A framework to improve irrigation design and operating strategies in the South African sugarcane industry.
(2009)The purpose of this study was to develop a framework to assess irrigation design and operating strategies. This objective was achieved successfully and the framework was applied to formulate guidelines to increase farm ... -
A simulation study of cane transport system improvements in the Sezela Mill area.
(2009)The South African sugar industry is of significant local and international importance and covers an area in excess of 450 000 hectares. This area yields approximately 21 million tons of sugarcane per annum which is transported ... -
Agroclimatic response mapping for sugarcane production in southern Africa.
(2008)As is the case in many other regions in the world, sugarcane production in southern Africa is affected by a wide range of climatic conditions, which can vary considerably from location to location and from year to year. ... -
An integrated sugarcane supply chain model : development and demonstration.
(2006)The South African sugar industry is a large industry which relies on expensive capital equipment to harvest, transport and process sugarcane. An average of 23 million tons of sugarcane are annually supplied to 14 mills ... -
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 ... -
An assessment of scale issues related to the configuration of the ACRU model for design flood estimation
(2010)There is a frequent need for estimates of design floods by hydrologists and engineers for the design of hydraulic structures. There are various techniques for estimating these design floods which are dependent largely on ... -
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 ... -
Balancing water for food and environment : hydrological determinants across scales in the Thukela River Basin.
(2008)In this study, geophysical measurements (Electrical Resistivity Tomography-ERT) and remote sensing techniques were applied in the Thukela river basin at various scales to complement the classical hydrometeorological ... -
Conceptualisations and applications of eco-hydrological indicators under conditions of climate change.
(2009)Anthropogenically-induced climate change has the potential to have serious implications on aquatic ecosystems and may ultimately affect the supply and quality of freshwater lakes and rivers throughout the world. As a class ... -
Definition of soil water dynamics by combining hydrometry and geophysics in a hillslope transect in the KNP.
(2006)The budgeting of water fluxes in the soil is an extremely complex problem, and is compounded by subsurface controls and environmental forces which modify the soil water dynamics. Of the controlling factors, the underlying ... -
The design and testing of soil pressure sensors for in-field agricultural and forestry traffic.
(2005)River stage or flow rates are required for the design and evaluation of hydraulic structures. Most river reaches are ungauged and a methodology is needed to estimate the stages, or rates of flow, at specific locations in ... -
Design of a brush cutter blade and its integration into a semi mechanized sugarcane harvesting system.
(2007)Sugarcane is an important crop for South Africa. It provides employment and valuable foreign -
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 ... -
Determining the capability of a vegetation cover to limit effluent leaching from a waste impoundment.
(2009)A final cover on a waste impoundment is the main physical barrier between the waste impoundment and the environment designed to protect against physical, chemical and biological factors isolating the waste from the atmospheric ... -
Developing a real time hydraulic model and a decision support tool for the operation of the Orange River.
(2002)This thesis describes the development of a decision support tool to be used in the operation of Vanderkloof Dam on the Orange River so that the supply of water to the lower Orange River can be optimised. The decision support ... -
The development and assessment of a prototype water accounting system for South Africa using the ACRU2000 and MIKE BASIN models..
(2010)South African water management areas could find themselves without enough water for its users due to new methods of performing water allocation as stipulated in the National Water Act of 1998. A water accounting system ... -
Development and assessment of an automatic short furrow irrigation system.
(2010)Automated short furrow irrigation (ASFI) is a prototype irrigation system that has the potential to be robust and relatively low-cost, with highly effective and efficient water use. ASFI has low energy requirements because ... -
The development and assessment of techniques for daily rainfall disaggregation in South Africa.
(2005)The temporal distribution of rainfall , viz. the distribution of rainfall intensity during a storm, is an important factor affecting the timing and magnitude of peak flow from a catchment and hence the flood-generating ... -
The development and evaluation of an operating rule framework for the ACRU agrohydrological modelling system.
(2001)Dams hold numerous benefits for society through their ability to store water on a long-term basis. However, it is well-known that there is a detrimental effect of dams on the rivers that they impound, and this has been ... -
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 ...
