Assessing the role of water resources protection practice for sustainable water resources management: A review
(MDPI, 2022)Water resource protection is central to sustainable water supply management for human wellbeing and for the ecological ecosystem to flourish. This review paper focuses on highlighting the role of groundwater and surface ... -
Assessment of drinking water quality using metal index, degree of contamination and hazard indices on ground water sources in an agricultural tropical environment
(Informatics Publishing Limited, 2023)The study conducted in the dry and rainy seasons of 2019 assessed the levels of metals in groundwater sampled from boreholes and dug wells in Ikwo, southeastern Nigeria. Nine water samples were analysed for calcium, iron, ... -
Characterisation of hydro-geochemical processes influencing groundwater quality in rural areas: A case study of Soutpansberg region, Limpopo Province, South Africa
(MDPI, 2022)Groundwater is often the main or only source of fresh water supply in arid to semi-arid rural areas owing to decreasing rainfall patterns, reduced availability of surface water and socioeconomic activities. It is important ... -
A conceptual model for the development and management of the Cape Flats aquifer, South Africa
(Water Research Commission, 2010)This paper provides an integrated approach to the analysis of the geological, hydrological and hydrogeological characteristics of the Cape Flats: a coastal plain sand formed within the mountains of the Cape Town metropolitan ... -
Effect of temperature on microorganisms and nitrogen removal in a multi-stage surface flow constructed wetland
(MDPI, 2023)The effect of low temperature on microbial nitrogen metabolism in constructed wetlands has yet to be extensively investigated. In this study, we analyzed the effects of temperature changes on nitrogen-associated microorganisms ... -

Feasibility assessment of the application of groundwater remediation techniques in rural areas: A case study of rural areas in the Soutpansberg region, Limpopo Province, South Africa
(MDPI, 2022)Groundwater contribution towards human health and livelihood depends on the contaminants level in groundwater. Many people in rural communities are being exposed to waterborne diseases resulting from drinking untreated ... -
Near real time water quality monitoring of Chivero and Manyame lakes of Zimbabwe
(Copernicus Publications, 2018)Zimbabwe’s water resources are under pressure from both point and non-point sources of pollution hence the need for regular and synoptic assessment. In-situ and laboratory based methods of water quality monitoring are ... -
Oestrogen, testosterone, cytotoxin and cholinesterase inhibitor removal during reclamation of sewage to drinking water
(Water Research Commission, 2013)Namibia is the driest sub-Saharan country in Africa. Namibia’s capital, Windhoek, reclaims sewage water for domestic use at the Goreangab Water Reclamation Plant (GWRP). Risks associated with sewage effluent and reclaimed ... -
Policy implementation for water resources protection: Assessing spatio-temporal trends of results from process-based outcomes of resource-directed measures projects in South Africa
(MDPI, 2022)Governments are continuously developing strategies for policy implementation toward water resource protection. However, little is known about the practical application of such plans to test their effectiveness in policy ... -
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 ... -
Using the water balance approach to understand pool dynamics along non-perennial rivers in the semi-arid areas of South Africa
(Elsevier, 2022)The Touws River in the Klein Karoo region of South Africa Study focus: This study sought to improve the understanding of pool dynamics along non-perennial rivers (NPRs) by utilising the water balance approach to assess the ... -
Water quality prediction based on multi-task learning
(MDPI, 2022)Water pollution seriously endangers people’s lives and restricts the sustainable development of the economy. Water quality prediction is essential for early warning and prevention of water pollution. However, the nonlinear ... -
Waternet: A network for monitoring and assessing water quality for drinking and irrigation purposes
(IEEE, 2022)Water is a fundamental requirement for human, animal, and plant survival. Despite its importance, quality water is not always fit for drinking, domestic and/or industrial use. Numerous factors such as industrialization, ... -
Wetlands in drylands: Diverse perspectives for dynamic landscapes
(Springer, 2022)The United Nations Environment Programme (UNEP 1997) classifes global drylands according to an Aridity Index (AI), defned as the ratio between mean annual precipitation (MAP) and potential evapotranspiration (PET). ...
