Flood Recharge Into Alluvial Aquifers
Along Western Namibia Rivers - CDR

This project investigates the relationship between surface water and the recharge of alluvial desert aquifers.

The study aims to develop a conceptual model of the recharge process by combining:

a geomorphic assessment of ephemeral channels,
palaeoflood hydrology tools to reconstruct the long-term flood frequency regime,
continuous monitoring of water and temperature profiles through the shallow and deep alluvial vadose zone, and
continuous monitoring of the groundwater stage and development of a conceptual model of the recharge processes.

This information will be integrated with an ongoing study on the critical condition required for vegetation to develop and be sustained along the flood stream channel.
 

Surface floodwater is not considered a sustainable water resource, both natural ecosystems and human societies exploit this scarce water source from underlying alluvial aquifers to maintain life in arid lands.
