Run-off, SWAT Model, Land use, Bangnara basin


The objective of this work was to study the land use changes on runoff. SWAT (Soil and Water Assessment Tool) model and GIS (Geographic Information System) were applied to estimate amount of the runoff from the land use changes in Bangnara Basin. The reliability of the model was calibrated with the observed data from X.73 station by adjusting the coefficient of 8parameters that were sensitive to runoff in SWAT Model. The goodness of the calibration results were assessed based on the determination coefficient (R2), found in the ranges of 0.750 to 0.848 and Nash-Sutcliffe efficiency (NSE) found in the ranges of 0.438 to 0.598, which were statistically acceptable. The results showed that the Bangnara Basin is 603.57 km2, 263 hydrological response units. The assessment of runoff was done during January 1, 2017 to December 31, 2017 from land use data in 2009 and 2016 indicated the total annual runoff volume 1,170.17 MCM and 1,194.65 MCM, respectively. According to the runoff from the land use in 2016, the forest area has decreased by 15% and urban areas and agricultural areas has increased by 7.17%. This led to the decrease of watershed area 16.43 MCM. Moreover, the results indicated that the peak flow significantly increased during the rainy season.
