Hydrological modeling as a tool for water resources management of the data-scarce Brahmaputra basin

A robust hydrological assessment is a challenging task in regions of limited hydro-climatological information. This level of uncertainty is further augmented in studies of flood hydrology for regions like the Brahmaputra River basin, where spatial variations of topography, land use, soil, and weathe...
