Karim Sami

Principal Geohydrologist/Tshwane

Mr. Sami is a specialist on groundwater resources. He is a recognised expert in surface-groundwater interactions and has developed the surface-groundwater interaction software used in the WRSM 2000 model (Pitman Model), which is used internationally for rainfall-runoff modelling. The software has been used to evaluate groundwater resources nationwide on a Quaternary Catchment scale for the GRAII groundwater resource assessment project, and the impact of groundwater abstraction on surface water resources. The model has received widespread application in the Letaba, Luvuvhu, Mhlatuze, Crocodile West, Mokolo and Olifants River catchments, and in several dolomitic compartments.

He is also well versed in the evaluation of the sustainable yield of boreholes and has developed and published methodologies and software in this regard. The methodologies have been tested and verified in numerous fractured rock aquifers.

He has pioneered the use of tectonics and structural analysis for groundwater exploration. The techniques have been used to establish high yielding boreholes in regions previously considered to be low yielding, such as the Limpopo Mobile Belt, Barberton Greenstone belt, and the Natal Metamorphic Province.

He has modeled groundwater resources, developed dewatering and land use management plans, for Tshwane and Capricorn Municipalities; Kumba, PPL and Coal of Africa mines; the Department of Trade and Industry, amongst others.
