Impact of irrigation with gypsiferous mine water on the water resources of parts of the upper Olifants basin.
(2007)The generation of large quantities of mine wastewater in South African coal mines and the needs for a cost effective, as well as an environmentally sustainable manner of mine water disposal, have fostered interests in the ... -
Influence of land cover degradation on the water balance of the Northern Drakensberg high altitude mesic grasslands, South Africa.
(2022)Mountainous regions provide vital ecosystem services, such as water provisions to low land areas. However, these regions are also considered sensitive to the effects of environmental change, due to their high levels of ... -
Integrating hydro-climatic hazards and climate changes as a tool for adaptive water resources management in the Orange River Catchment.
(2012)The world’s freshwater resources are being placed under increasing pressure owing to growth in population, economic development, improved standards of living, agricultural intensification (linked mainly to irrigation), ... -
Mainstreaming adaptation to climate change into decision making in the water sector : concepts and case studies from South Africa.
(2015)Abstract available in Pdf file. -
Performance of irrigation and water management systems in the lowveld of Zimbabwe.
(2004)In order to assess the performance of water management approaches and irrigation systems used by the sugar industry in the Lowveld of Zimbabwe, a sugarcane yield and irrigation systems simulation model was developed. The ... -
Rainwater harvesting systems and their influences on field scale soil hydraulic properties, water fluxes and crop production.
(2009)South Africa, in common with many parts of Sub-Saharan Africa, is facing increasing water shortages. Limited available water arising from a low and poorly distributed rainfall, must supply domestic, agricultural, industrial ... -
Refinement of modelling tools to assess potential agrohydrological impacts of climate change in southern Africa.
(2001)Changes in climate due to anthropogenic influences are expected to affect both hydrological and agricultural systems in southern Africa. Studies on the potential impacts of climate change on agrohydrological systems had ... -
Transient pressure waves in hillslopes.
(2013)Previous studies found that during a rainfall event, pre-event water, which exists in the catchment before the event, may appear in significant amounts in the stream stormflow hydrograph. Pre-event water is predominantly ... -
Water temperature and fish distribution in the Sabie River system : towards the development of an adaptive management tool.
(2003)Water temperatures are a fundamental water quality component, and a key abiotic determinant of fish distribution patterns in rivers. A river 's thermal regime is the product of a multitude of thermal drivers and buffers ... -
Water-use dynamics of alien plant invaded riparian forests in South Africa.
(2018)In South Africa the invasion of riparian forests by alien trees has the potential to affect the country’s limited water resources. It is difficult for government initiatives, such as the Working for Water (WfW) alien ... -
Wetland geomorphology and floodplain dynamics on the hydrologically variable Mfolozi River, KwaZulu-Natal, South Africa.
(2008)Wetlands in southern Africa can be considered a rarity, forming despite a regional negative water balance and a continental background of wide scale incision. These particular characteristics lead to southern African ...
