Research Projects

The water balance or quantification of hydrological cycle components of an area or watershed/basin can only be done with the help of hydrological models, and is one of the most common and important inputs for any water resources management activity. The hydrological models can be estimated using monthly to annual simple water balance based methods, using lumped semi-empirical models working at watershed scale, semi-distributed physical models with working at hydrological response unit (HRU) scale and fully distributed physical grid based models. In all these hydrological models, remote sensing and GIS plays an essential role by providing information on rainfall, land use land cover (LULC), soil, digital elevation models, and land surface temperature. Most of the hydrological models also need ground based hydro-meteorological data such as precipitation, temperature, water level and discharge for simulation, calibration and validation of hydrological models. The present project envisages development and validation of hydrological models at different climate and topographical regions of India, with integration of ground and space based datasets, so that improvements in overall hydrological prediction and assessment can be done.
