Abstract
    The solid load level in the Niger River proved to be subject to distinct seasonal variations, the highest concentration being attained well before peak river discharge. A total of 25.4x109 kg of sediment was flushed into the Atlantic through the drainage system in 1980-81, representing an upward review of a previous estimate stated in MARTINS (1982). The specific erosion rate then becomes 20.5·10³kg·km-2·y-1, the highest so far measured in Africa. The composition of the transported sediment reflects the chemical disintegration of silicate rocks predominant in the basin.
