Arid regions in Southern Africa experience severe challenges to supply clean water in times of continuously growing water demands and climate change. The SeeKaquA project aims at exploring two deep aquifer systems in Namibia and Zambia with the semi-airborne electromagnetic methods to consider these water resources as alternatives to surface water resources for sustainable water management. Within the project, terratec will acquire a modern SAEM-System and perform SAEM- and TEM measurements with the project partners.
