Parameterisation and calibration of a grid based distributed hydrological model
Parameterisation of hydrological models using remote sensing is currently being studied in a European Union funded ARSGISIP project. Input to hydrological models consists of meteorological data, discharge data and spatial data (slope, soils, land-use and vegetation cover) for model parameterization....
