Abstract: In this study a physically based hydrological model coupled with the SCS curve number method is presented to assess the runoff changes due to land-use changes. In order to approach a reasonable result in hydrologic modelling, satellite-based remote technologies are used to extract land surface parameters. For known rainfall event, future changes in land use can also be incorporated in the model once digital database is available and the change in runoff hydrographs can be estimated. The study clearly demonstrates that the integration of spatial data and the application of a physically based model in a remote sensing environment provide a powerful tool for the assessment of an effect due to land-use change.
