Characterization and Aquifer Functioning System of Haraz Al Biar (North Chari Baguirmi)

Article Info Haraz Al Biar (Northern Chari-Baguirmi) is located in the semi-arid zone, limited to the north by Lake Chad and on the west by Chari-Logone. The study of Haraz Al Biar aquifer system aims to improve its knowledge for the sustainable managementof groundwater resources. In the study area, water sampling campaigns were realized. These samples have been the subject of the study of hydrodynamic and hydrochemical parameters of the aquifer system. The piezometric data show that the transfer of water from Lake Chad is hydraulically possible because the level of the lake is above the static level of the water table. The chemical data allowed to distinguish the difference between bicarbonate and sulphate facies.
