Impact of hydroelectric power releases on the morphology and sedimentology of the bed of the Warche River (Belgium)

Description :
This study concerns a 7 km long stretch of the river below a dam constructed in 1932 to ensure an optimal supply of water for the production of electricity of another reservoir downstream. Large releases are made very regularly (almost every days in winter). The impacts of these hydrological modifications on the bed morphology and sedimentology below the Butgenbach dam have been studied and geomorphological modifications have been identified : doubling of the width of the channel in 45 years, reduction in the number of riffles and pools, increase in the number of gravel bars and islets and increase in bedrock outcrops in the channel.
