Africa Groundwater Atlas >> Hydrogeology by country >> Hydrogeology of the Central African Republic

Most of the textual information on this page was taken from the chapter on the Central African Republic in the report‘Groundwater in North and West Africa’ (UN 1988). This information is outdated. If you have more recent information on the hydrogeology of the Central African Republic, please get in touch.
