Abstract
At the onset of this research programme it became apparent that there is a dearth of
research studies focusing on the groundwater resources of the region. As a result, a
conceptual representation of the hydrogeological system (i.e. specific aquifer systems,
groundwater flow regime, etc.) for the perceived problematic aquifer systems in the
Namaqualand region did not exist. The research project contributes significantly to
conceptual representation of the aquifer system, in particular a quantitative understanding
of the regions' groundwater resources in terms of its hydrochemical development and the
construction of a groundwater flow model at regional scale as well as at a local scale.
The groundwater resources for the Namaqualand region are developed predominantly in
the basement rocks. The infiltration and flow of water is controlled by the prevailing
complex fracture network and can vary in space and time. Such observations relate to
structurally controlled flow systems and varying water chemistry amongst closely spaced
fracture systems.
