ABSTRACT

The study highlights the potential recharge areas of the aquifers of the Department of Aboisso for an adequate and rational management of their use. The methodology used consisted in the identification of parameters (land use, soil types, drainage density, slope, induced permeability and alteration thickness) allowing infiltration and their expression as thematic maps. A weighting of these parameters was made by the multicriteria analysis method of Saaty. The integration to GIS conducted to elaborate the map of the potential recharge area of the aquifers for the Department of Aboisso. It brings to light five recharge level classes (bad: 20%; mediocre: 19%, medium: 45%; good: 15% and very good: 1%) in the study area. That map reveals the dominance of good recharge areas covering 61% and practically all over the studied area. They are generally characterized with gentle slopes coupled with mosaics of cultivations and forests, and high induced permeability allowing better infiltration. The zones of low recharge cover 39% of the department’s area, and are mainly located in urban areas inside the streams. This study exhibited that the land use is the preponderant parameter influencing the recharge in base area. This map could be considered as an excellent support for all kinds of activities especially to implement planning in the Department of Aboisso, the setting up of drilling broadbands and the choice of future sites for landfills or landfill of wastes to protect groundwater from any pollution.
