Evaluation of Soils Degraded by the Advance of the Salt Wedge and the Decadal Frequency Flood in the Koular Watershed

Cheikh Tidiane Wade

Abstract

The salt-polluted soils in the Koular watershed are estimated at 110 hectares and are located on the right bank of the watershed near the Koular-Keur Saloum Diane lateritic track, which contains a bridge that is the only outlet for the flow of salt water into the watershed. This bridge could be chosen for the construction of the anti-salt dike considering a flood with a ten-year frequency estimated at 28.77 m3/s to anticipate disasters.
