Now that’s Managed Aquifer Recharge!

Recent footage doing the rounds on social media and the news of the damage to Darling Cellars caught the eye of some of Umvoto’s wine enthusiasts. While beer has long been known to be an occupational hazard of geologists, at Umvoto wine is right up there. Situated in Muizenberg, Cape Town, Umvoto’s location has nurtured […]

MSc for Mkali: hydrogeological characterization using remote sensing

Umvoto’s Andrew Mkali (Junior Environmentalist) recently passed his MSc entitled “Developing a hydrogeological conceptual model for subterranean groundwater control areas using remote sensing techniques”. Andrew’s study at the University of the Western Cape’s Environmental and Water Science unit was under the supervision of Drs. Thokozani Kanyerere and Kevin Pietersen. In his study Andrew described the […]

Groundwater monitoring of the Cape Flats Aquifer

Quarterly groundwater monitoring of the Cape Flats Aquifer (CFA) is undertaken by Umvoto Africa geologists and hydrogeologists to build up a baseline prior to any large-scale abstraction and managed aquifer recharge (MAR). Wellfields are spread across the CFA targeting the thickest portion of the aquifer within the paleochannel (old river channel). Some wellfields are located […]

Google Earth Engine: a smarter way to make false colour composites

False Colour Composites (FCC) What do you do when you need to map large features in difficult to reach places? You use satellite imagery of course. Satellite imagery is great, it reveals insights that would otherwise go unnoticed during geological field mapping by allowing you to see Earth’s surface in new ways. At Umvoto, our […]

Kirsty’s MSc on 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 is extensively used for agriculture practices that can potentially lead to groundwater storage depletion, which threatens groundwater sustainability. Groundwater models are needed to develop an understanding of the complex, interdependent relationships occurring in a groundwater system. Groundwater levels represent the response of an aquifer to changes in storage, recharge, discharge, […]

The Cape geologist’s guide to lunch spots

A team of Umvoto geologists recently set out for four days to conduct field mapping along a major fault network within the Steenbras area. The fault network crosscuts through rocks of the Malmesbury and Table Mountain Groups, with the latter being targeted for groundwater development as part of the City of Cape Town’s New Water […]

Big data and transboundary groundwater resource management

Transboundary groundwater resources Water does not adhere to the strict political boundaries set by people. Just as some rivers flow through National boarders, the same is true for aquifers that store groundwater. Having different governments and organisations utilising these transboundary groundwater sources can make their management complicated and often unsustainable. One such example is the […]

Fractured rock aquifers: on the importance of springs

Recently some of Umvoto’s geologists and hydrogeologists went on a hunt for discharge points (groundwater-fed springs) along a large-scale fault network that cuts through the Table Mountain Group (TMG) fractured aquifers. This was in connection with a project that Umvoto is involved in with the City of Cape Town that was launched towards the end […]
