In recent years, hydrological models have been used in assessing complex hydrological processes occurring within a watershed. This study focused on application of physically based distributed hydrological model Soil and Water Assessment Tool (SWAT) interfaced with ARCGIS software over the Kangimi Dam sub-watershed, located in Kangimi river sub-basin of Kaduna basin, in Igabi Local Government Area, about 37km away from Kaduna metropolis, Kaduna State, Nigeria. The study aimed at calibrating and validating the model for streamflow simulation. The model was run for the period from 1979 to 2014 with a calibration period from 1983 to 1986 and a validation period from 1987 to 1990 which was period of discharge data. Calibration and validation of the model were achieved using the soil and water assessment tool-calibration uncertainty programs (SWAT-CUPs) with sequential uncertainty fitting (SUFI-2) algorithm. Based on recommended statistical coefficients, the model evaluation indicated a very good performance for both calibration and validation periods with (R2) and (NSE) to be 92% and 82%, for calibration, and 93% and 86%, for validation period respectively and good agreement between measured and simulated values of monthly scale discharge. The findings of this study can be useful in runoff simulation and to efficiently support water management policies in Kangimi Dam watershed. [ABSTRACT FROM AUTHOR] |
