BetaBetaDataset
To provide quantitative continent-wide map of aquifer storage estimates of groundwater resources.
The dataset covers a 5 km resolution grid that presents groundwater storage in Africa (in mm). This parameter was estimated by combining the saturated aquifer thickness and effective porosity of aquifers across Africa. For each aquifer flow/storage type an effective porosity range was assigned based on a series of studies across Africa and surrogates in other parts of the world.
Fixed map displaying groundwater storage for Africa based on the effective porosity and saturated aquifer thickness. This is expressed as water depth in millimetres.
This data is derived from estimates by combining the saturated aquifer thickness and effective porosity of aquifers across Africa.
