Land use change is the main factor influencing watershed hydrology and could serve for developing better watershed management practices. The behaviour of each process in hydrology is influenced by its attributes and other processes. Present study analyses the impact of land use change on watershed hydrology in Nallamala forest watershed,India.The Soil and Water Assessment Tool (SWAT) is used to simulate runoff using different land use land cover (LULC) maps of 2000 and 2010. In present study land use changes and hydrological responses were quantified to investigate the runoff responses on annual basis time scale using SWAT to study the impacts of land use land cover change. A calibrated SWAT model simulated annual runoff processes for a period of 10 years i.e. 2000 to 2010. Sensitivity analysis for input parameters is analysed using the SUFI-2 algorithm in SWAT_CUP (Calibration Uncertainty Programme). Four SWAT input parameters are more sensitive including CN2.mgt, Delay.gw, sol_awc.sol and sol_k.sol. Hydrological model could simulate runoff for each sub-basin using two land use scenarios 2000 and 2010,soil map and DEM.It is observed that model results using optimised parameters, hydrological processes are better predicted with statistical evaluation methods like Nash-Sutcliffe Efficiency(NSE) and Coefficient of determination(R2). The results from present study help to quantify the potential impacts of land use land cover (LULC) change on total yield of water within watershed using SWAT model.Downloads
