Abstract
The resources of Basement aquifers in Victoria Province, Zimbabwe are largely dependent on rainfall recharge but no direct evidence for recharge in the form of borehole hydrographs is available. Estimates of recharge have been made by three methods: river baseflow analysis; hydrochemical analysis of groundwaters and simulation modelling. All three methods produce consistent results, suggesting that recharge amounts to between 2–5% of annual rainfall. Under such circumstances, which are widespread in Africa, it is essential to make resource estimates based on many years of data, otherwise over or under estimates are likely because of the considerable annual variation in rainfall.
