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 […]
examples of the NNAR ability to predict groundwater levels from two boreholes in the Steenkoppies aquifer.

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, […]

Contamination and Remediation

Umvoto Africa monitors the water quality as part of the City of Cape Town New Water Programme, with a focus on surface water and groundwater quality. This includes the development of monitoring plans, laboratory oversight, data analysis and interpretation. Umvoto Africa has sampled groundwater for assessment of suitability for potable supply, as well as surface […]

Air Quality Surveillance and Geothermal Risk Mitigation

Umvoto Africa constructed, installed, manages and monitors air quality sensors via a fully automated GPRS-linked weather station for the Tulu Moye Geothermal Power Plant in central Ethiopia. While several noxious gases (nitric oxide, sulphur dioxide, carbon monoxide and ozone) are monitored, hydrogen sulphide is especially important for the geothermal plant and strict adherence to World […]
Various Private:Public Client Groundwater Assessment:Development Projects

Various Private/Public Client Groundwater Assessment/Development Projects

Umvoto Africa has undertaken numerous smaller groundwater assessment (including desktop studies, hydrocensus, geophysics and borehole siting) and groundwater development (including drilling, testing, hydrochemical sampling and analysis, yield analysis and water use licence application) work for various private and public clients. These include: Residential estates e.g. Faircape Group (Tokai Estate, Onrus Manor, Noordhoek Manor), Klein Slangkop […]
