Measurement of the Bulk Flow and Transport Characteristics of Selected Fractured Rock Aquifer Systems in South Africa
Expanded Title:Geological formations are complex features resulting from geological, mechanical, and physico-chemical processes occurring over a very wide range of length scales and time scales. Characterisation of fractured rock environments and especially secondary aquifers is extremely challenging. One of the major challenges is the ability to measure the bulk flow and transport characteristics of fractured rocks on a range of practical scales. These issues have considerable practical importance in groundwater management. The estimation of regional transmissivity values carries the burden in that if the regional transmissivity values for an area are overestimated, that inadequate provision of water would be made for water supply to the local community. The focal point of this study is to evaluate methodologies for use in converting bulk flow properties from a local perspective into parameters that could be applied on a regional level. Thus the critical issue of this study was to determine methods that yielded representative transmissivity values in a heterogeneous aquifer setting.
