Executive Summary : | The traditional ground based methods of hydrological parameters estimation are mostly point based, and very good temporal resolution, but lack spatial coverage. The large spatial variation in hydrological parameters such as rainfall, SM, ET, Snow Water Equivalent (SWE) and (?TWS) can be easily overcome by remote sensing based hydrological parameters retrieval methods. The temporal variation of some of these parameters can be at sub-daily to hourly time scale, and some of the remote sensing satellites working in constellation mode can easily address such issues. The present project can be used develop and validate the remote sensing based hydrological parameters retrieval techniques with ground truth from existing and future planned set of ground instruments/observations for Indian conditions. The derived hydrological parameters can be used in data assimilation mode for improving the prediction and assessment capability of hydrological models. |
