Groundwater management measures
Geochemical investigations to improve the prediction of mine water impacts: A case study in the Elandsfontein Aquifer System, West Coast.
The impact of the future closure of the KROPZ phosphate mine in the West Coast on the various potential receptors including the underlying Elandsfontein Aquifer System (EAS), Langebaan Lagoon (RAMSAR-site) and wetlands were assessed. This abstract/paper describes the geochemical characterization and management options related to the waste streams from the mining activity, to assess the post closure contribution to groundwater flow from the mine towards potential receptors.
eSymon - An Innovative Solution to Monitoring Data Management
The year 2020 will forever be synonymous with the Covid-19 pandemic and the immeasurable impact it has had on all our lives. During this time, there was one avenue that reigned supreme: technology. Whether it was Zoom calls or Netflix, online consultations or video conferencing at work, technology took charge. In light of this, GCS (Pty) Ltd started exploring ways that technology could assist with the most common problem identified in the Water and Environmental sectors, which is the management of large volumes of geodata. Thus, the invention of eSymon.
Diamonds on the soles of their feet: groundwater monitoring in the Hout Catchment, Limpopo
We present findings from a current project in the Hout Catchment, Limpopo Province in South Africa, In grounding the discussion, we propose a citizen science framework that builds on ideas of the living lab, trust and research integrity. The idea of research integrity is not only about ethics but also about methods and we propose participatory methods that are inclusive, just and fair.
The Application of Machine Learning for Groundwater Level Prediction in the Steenkoppies Compartment of the Gauteng and North West Dolomite Aquifer, South Africa
Groundwater in the Steenkoppies compartment of the Gauteng and North West dolomite aquifer is extensively used for agricultural practices that can potentially lead to groundwater storage depletion, threatening groundwater sustainability in the compartment. Groundwater levels represent the response of an aquifer to changes in storage, recharge, discharge, and hydrological stresses.
Hydrogeological modeling of a coastal wetland: The development of a steady-state numerical groundwater flow model for Rietvlei Wetland, Cape Town
The Rietvlei Wetland, located in the Western Cape of South Africa is well recognised for harbouring numerous bird species, and is ranked the 6th most important coastal wetland in the South-western Cape. Researchers perceive that the wetland could be threatened by the growing drought hazards, and increased water demand in Cape Town. The extent of the effects is however unquantified and unknown.
