Modeling of Bharathapuzha River Basin Using SWAT Model and SUFI-2

This paper presents the hydrologic modelling of Thuthapuzha sub-basin of Bharathapuzha river basin for efficient water management practices using the Soil and Water Assessment Tool(SWAT 2012) model. The objectives of the research were to apply Geographic Information System(GIS) and SWAT model for simulation of water discharge with input data including: Digital Elevation Model(DEM), landcover of and soil map. The SWAT 2012 model is interfaced with ArcGIS. The model was also calibrated from 2005 to 2008 and validated from 2009 to 2011 using SWAT CUP SUFI-2 Algorithm. The study shows that SWAT model is a capable tool for simulating hydrologic components of Thuthapuzha sub-basin.
