  Flood forecasts are crucial for effective individual and governmental
protective action. The vast majority of flood-related casualties occur in
developing countries, where providing spatially accurate forecasts is a
challenge due to scarcity of data and lack of funding. This paper describes an
operational system providing flood extent forecast maps covering several
flood-prone regions in India, with the goal of being sufficiently scalable and
cost-efficient to facilitate the establishment of effective flood forecasting
systems globally.
