Sampling of water from the drilling Abouabou was used to measure the following physico-chemical parameters such as pH, electric conductivity, temperature, turbidity, content of silica, chlorides, aluminum, zinc, magnesium, manganese, copper, ammonium, sulfates, nitrates, nitrites, phosphates and fluorides.
Drilling Abouabou aims to increase water supply capacity of the city of Abidjan and its surroundings. Analysis of physical parameters indicates a neutral pH average of 6.8 ± 0.16 units and an average temperature of 28.83 ± 0.7 ° C. The water is highly mineralized and low in suspended solids with a conductivity average of 2990.83 ± 31.55 μS.cm-1 and an average turbidity 0.862 ± 0.91 NTU. The chemical analyzes, in turn, reveal a significant salinity making the water unsuitable for human consumption without pretreatment. A strong correlation is shown between the contents of chlorides and the physicochemical parameters such as temperature, pH, turbidity, content of iron and manganese. This shows that the drilling of water quality is mainly governed by the chloride contents. The geographical location of the structure near the Atlantic Ocean, deep character and a captive of the web (Continental Terminal) and the absence of solid salts (evaporites) in the formations traversed by drilling suggest two mechanisms either a seawater intrusion, a salinity heritage.

The objective of this study is to better understand the functioning of a river system in the context of sustainable management of water resources. To better understand this functioning, hydrogeological modelling of the watershed of White Bandama is necessary. The methodological approach is derived from a process comprising two steps. The results are derived from a process comprising two steps. The first step consists in the mapping of the physical descriptors of the watershed that affect hydrological processes, such as topography, drainage patterns, land cover and soil type. Using PHYSITEL and a Digital Elevation Model (DEM), slope and orientation maps of the facets are derived and then coupled to the water system for the characterization of the internal hydrographic structure of the watershed. Supervised classification of Landsat TM dating from 1987 to 1993 led to the mapping of land use. The second step consists in combination of established thematic maps. The combination of these thematic maps is used to determine with HYDROTEL the dominant type of soil and land use by Relatively Homogeneous Hydrological Units (RHHU) representing small sub-watersheds.
