Impacts of hydraulic releases from a hydroelectric power plant on bedload velocity and bed alteration in the Warche River (Belgium) ; Impacts des lâchers dus à une centrale hydroélectrique sur l'avancée de la charge de fond et sur l'altération du lit sur la Warche (Belgique)

This study is based on the Warche River in the northern Ardennes (Belgium), on a 5 km stretch downstream of the Bütgenbach hydroelectric powerplant built in 1932. The hydroelectric powerplant releases a flow of 10 m³/s almost daily, which corresponds to the morphogenic flow (0.6 bank flow). But then, the dams play an important role in flood control and significantly reduce the number of large floods above the bankfull discharge. A study in the 1990s showed that after the dam’s construction, a general incision of the whole 5 km stretch occured in about 30 years, followed by a doubling of the ch... Mehr ...
