Distributed hydrological modelling within SCARCE project: integrating water, sediments, quality and vegetation.

Water related models are mathematical models used to reproduce several descriptors (called also state variables) of the Water Cycle within a catchment. Indeed, the water balance is the driving force behind everything that happens in the catchment. Hence, to accurately predict the movement of pesticides, sediments or nutrients, the hydrological cycle simulated by models must conform to what is happening in the catchment.
