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 This information is outdated.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.

Hydrogeology

This section provides a summary of the hydrogeology of the main aquifers in the Central African Republic. More information is available in the report [ADD LINK UN] (1988) (see References section, below).

The hydrogeology map shows a simplified version of the type and productivity of the main aquifers at a national scale (see the Aquifer properties resource page for more details).
