Dam removal has garnered significant attention as an alternative option for river restoration over several years. To that end, the Open Rivers Programme has proposed an innovative initiative in Italy to restore the Trebbia River by demolishing the obsolete San Salvatore Dam. This thesis delves into a comprehensive assessment, including both one dimensional and two-dimensional hydrodynamic modeling, alongside 1D morphodynamic numerical simulations, to evaluate the feasibility of removing such a dam and its potential impact on the downstream due to the impounded sediments transport. This thesis includes a thorough set of studies, starting with the acquisition of point clouds aided by unmanned Aerial Vehicles (UAVs) and continuing with post-processing using CLOUDCOMPARE to generate a high-resolution Digital Terrain Model.
