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 ... -
An adaptation of the SCS-ACRU hydrograph generating technique for application in Eritrea.
(2004)Many techniques have been developed over the years in first world countries for the estimation of flood hydrographs from small catchments for application in design, management and operations of water related issues. However, ... -
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 ... -
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 analysis of baseflow recession in the Republic of South Africa.
(1997)Demands on the water resources of South Africa are ever increasing owing to population growth and increased development of urban, peri-urban and rural communities. Problems in terms of water quantity and quality are ... -
Approaches to modelling catchment-scale forest hydrology.
(2002)South African commercial plantations occupy an estimated 1.5 million hectares of the country and as the demands for timber products increase, this area is expected to increase. However, further expansion is limited, not ... -
Assessing the performance of regional flood frequency analysis methods in South Africa.
(2015)In engineering and flood hydrology, the estimation of a design flood refers to procedures whereby the magnitude of a flood is associated with a level of risk at a given site (Pegram and Parak, 2004). The use of a Regional ... -
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 ... -
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 ... -
Assessment of satellite derived rainfall and its use in the ACRU hydrological model.
(2017)Many parts of southern Africa are considered water scarce regions. Therefore, sound management and decision making is important to achieve maximum usage with sustainability of the precious resource. Hydrological models are ... -
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 ... -
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 ... -
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 ... -
An assessment of the water use of indigenous and introduced tree SPP. and varying land uses around Vasi Pan, Maputaland, KwaZulu-Natal.
(2017)Abstract available in PDF file. -
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 ... -
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 ... -
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 ...
