Objectif
To produce and test an integrated suite of software to allow assessment of natural groundwater recharge at range spatial/temporal scales. Combine hydro processing models with GIS tech to produce management tool based on PC technology.

Descriptif
The sequence of droughts in Africa over the last two decades has highlighted the vulnerability of many of the continent’s rural population to the decline of groundwater resources. This decline has been as a result of both man’s actions and natural variations. A reliable estimate of groundwater recharge is vital in order to manage the resources. The requirement is for a management tool which can be used to investigate a variety of scenarios at local and regional scales and also has an ability to provide geographic analysis and data visualisation. A modern methodology using models based on process studies is needed to predict recharge and a distributed model is required in order to include spatial variations.
