An evaluation of priority and fractional methods of water allocation in the Sand River catchment, South Africa.
(2014)The development and apportionment of water resources is a critical issue, both globally and locally in South Africa. This is particularly true in the development and allocation among states sharing watercourse systems. ... -
An adaptive operational water resources management framework for the Crocodile River catchment, South Africa.
(2014)River catchments are complex STEEP (Social, Technological, Economic, Environmental, Political) systems requiring an integrated and adaptive approach to their water resources management with input from diverse stakeholders ... -
The effect of long-term fire frequencies on soil hydraulic properties in semi-arid savannas in Kruger National Park.
(2013)Soils are vital in supporting healthy and functioning ecosystems. Thus when soils are degraded, important ecosystem services are affected. In African savannas where fire is a key driver controlling ecosystem composition ... -
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 ... -
The effect of spatial resolution in remote sensing estimates of total evaporation in the uMgeni catchment.
(2014)The estimation of total evaporation plays a vital role in water resources monitoring and management, especially in water-limited environments. In South Africa, the increasing water demand, due to population growth and ... -
Spatial assessment of optimum and sub-optimum growing areas for selected biofuel feedstocks in South Africa.
(2014)Energy production using fossil-based fuels (coal, oil and natural gas) has environmental and health effects that have the potential to endanger human welfare. Escalating oil prices and the contribution of carbon dioxide ... -
The influence of scale and parent material on hillslope hydrological processes in Kruger National Park.
(2014)Semi-arid savannas are dynamic and complex systems controlled by fire, nutrient and water availability where water is the major driving force controlling the biological activity in these systems. Knowledge of hydrological ... -
Development of a connectivity index to assess aquatic macroinvertebrate species vulnerability to thermal change : a case study in KwaZulu-Natal Province.
(2015)Connectivity of river systems is a critical ecological component affecting not only the integrity of aquatic systems but also freshwater species’ habitat, community structure, migration and other life activities such as ... -
Hydrological connectivity in selected pristine catchments in the Kruger National Park.
(2014)The understanding of interactions between hydrological processes is essential, especially in water limited ecosystems in semi-arid environments. It is through this understanding that informed planning and management decisions ... -
An assessment of satellite derived total evaporation data as a data source to the ACRU hydrological model.
(2014)Hydrological models and tools are often used as decision support systems to inform water resources management. The successful application of these systems is largely dependent on the quality of data being incorporated into ... -
Impact of SOx and NOx deposition on the leaching behaviour of soils and water quality in the South African highveld.
(2014)Atmospheric emissions of sulphur and nitrogen oxides lead to the formation of acid rain, which, when deposited, can result in soil and water acidification. Cases of soil and water acidification have been reported in temperate ... -
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 ... -
Evaluating the effects of pre-packaging, packaging and varying storage environment treatments on the quality of avocados (Persea americana mill.)
(2013)Avocados are characterized as climacteric fruit and are vulnerable to rapid physiological deterioration. Maintaining avocado fruit quality requires proper integrated postharvest technologies. Thus, the primary aim of this ... -
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 ... -
A description, quantification and characterization of hillslope hydrological processes in the Weatherley catchment, Eastern Cape Province, South Africa.
(2013)Advances in hillslope hydrology have been numerous in the past two decades. However many of these advances have been highly site specific in nature, without identifying any means of linking processes across different ... -
Simulation modelling of sugarcane harvest-to-crush delays.
(1998)Long delays between harvesting and crushing of sugarcane lead to excessive deterioration in the quality of sugarcane. The aim of this project was to develop a computer based model of sugarcane harvesting and delivery ... -
The design, construction and testing of a mobile essential oil distillation unit.
(2005)Steam distillation is the most widely accepted process for the large scale production of volatile essential oils from herbaceous material and is also regarded as the standard practice throughout the flavour and fragrance ... -
Spatial and temporal variations of water and nutrient fluxes within a steep-sloped agricultural catchment.
(2012)A proper understanding of the spatial and temporal variations of runoff and nutrient fluxes are critical in understanding catchment hydrology. Runoff and nutrient fluxes may exhibit large variations both spatially and ... -
Deep row trenching of pit latrine and waste water treatment works sludge : water and nutrient fluxes in forest plantations.
(2012)The deep row trenching of ventilated improved pit-latrine (VIP) and waste water treatment works (WWTW) sludge is a unique alternative cost effective land application method that will prevent odour and health problems and ... -
An assessment of shallow water tables and the development of appropriate drainage design criteria for sugarcane in Pongola, South Africa.
(2012)South Africa, in common with all countries with arid or semi-arid climatic conditions, is facing the consequences of irrigation development without effective subsurface drainage. The quality of irrigation water is also ...
