The role of ground water in Sub-Saharan Africa
(Wiley-Blackwell, 2010)Although water resources managers speak of a water crisis in Africa, the management of ground water has to date not featured strongly in national and regional African water agendas. Examination of the physical environment of ... -
Salinity of irrigation water in the Philippi farming area of the Cape Flats, Cape Town, South Africa
(Water Research Commission, 2013)This paper explores the nature, source and spatial variation of the salinity of water used for irrigation in a coastal urban farming area in Cape Town, South Africa, where water from the Cape Flats aquifer is drawn into ... -
Sandstone reservoir zonation of the north-western Bredasdorp Basin South Africa using core data
(Elsevier, 2021)This study delineates sandstone reservoir flow zones in the north-western Bredasdorp Basin, offshore South Africa, using conventional core porosity and permeability data. The workflow begins by integrating sedimen- tology ... -
Scenarios analysis using water-sensitive urban design principles: A case study of the Cape Flats Aquifer in South Africa
(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 ... -

Shale-gas potential from Cretaceous succession in South Africa’s orange basin: insights from integrated geochemical evaluations
(Taylor & Francis, 2022)Shale sediments were collected from four Cretaceous stratigraphic units across four explorations well locations in South Africa’s Orange Basin and analysed to determine organic-matter characteristics, such as amount, ... -
Snow impact on groundwater recharge in Table Mountain Group aquifer systems with a case study of the Kommissiekraal River catchment South Africa
(Water Research Commission, 2005)Snowmelt in the mountainous areas of the Table Mountain Group (TMG) in South Africa is believed to be one of sources of groundwater recharge in some winter seasons. This paper provides a scientific assessment of snow ... -
Source rock evaluation of Afowo clay type from the Eastern Dahomey Basin, Nigeria: Insights from different measurements
(Springer Nature, 2020)The Cretaceous Afowo Formation in the Eastern Dohamey Basin is characterized by an admixture of lithofacies ranging from sandstones, claystones, shales, clays, sand/shale, and sand/clay intercalations. The sandy facies, a ... -
Spatial characterisation of vegetation diversity in groundwater-dependent ecosystems using in-situ and sentinel-2 msi satellite data
(MDPI, 2022)Groundwater-Dependent Ecosystems (GDEs) are under threat from groundwater overabstraction, which significantly impacts their conservation and sustainable management. Although the socio-economic significance of GDEs is ... -
Spatial clustering of vegetation fire intensity using modis satellite data
(MDPI, 2022)This work analyses the spatial clustering of fire intensity in Zimbabwe, using remotely sensed Moderate Resolution Imaging Spectroradiometer (MODIS) active fire occurrence data. In order to investigate the spatial pattern ... -
Spatial monitoring and reporting tool (smart) in mid-Zambezi valley, Zimbabwe: Implementation challenges and practices
(Wiley Open Access, 2021)Biodiversity monitoring and data-management technologies can enhance the protection of persecuted species, such as African elephants (Loxodonta africana), through providing management-relevant information. Implementing these ... -
Spatiotemporal green water dynamics and their responses to variations of climatic and underlying surface factors: A case study in the Sanjiang Plain, China
(Elsevier, 2023)The Sanjiang Plain (SJP), located at the confluence reaches of the Heilong, Songhua, and Wusuli Rivers in Northeast China. his study aimed to quantify the effects of varying climate and land-use/land-cover (LULC) dynamics ... -
Spatio–temporal variation of vegetation heterogeneity in groundwater dependent ecosystems within arid environments
(Ecological Informatics, 2022)Climate change, land cover change and the over–abstraction of groundwater threaten the existence of Groundwater-Dependent Ecosystems (GDE), despite these environments being regarded as biodiversity hotspots. The vegetation ... -
Spectral classification, mapping and physical habitat implications of a riparian invasion by Tamarix ramosissima Ledeb. in the Touws River, Klein Karoo, South Africa
(Taylor and Francis Group, 2022)This paper investigates the invasion of a reach of the Touws River by the deciduous alien tree Tamarix ramosissima Ledeb. (Pink Tamarisk, Saltcedar). The objectives of the paper were to investigate ... -
Static reservoir modeling using stochastic method: A case study of the cretaceous sequence of Gamtoos Basin, Ofshore, South Africa
(Springer, 2021)Gamtoos Basin is an echelon sub-basin under the Outeniqua ofshore Basin of South Africa. It is a complex rift-type basin with both onshore and ofshore components and consists of relatively simple half-grabens bounded by ... -
Strength estimation of evaporitic rocks using different testing methods
(SpringLink, 2019)Rock strength is defined as the limit of the ability of a rock to resist stress or deformation without breaking. Testing methods recommended by ISRM (International Society of Rock Mechanics) and ASTM (American Standards ... -

Sustainable groundwater use, the capture principle, and adaptive management
(Water Research Commission, 2006)The purpose of this paper is to review the case for using ‘capture’ rather than recharge as the conceptual basis for sustainable groundwater use in South Africa. Capture refers to the sum of the increase in recharge and ... -
A synthesis of past, current and future research for protection and management of papyrus (Cyperus papyrus L.) wetlands in Africa
(Springer Verlag, 2014)Papyrus wetlands (dominated by the giant sedge Cyperus papyrus L.) occur throughout eastern, central and southern Africa and are important for biodiversity, for water quality and quantity regulation and for the livelihoods ... -
A systematic review on the use of remote sensing technologies in quantifying grasslands ecosystem services
(2022)The last decade has seen considerable progress in scientific research on vegetation ecosystem services. While much research has focused on forests and wetlands, grasslands also provide a variety of different provisioning, ...
