Talk: Machine Learning modelling techniques for groundwater availability in RSA Dolomites (GWD WCAPE)

28 Jan 2021

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. Given the complex nature of groundwater and the interdependent responses of the system to change, quantifying the relationship between the aquifer flow regime and abstraction, and determining the

Workshop: Vadose Zone Hydrology in Engineering Geology and Hydrogeology (UP)

19 Jan 2021

Brief Description View/ Download the full brochure The vadose zone stretches from 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. Theory in the occurrence and movement of water in unsaturated conditions in soil and rock media is developing, with improved understanding reducing the uncertainty in conceptualizing and characterizing these complex systems.  The vadose zone dictates how water exists and moves in the shallow subsurface. This, in terms of engineering geology, inevitably leads to volume change of ground, changes in the corrosiveness of

Talk: Building a puzzle: developing a groundwater conceptual model (GWD Central)

02 Oct 2020

TALK ABSTRACT 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. These become the building blocks – the puzzle pieces – that are used to develop the conceptual model. This is the hypothesis of the groundwater scientists. Fortunately,

Talk: Impacts of Climate Change on Groundwater: current state of research (GWD GAU)

27 Aug 2020

  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. Hence, this talk aims to discuss some of the current research with respect to climate impacts on groundwater. Various methods are proposed for estimating climate change impacts on groundwater, such as using hypothetical scenarios of progressive drying to assess stream flow sensitivity to drought, using MODFLOW to investigate projected effects of climate change on groundwater or

Online Talk (3): Principles of Efficient Gravel Envelope Well Design and Operation (GAKZN, GWD)

30 Jun 2020

The expectation of a water well is to provide a desired production rate at any given time.  This performance expectation has been expanded to not only providing the maximum production rate, but also for the well to operate at its highest efficiency. Both internal and external design and hydraulic factors must be accounted for during the design, construction, operation, and maintenance phases in order to maximize the well's production potential with minimum head losses. This presentation will highlight the critical components of the well design process and demonstrate how wells can be operated with greater water production and cost efficiency.

Professional Course: Vadose Zone in Engineering Geology and Hydrogeology (UP)

20 Feb 2019

The Vadose Zone: Variable Saturation in Engineering Geology and Hydrogeology Presented by the Department of Geology, University of Pretoria Variably saturated flow conditions are increasingly relevant to geotechnical and hydrogeological assessments. This is most evident in the so-called vadose zone that extends from land surface to the phreatic surface, and which is characterised by variably saturated hydrological systems mostly at negative pore water pressures. The Vadose Zone: Variable Saturation in Engineering Geology and Hydrogeology short course explores this zone which is fundamental in understanding the subsurface component of the hydrological cycle, emphasising processes such as evapotranspiration, interflow, and groundwater recharge.
