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), ... -
Integrative policy instruments for implementing the National Water Act : a case study of the Mgeni Catchment.
(2013)South Africa experienced a paradigm shift with the introduction of the National Water Act in 1998 (NWA). Previously, water resource management was based on a centralized approach. Today, it is framed by the Integrated Water ... -
An investigation into sugarcane vehicle loading with respect to influences on overall transport efficiency.
(2011)The South African sugar industry ranks eleventh in size out of 200 sugar-producing countries; and continuous advancement is essential to ensure that this industry remains competitive. The transfer system from field to ... -
An investigation into the suspended sediment flux and dynamics of the Mgeni Estuary, Durban.
(2009)This dissertation focuses on both a hydrodynamic and geomorphological study of the Mgeni Estuary. Within the hydrodynamic study, the channel discharge, suspended sediment fluxes and estuary bed sediment characteristics and ... -
Investigation of the potential use of the root-zone storage concept in hydrological modelling under South African conditions.
(2019)Hydrological models are currently an accepted method used in determining the impacts of Streamflow reduction activities (SFRA) in South Africa. However, the limited availability of soils and rooting depth data create high ... -
Linkages between selected hydrological ecosystem services and land use changes, as indicated by hydrological responses : a case study on the Mpushini/Mkhondeni Catchments, South Africa.
(2014)Nature provides essential services to humans, including climate regulation, water provisioning and regulation. These so-called ecosystem services have economical, societal and environmental value. This research aims at ... -
Linking the hydrological, geomorphological and sociological aspects of wetlands in rural areas : a case study based in the Craigieburn wetland microcatchment in the Sand River catchment.
(2004)In many of the rural areas of South Africa local communities rely on wetland resources for daily living. For a symbiotic relationship to exist between these communities and the wetlands, the wetlands must be utilised in a ... -
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. -
A methodology for assessing irrigation practice in small scale community gardening.
(2001)The challenges facing small scale irrigation development in South Africa are varied and complex. This complexity is exacerbated by the many years of systematic neglect, in tandem with material and intellectual impoverishment ... -
Non point source pollution with specific reference to the Mkabela Catchment.
(2011)Non point source pollution (NPS) has long been the negated form of pollution within our natural systems. With an increase in the demand for quality crops and staple foods, there have been added pressures on water systems ... -
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 ... -
The potential impacts of up-scaled rainwater harvesting on ecosystem goods and services in the Potshini and Makanya catchments.
(2016)Water scarcity is fast becoming a global concern, with at least each continent facing water-related issues regarding quantity, quality and delivery. An estimated 8.8% of South Africans do not have access to potable water, ... -
The potential of micro-hydropower generation in the Inkomati River Catchment in Mozambique.
(2014)Hydropower is the leading source of renewable energy. It provides more than 97% of all electricity generated by renewable sources internationally. Small hydropower plants (SHPs) can be an alternative and a complement to ... -
Predicting emissions using an on-road vehicle performance simulator.
(2002)South Africa is coming under increasing pressure to conform to the rest of the world in terms of emissions regulations. The pressure is caused by a number of factors: international organisations requiring local companies ... -
Procedures for estimating gross irrigation water requirement from crop water requirement.
(2001)The goal of irrigation is to supply sufficient water for crop growth to all areas within a field. Therefore, the uniformity of application of irrigation water is of great importance. The objectives of this study were to ... -
Projected impacts of climate change on water quality constituents and implications for adaptive management.
(2013)The past few decades have seen, amongst other topical environmental issues, increased concerns regarding the imminent threat of global warming and the consequential impacts of climate change on environmental, social and ... -
Quantifying and benchmarking irrigation scheme performance with water balances and performance indicators.
(2007)South Africa is a water scarce country. As pressure on available water resources increases, irrigation, the largest consumer of water, has to find ways of improving water use efficiency. Benchmarking in the irrigation ... -
Quantifying hydrological fluxes of contributing hillslopes in the Weatherley catchment, N. E. Cape, South Africa.
(2009)Hillslope mechanisms and processes are a complex and dynamic set of interactions, but are nevertheless vital components of hydrology due to their critical interactions with surface and groundwater (Lorentz, 2001a). In ... -
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 ...
