2002b. Sensitivity of the INCA model to N process parameters and hydrological input
Abstract: The Integrated Nitrogen in CAtchments (INCA) model simulates nitrogen transport and processes within catchments. It was applied to the Simojoki river basin in northern Finland where major human impacts are forest management and atmospheric nitrogen deposition. In this work the main emphasi...
