In recent decades, the maintenance of reservoirs with residual flow management in the Saane River has led to a lack of bedload dynamics and a deficit. The consequences included strong vegetation development, extensive restriction of morphological dynamics with habitat losses and clogging of the river bed (colmation). The artificial floods released since 2016 support relocation of sediments, initiation of habitat changes and removal of fine material from the river bed. However, there are still uncertainties regarding the optimal dimensioning of the floods in order to achieve a comprehensive redynamization of the floodplain with an adequate loss in energy production.
