A conceptual flash flood early warning system for developing countries is described. The system uses rainfall intensity data from terrestrial microwave communication links and the geostationary Meteosat Second Generation satellite, i.e., two systems that are already in place and operational. Flash flood early warnings are based on a combination of the Flash Flood Guidance method and a hydrological model.

The desert areas of the country had remained backward in many respects due to difficult physiography varying agro-climatic conditions and distinct socio cultural features. Since the people living in these areas were facing hardships owing to geo-climatic conditions, the desert development programme was introduced as a centrally sponsored scheme in 1977-78.
