This study attempts to show how data from low-resolution meteorological satellites, such as those supplied by the AVHRR receiver from the NOAA satellites, can be used to characterise the spatio-temporal dynamics of the surface areas of five west African river basins. Using ten NOAA-HRPT images, the general evolution during the 1987/88 dry season and the beginning of the 1988/89 season is analysed, as well as the specific behaviour patterns of each basin. The creation of a data bank is proposed which assimilates certain descriptive elements of the surface conditions of the principal west African river basins. This collection of data would be complementary to the data contained in the existing hydro-meteorological data banks.
