Spatio-Temporal Calibration and Validation of Streamflow in Watershed of New York.

Hydrologic models that are physically based are used widely for water resource planning and management. Calibration and validation of model at different scale is important in order to address water quantity and quality issues and their management. It is also essential that streamflow calibration and simulation is carried out in such a way that spatial variations in hydrologic parameters within the watershed sub-basins are addressed. The main objective of this paper is to calibrate and simulate streamflow at upstream and downstream locations of the at a forest dominated watershed outlet of Grout Brook, NY. The streamflow calibration and simulation is carried out at two different time periods using a semi-distributed hydrologic Soil and Water Assessment Tool (SWAT) model. This study will address possible uncertainties and error that may affect calibration and validation due to scale differences.
