Development and assessment of an improved continuous simulation modelling system for design flood estimation in South Africa using the ACRU model.
(2019)An estimate of the risk associated with flood events is required to adequately design hydraulic structures and limit negative socio-economic impacts as a result of floods. The methods used to estimate design floods in South ... -

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 ... -

Ground and satellite-based assessment of hydrological responses to land cover change in the Kilombero River Basin, Tanzania.
(2013)Changes in land use and land cover are a global issue of concern, especially with regard to possible impacts on biophysical processes which affect the hydrological functioning of a system. Tanzania is no exception to ... -
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 ... -
Challenges in modelling hydrological responses to impacts and interactions of land use and climate change.
(2012)To meet society’s needs for water, food, fuel and fibre the natural land cover throughout the world has been extensively altered. These alterations have impacted on hydrological responses and thus on available water ... -
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), ... -
An assessment of canopy and litter interception in commercial and indigenous forests in the KwaZulu-Natal Midlands, South Africa.
(2011)Understanding of the hydrological cycle and processes such as interception span as far back as the times of the Renaissance, when Leonardo da Vinci (1452-1519) first described it. However, there remains a gap in the knowledge ... -
Development and evaluation of model-based operational yield forecasts in the South African sugar industry.
(2005)South Africa is the largest producer of sugar in Africa and one of the ten largest sugarcane producers in the world. Sugarcane in South Africa is grown under a wide range of agro-climatic conditions. Climate has been ... -
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 ... -
Assessment of agro-ecosystem sustainability across varying scales in South Africa.
(2005)Maize production plays an important socio-economic role in rural communities of the Highveld region of South Africa, yet it is becoming increasingly difficult to produce maize economically with current agricultural policy ... -
Assessment of the water poverty index at meso-catchment scale in the Thukela Basin.
(2006)The connection between water and human wellbeing is increasingly causing concern about the implications of water scarcity on poverty. The primary fear is that water scarcity may not only worsen poverty, but may also ... -
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 ... -
Characterisation of the hydrological processes and responses to rehabilitation of a headwater wetland of the Sand River, South Africa.
(2011)The erosion of headwater wetlands in the Sand River catchment, in the lowveld of north-eastern South Africa has led to a focus on their rehabilitation, both for livelihood security for those that use them for subsistence ... -
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 ...
