Fieldwork & the focus on geophysics AT Receiver - Pseudo-Science or a method worth investigating. The Audio Magnetotelluric (AMT) signal is generally in the range of 1Hz - 20 kHz with its origin as spherics created by thunderstorms, magnetospheric noise, seismic events, etc. Historical AMT monitors up to five channels at each station, namely Ex Ey Hx Hy Hz. The EM field is a plane wave perpendicular to the ground surface, away from the field source.

  • Microplastics
  • Stormwater

Microplastics are tiny particles (smaller than 5mm) found in the environment. They are synthetic polymers and are either produced in its microform to be utilized in personal care products and detergents or disintegrated from larger plastics or synthetic materials (e.g. recycled polyethylene terephthalate items), respectively known as primary or secondary microplastics.

  • Groundwater
  • Water use
  • Borehole
Groundwater is not private property, and the use of groundwater requires a water use license or a general authorization. This is imperative for most environmental impact assessments, requiring even ongoing monitoring for the foreseeable future.

  • Groundwater
  • Borehole
Public domain borehole information in South Africa is generally stored in the National Groundwater Archive (NGA) and the Groundwater Resources Information Project (GRIP) databases of which both are centralized databases. The GRIP database is updated by the Department of Water and Sanitation, but only covers one of the nine provinces. The NGA on the other hand covers the entire country, however, there is a backlog of borehole information that needs to be captured, and it has limited time-series data.

  • Groundwater storage
Alongside the effects of climate change and anthropogenic factors, natural climate cycles have considerable impacts on the hydrologic cycle. In this study, we look at how global climatic oscillations cycles, like El Niño–Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) affect total water storage and groundwater storage in the Orange-Senqu River Basin by analysing two large aquifers: the Stampriet Transboundary Aquifer System (STAS) shared between Botswana, Namibia and South Africa, and the Karoo Sedimentary Aquifer shared between Lesotho and South Africa.

  • Geohydrological
  • 3D models
Recent trends in mining and exploration are set to further accelerate the demand and growth of 3D geological modelling software. These trends include the inevitable increase in cost per ton of resource and global economic slowdowns. These require companies to constantly cost-cut during extraction and to improve resource delineation. Add to this the trend that new discoveries are deeper and in more structurally-complex setting, and it’s apparent that a great deal of attention needs to be focused on getting the geometry of a deposit, as early as possible in the exploration and mining value chain, correct.

  • Climate change
  • Groundwater
TALK ABSTRACT  It’s commonly accepted that climate change will be experienced though water, particularly in developing countries. Several studies relating to the impacts of climate change on surface water have been undertaken while very little research exists on the potential impacts on groundwater.

  • Water treatment
  • Plants
  • Water supply
Small water treatment plants are defined as water treatment systems that have to be installed in areas which are not adequately serviced and do not normally fall within the confines of urban areas. They are therefore mostly used in rural and peri-urban areas and include chlorination plants for water supplies from boreholes and springs, small treatment systems for rural communities, treatment plants of small municipalities and treatment plants for establishments such as rural hospitals, schools, clinics, forestry stations, etc.

Science is a living document; it grows and expands as more information becomes available and our knowledge grows. It makes use of hypothesis, experiments, observations, and measurements. Groundwater scientists have a difficult task. They work in a system that is not visible, and they cannot take it into a laboratory to study. They use geophysical methods and drill boreholes to get an idea of the groundwater system that they are studying.

In the Karoo coalfields, mining operations that release acid mine drainage (AMD) are threatening groundwater resources. An important parameter controlling the extent and severity of AMD impacts is the natural attenuation of rocks in response to introduced of AMD. Very little is known about such responses for Karoo rocks in saturated and unsaturated conditions, a research gap filled by this paper. Laboratory column leach experiments were used to study the responses of different rock types from Witbank, Ermelo and Highveld coalfields of South Africa. .

One thing that we all know about water is that it always finds a way to get over, under, or through any obstacle that may stand in its way. It is no surprise then, that when we realized that the South African government proclamation against gatherings of more than 100 people meant that our meeting in June would have to be canceled, our amazing team of organizers put the #AllHandsOnDeck mindset into action. The result is that WISA2020 is definitely going ahead with the same excellent sessions and – pending confirmation – the same excellent speakers. And with the extra time we have, we will be able to make sure that our conference is bigger and better than ever before.

About the Talk: Fundamental to the definition of groundwater availability and the management of any aquifer is an understanding of the changes in groundwater levels and storage, recharge, and groundwater discharge to surface water, when the aquifer is pumped. This understanding forms the foundation for the determination of limits of future abstraction and thresholds of unacceptable impact, and provides a tool against which to compare future datasets and make groundwater management decisions.

The Vadose Zone in Engineering Geology and Hydrogeology - Research by UP Geology Join us for a FREE one-hour series of talks on recent research on unsaturated hydraulics and the role of the vadose or unsaturated zone in engineering geology and hydrogeology. The Department of Geology has for the past decade focused on how the soil and rock between land surface and the phreatic or saturated zone behave with respect to highly variable moisture contents. We contributed to knowledge on variably saturated flow through soil, rock defects, karst, and the interfaces between these media.
