'An Alternative Approach to Flood Forecasting in South Asia' We present several tools developed to improve flood forecasting and warning in the Ganges-Brahmaputra-Meghna Basin in South Asia. These tools use in-situ and remotely sensed information to improve flood forecasting and bypass current limitations presented by lack of data availability, and information sharing in the region. We show preliminary results from a new flood forecasting system along with improvements currently in development. Flooding is endemic to this region given its topography, seasonal monsoon rainfall, land-use, and current lack of good water management and trans-boundary cooperation. It is hoped that both these tools and system in development will improve flood response and offer longer flood warning lead times.
