Abstract
Recent advancements of space geodetic observations and remote sensing techniques allow to extract hydrological information reasonably well at the river basin scale. Combining this information with in-situ data provide a new opportunity to explore the feasibility of assessing hydrological models at the basin scale. Appreciating such possibilities, a group of researchers from the different institutions in India, has developed a project that envisioned to quantify each component of hydrological cycle at the basin scale and also planned to investigate crustal deformations due to the hydrological changes. The project was financially supported by National Geospatial Programme, Department of Science and Technology, India. A precise assessment of Terrestrial Water Storage (TWS), groundwater storage, soil moisture, evapotranspiration, severity of drought and hot –spells at basin scale and downscaling of the GRACE derived TWS to the sub-basin scale are carried out under this project. Several GPS stations co-located with soil moisture probes are installed in the Ganga river basin to validate and improve the hydrological models. It is planned to present the results over three major river basins of India studied under this project.
