CHARACTERIZING DROUGHT AT MALANVILLE USING A MULTISCALE STANDARDIZED WATER-BALANCE INDEX (NIGER BASIN, BENIN)
The rainfall regime at Malanville (northern Benin, Niger River basin) shows strong intra- and inter-annual variability typical of the Sudano-Sahelian domain, yet drought diagnostics based on rainfall alone do not account for evaporative demand. This study builds and consolidates a standardized water-balance index (SWBI...
