SPACE TECHNOLOGY AND PREDICTION OF THE AVAILABILITY OF FLOOD WATER IN THE NIGER RIVER
In the framework of the "JOLIBA Project", the Joint Research Centre (J.R.C.) of the European Communities investigates the potentialities of space technics for crop production forecasting (millet, sorghum and rice) in West Africa. Under the prevailing conditions, space technics can provide input in two domains: telecommunication technics, and remote sensing technics. The present research activity aims to integrate the two techniques to a river flood prediction methodology: A test site has been chosen in the Milo catchment. Field studies made it possible to identify some landscape units suitable as indicators of the hydrological dynamics of river and catchment basin. A clustering of the 199 basins present has been performed according to drainage and retention potentialities. Seven categories of basin were individualized for the monitoring of surface features. The transmission segment of the system will use the DCP function of the Meteosat satellite and allows the connection to national and regional nets in West Africa. Monitoring of land surface characters, on satellite imagery, and collection in almost real time of hydrometeorological data, would allow prediction of flood characteristics on the upper Niger catchment. The "theoretic" flood will then be used as input for propagation model to predict flood water availability downstream.
