Leveraging Google Earth Engine platform to characterize and map small seasonal wetlands in the semi-arid environments of South Africa
Gxokwe, Siyamthanda; Dube, Timothy; Mazvimavi, Dominic (Elsevier, 2021-07)Although significant scientific research strides have been made in mapping the spatial extents and ecohydrological dynamics of wetlands in semi-arid environments, the focus on small wetlands remains a challenge. This is ... -

Multispectral remote sensing of wetlands in semi-arid and arid areas: A review on applications, challenges and possible future research directions
Gxokwe, Siyamthanda; Dube, Timothy; Mazvimavi, Dominic (Remote Sensing, 2022)Wetlands are ranked as very diverse ecosystems, covering about 4–6% of the global land surface. They occupy the transition zones between aquatic and terrestrial environments, and share characteristics of both zones. Wetlands ... -
Scenarios analysis using water-sensitive urban design principles: A case study of the Cape Flats Aquifer in South Africa
Gxokwe, Siyamthanda; Xu, Yongxin; Kanyerere, Thokozani (Springer, 2020)A feasibility assessment was undertaken on the application ofwater-sensitive urban design (WSUD) for the Cape Flats Aquifer in Cape Town, South Africa, at the local scale. The study contributes towards the planning of ... -

Using cloud computing techniques to monitor long-term variations in ecohydrological dynamics of small seasonally-flooded wetlands in semi-arid South Africa.
Gxokwe, Siyamthanda; Dube, Timothy; Mazvimavi, Dominic; Grenfell, Michael (Journal of Hydrology, 2022)Wetlands in drylands have high inter- and intra-annual ecohydrological variations that are driven to a great extent by climate variability and anthropogenic influences. The Ramsar Convention on Wetlands encourages the ...
