Applications of Soil and Water Assessment Tool for Runoff Modeling of Karam River Basin in Madhya Pradesh

The SWAT 2010 model was applied to the Karam river basin tributary of Narmada for runoff modeling. The capability of the model was tested for a period 38 year (1976- 2012). Karam river which meets the Narmada river basin at Dhar district in Madhya Pradesh. Two rain gauge stations are influencing the project catchment area namely, Nalacha and Mhow. Yearly rain fall and runoff data for 38 year were collected for the study. Using Arc GIS sub watershed boundaries, drainage network, slope, land use map and soil map, are generated. SWAT was linked with calibration uncertainty program (SWAT-CUP) used for the calibration process The model stimulated annual rainfall for 10 year and model was compared with actual observed result. SWAT cup was used for the calibration of the period 2000-2010. The result of this study shows SWAT model can generate the annual average rainfall and produce the runoff very close to the observed value.
