Zusammenfassung: | Paucity of suitable records of streamflow for the numerous drainage basins in West Africa makes recourse to the water balance approach to hydrological regionalization necessary. Principal components analysis reduced to three components a water balance data set of 12 variables computed for 109 stations in West Africa. Scores on these components were grouped by cluster analysis into seven hydrological regions. The locations of the 21 international drainage basins in the area vis-a-vis these regions are examined, and most are seen to lie in hydrologically unfavourable environments. The implications of this for future large scale water projects are pointed out. |
