1-D Morphodynamic simulation of Trebbia riverbed after San Salvatore dam removal

Dams are recently being demolished for river restoration purposes in order to increase quality and health of the rivers. One of the cases to put into consideration would be San Salvatore dam located in Emilia-Romagna region ( Italy) which nowadays is a dam not used for its main purpose but for touristic attraction. This study was conducted to perform a one dimensional assessment of the evolution of the riverbed in the case of the removal of San Salvatore dam. The results shown that the river would recover its natural slope within a period of four years. In contrast, the volume of sediments transported by the removal would not be significant to put in risk of flood the downstream populations.
