Remote sensing and GIS data products for hydrological modeling

Accurate modeling will require estimation of the spatial and temporal distribution of the water resources parameters. During the last decades engineers and planners have shown the increasing interest of applying Geographic Information Systems (GIS) and satellite Remote Sensing (RS) technologies to extract land surface parameters, which exist as a threshold in early days to approach reasonable results in hydrologic modeling. With the advancement of the computer technology, GIS and RS have become efficient tools to integrate the spatial and non-spatial databases for the hydrological modeling. In this study a hydrological model was developed for the Bata River basin, which is one of the tributaries of the Yamuna river basin in India. Infiltration losses, Unit hydrograph and river routing are the main model components.
