SUMMARY
In Côte d'Ivoire, the problem of access to drinking water is particularly acute because the impoundments built for supplying water to populations are no longer properly served and are subject to very strong eutrophication. Hence the use of groundwater. This study aims at assessing the Bandama watershed’s groundwater potentialities in order to identify high productivity drilling sites. The methodological approach is based on the multicriteria analysis methods and GIS. Classes with good and excellent water potentiality are the most dominant, representing 52% of the basin. Despite this good water potentiality, the groundwater of the Bandama watershed are difficult to access. The different areas suitable for the implementation of large flows structures have been mapped and can be used as aid tools to explore cracked environments.
