Abstract: Substantial change of the hydrological regime may generally result from excessive withdrawal of water, especially for agricultural consumption, as well as from reservoir regulation, abating flood peaks and therefore decreasing sediment transport capacity of the stream. The decrease of transport capacity is often accompanied (and somehow compensated) by a lower input of sediments to the river, due to reservoir interception, erosion-control works, quarrying activities. The paper describes a 1-D morphodynamic model particularly developed to reproduce the river evolution at watershed scale, over a number of centuries. Although basically one-dimensional, the model includes a component reproducing the evolution of both cross-section profile and riparian vegetation. The model is being applied to the Adige River in Italy, a relatively large watercourse flowing from the Alps to the Adriatic Sea.
