  • Sustaining Water Supplies While Responding to Operational Requirements at De Beers Venetia Mine
    SUSTAINING WATER SUPPLIES WHILE RESPONDING TO OPERATIONAL REQUIREMENTS AT DE BEERS VENETIA MINE Gary Brown1 and Philip Erasmus2 1Golder Africa Associates, PO Box 6001, Halfway House, 1685. 2De Beers Venetia Mine, PO Box 668, Musina, 0900. ABSTRACT The intrepid novelist Rudyard Kipling’s portrayal of the Limpopo River as “the great, grey-green, greasy Limpopo River, all set about with fever trees …” does not reflect the real challenges De Beers Venetia Mine faces in abstracting raw water for their open cast kimberlite operation, located in the remote arid northern extremities of South Africa, approximately 80 km west of Musina and some 500 km north of Johannesburg, with the area presenting a mean annual precipitation value of 350 mm and annual evaporation rates in the order of 2 500 mm. Construction of Venetia Mine began in 1990, was officially opened in August 1992 and had reached full output in 1993. Venetia Mine is South Africa’s largest producer of diamonds. Production statistics for 2002 reflect total tonnages mined of 24,3 million of which 4,71 million tons of ore was processed and 5,08 million carats recovered. Despite the large catchment and many tributaries, the largest being the Shashe River, feeding the Limpopo River, the river is usually dry for most of the year. Ninety percent of the river’s runoff occurs from December to April. The Mine’s commitment to practising sound environmental management principles is reflected in its proud list of environmental orientated achievements. Despite these challenging conditions and strict statutory and self imposed restrictions to water abstraction for supply to the Mine, the Mine has since commissioning and with increased production not exceeded the overall water abstraction permit volumes and has demonstrated acute ability in integrating the supply of water for its operations between surface flow conditions in the Limpopo River and the ground water source within the Greefswald and Schroda aquifer.

  • Evaluation of Flood Risks Using Flood Frequency Models: a Case Study of Luvuvhu River Catchment in Limpopo Province, South Africa
    This paper is part of the Proceedings of the 5th International Conference on Flood Risk Management and Response (FRIAR 2016) www.witconferences.com Evaluation of flood risks using flood frequency models: a case study of Luvuvhu River Catchment in Limpopo Province, South Africa L. R. Singo1,2, P. M. Kundu2, F. I. Mathivha2 & J. O. Odiyo2 1Process Technology Department, Rand Water, South Africa 2Department of Hydrology and Water Resources, University of Venda, South Africa Abstract The Luvuvhu River Catchment has experienced floods of varying magnitudes resulting from heavy rainfall associated with the Intertropical Convergence Zone and cyclones. Human activities in the catchment have aggravated risks of flooding. Risks of flooding have been experienced in the past, with the major ones occurring during sporadic rainfall events. This study aims to evaluate flood risks through rainfall distribution characteristics in the catchment using flood frequency models. Statistical analyses that include Gumbel and Log- Pearson Type III distributions were selected to perform flood frequency analysis. Peak flood magnitudes for the 2, 5, 10, 25, 50, 100 and 200-year recurrence intervals were estimated using the two distributions. In peri-urban areas such as the Luvuvhu River Catchment, design life of structures for low risks (10-year return periods) and medium risks (50-year return periods) catchments are important to manage risks. The results showed a general increase in the frequency of extreme events, accompanied by floods of higher magnitude. Design life of structures for low risks and medium risks catchments showed magnitudes in the range of 453.03 mm to 1495.48 mm for Log-Pearson Type III and 454.39 mm to 1370.16 mm for Gumbel’s.

  • Geological Inventory of the Maremani Nature Reserve
    Geological Inventory Of The Maremani Nature Reserve Professor Jay Barton Department of Geology, Rand Afrikaans University (RAU) P.O. Box 524, Auckland Park 2006, South Africa Telephone: 27-11-489-2304 FAX: 27-11-489-2309 E-mail: [email protected] Introduction The Maremani Nature Reserve is presently being established and this document is intended as a summary of aspects of the geology within the boundaries of the Reserve. I have taken the liberty also to express my opinions with regard to possible roles that the Reserve might fulfill with regard to promoting geological awareness, education and research. The geology of the area covered by the Reserve was mapped in 1976 by Gunther Brandl and W. O. Willoughby of the Geological Survey of South Africa (presently the Council For Geo- science) at a scale of 1:50 000 for compilation at a scale of 1:250 000 (Brandl, 1981). The western portion to 30o 15’ east was previously mapped at a scale of 1:10 000 for compilation at scales of 1:50 000 and 1:125 000 by P. G. Söhnge (1946; Söhnge et al., 1948). Also locally within the western portion of the Reserve, maps at the scale of 1:5 000 were compiled by Messina Transvaal Development Corporation on farms and prospects investigated by the staff of the Messina Copper Mine. These maps are presently archived with me at RAU. Peter Horrocks wrote a PhD thesis on the geology of part of the western portion of what is now the Reserve (Horrocks, 1981). Charles Guerin in the late 1970’s worked on an unfin- ished MSc thesis on the calc-silicate rocks exposed in an area south of that studied by Peter Horrocks, some of which occur within the Reserve.

  • Geology and Geochronology of the Nyl River Floodplain Sediments, Limpopo Province, South Africa
    Geology and geochronology of the Nyl River floodplain sediments, Limpopo Province, South Africa Debra Colarossi A Dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the Degree of Master of Science in Geology. Johannesburg 2013 Declaration I declare that this dissertation is my own, unaided work. It is being submitted for the Degree of Master of Science in the University of the Witwatersrand, Johannesburg. It has not been submitted before for any degree or examination in any other University. Signed: ______________________________ Date: ______________________________ ~ ii ~ Abstract The Nyl River floodplain, located in the Limpopo Province, is one of the few active sedimentary basins that exist within the South African interior, providing a unique opportunity to study the effect of climate change on fluvial systems. Progradation of tributary fans into the Nyl/Mogalakwena River has raised the surface by 30 m and forced the course of the river westwards towards the Waterberg. Periods of progradation deposited thick sequences of coarse-grained sediments with sand- to gravel-sized mean grain sizes and coarsely-skewed populations in the distal reaches of the tributary fans. These periods were interspersed with periods of relative non-deposition, when active sedimentation on the fan ceased and shallow lakes (or vleis) developed in the trunk river, resulting in deposition of fine-grained, organic-rich, floodplain sediment layers with silt-sized mean grain sizes and finely-skewed distributions in the extreme outer reaches of the tributary fan. The alternating progradational sequences and non-deposition events produced interlayered floodplain and fan deposits in the furthest reaches of the tributary fans along the banks of the Nyl/Mogalakwena River.

  • Limpopo Water Management Area
    LIMPOPO WATER MANAGEMENT AREA WATER RESOURCES SITUATION ASSESSMENT MAIN REPORT OVERVIEW The water resources of South Africa are vital to the health and prosperity of its people, the sustenance of its natural heritage and to its economic development. Water is a national resource that belongs to all the people who should therefore have equal access to it, and although the resource is renewable, it is finite and distributed unevenly both spatially and temporally. The water also occurs in many forms that are all part of a unitary and inter-dependent cycle. The National Government has overall responsibility for and authority over the nation’s water resources and their use, including the equitable allocation of water for beneficial and sustainable use, the redistribution of water and international water matters. The protection of the quality of water resources is also necessary to ensure sustainability of the nation’s water resources in the interests of all water users. This requires integrated management of all aspects of water resources and, where appropriate, the delegation of management functions to a regional or catchment level where all persons can have representative participation. This report is based on a desktop or reconnaissance level assessment of the available water resources and quality and also patterns of water requirements that existed during 1995 in the Limpopo Water Management Area, which occupies a portion of the Northern Province. The report does not address the water requirements beyond 1995 but does provide estimates of the utilisable potential of the water resources after so-called full development of these resources, as this can be envisaged at present.
