	The Africa Water Atlas provides a useful overview of water resources in Africa, with particular focus on the social context of water resource development. The main transboundary surface water basins and aquifers are summarised, and the Atlas contains a short profile on the water resources of each country.

The drainage thematic layer contains a drainage network that classifies streams and rivers into perennial and non-perennial. This classification has been spatially joined with the Rivers of Africa dataset to give an indication of where rivers are likely to be flowing all year round.
