Other Events

This study is about the assessment of the isotope signature of rainfall events between November 2016 and October 2018 in Johannesburg, South Africa. Additionally, the study uses the Hybrid Single Particle Lagrangian Integrated Trajectory model (HYSPLIT) to assess the moisture sources and trajectories for rainfall events of extreme isotopic signatures.

Following the Talk by Helen Seyler, hosted by the Western Cape Branch on 28 January 2021, Zaheed will further extrapolate on the research into the applicability of machine learning for the forward prediction of groundwater levels and flow regime using results from the dolomite aquifers in South Africa.

Localizing regional-scale groundwater big data using machine learning: A case study of the Ramotswa/NW/Gauteng Dolomites

FEFLOW is widely recognised as a comprehensive software package for subsurface flow and transport simulation. FEFLOW’s unique meshing capabilities (structured and unstructured) allows for the highest degree of flexibility to account in detail for the most simple to complex geometrical configurations. The software is used by leading research institutes, universities, consulting firms and government organisations all over the world.

This course, provided by Colin Rice, will provide newly qualified geologists that have had little or no exposure to drilling operations, with a fundamental understanding of selected aspects of a drilling operation.

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.

The vadose zone stretches from the land surface to the groundwater table, where moisture in intergranular pore space and rock defects occurs at variable water saturation and at negative pore-water pressures.

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.

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.
