Role of regional scale dykes in the flow of groundwater in the Otavi Mountainland karst aquifers
The work presented relates to the influence of regional scale dykes in groundwater flow in karst aquifers of northern Namibia’s Otavi Mountainland around the towns of Tsumeb, Otavi and Grootfontein. The aquifers are well studied and are an important water source locally and for populated central areas of the country during drought. The area has parallel, eastwest trending elongated valleys and ranges shaped by the underlying synclines and anticlines of folded carbonate units of the Damara Supergroup.
