Complement on IAG 2022 poster : "Long-term impacts of hydropower plants on the sedimentology and morphology of the Warche riverbed (Belgium)" ; Complément du poster de l'IAG 2022 : "Les impacts d'un barrage hydroélectrique sur la sédimentologie et la morphologie du lit de la Warche"

Significant hydrological and morphological changes occur with the construction of hydropower plants. The main modifications are related to changes in the hydrological regime and disturbances of the sediment continuity. This study is based on the Warche River in the northern Ardennes (Belgium), on a 7 km stretch downstream of the Bütgenbach dam built in 1932. During the winter months, the hydroelectric power plants release a flow of 10m³/s almost every day, which corresponds to the morphogenic flow (0.6 bankfull discharge). A study carried out in the 1990s (Assani and Petit, 1997) showed that,... Mehr ...
