September 2008 in the Longefan reservoir (Arc en Maurienne River, France). This reservoir (approximately 300m500m) is part of the EDF (French Electricity company) hydropower system. It is mainly used for the sedimentation of the water released from the upstream hydropower plant and for temporary storage for the next plant. LSPIV measurements were completed during the flushing event using three cameras covering the main zones of interest (entrance, main channel and exit). For each movie, biologically degradable chips were injected to produce visible patterns on the surface flow and facilitate the LSPIV processing. Two 2DH hydrodynamic models (Rubar20and Telemac2D) were applied to the system and their results were compared to the experimental data. Advantages and limits of these models were discussed. In particular, the effects of water level and wind were studied as well as the direction of the jet entering the reservoir.
