摘要：

Seventy-two water samples were collected in the Niger river at Bamako (Mali) during the years 1990, 1991 and 1992. Analyses allow the determination of the geochemical weathering budget, estimation of the rates of chemical erosion, physical erosion and profile thickening for a tropical basin under rather dry climatic conditions. For comparison, the same weathering parameters were determinated for the basins of the Amazon (Brazil) and the Chari (Chad).
