hydraulic parameters

In this study the groundwater resource in the Tsineng area in the Northern Cape Province was assessed in terms of the volumes of water that may be sustainably removed from the aquifer system, and the quality of the available groundwater. A strong emphasis was placed on the use of airborne and ground geophysical techniques to gain a better understanding of the geological and geohydrological conditions in the study area.

The assumed interconnection between palaeochannels and subsurface water resources is described. This paper (poster) discusses the different methods that can be used to indicate the significance of palaeochannels into groundwater recharge. Hydraulic parameters such as permeability and transmissivity of the layer underlying the palaeochannel act as the main dependents of groundwater recharge on palaeochannels.

Hydrogeologists have moved past merely investigating for water supply and quantification of sustainable yields. In the 21st century, and with rapid urbanisation and climate change, hydrogeologists are expected to work in cross-disciplinary fields of geochemistry, aquatic biodiversity, surface water – groundwater interaction, groundwater economics, law and management. In addressing important hydrological parameters such as recharge, recharge rates, advection of contaminants and interflow, the role of the vadose zone becomes increasingly important.
