Abstract:
Despite abundant rainfall (2000 mm year-1) and the presence of many rivers, the Aboisso area is faced with a crucial shortage of drinking water. Water flow rates generally remain low, ranging from 0.25 to 11 m3 h-1. This study aims to identify potential groundwater zones (GWPZ). Both Geographical Information System (GIS) and multicriteria Analysis (MCA) were used in combination to resolve to this problem. The linear combination of the weights, based on pair wise comparisons was used. This method allowed for combining a set of parameters to express the accessibility, exploitability and availability of groundwater resources. This led to the mapping in support of the implementation of future water points. The results show that, in spite of good groundwater (61%) availability, coupled with easy accessibility (81%), the resource remains moderately exploitable (50%). The most suited areas to locate wells represented 59% of the Aboisso area.
