Groundwater Recharge Assessment in the Upper Limpopo River Basin: a Case Study in Ramotswa Dolomitic Aquifer
Groundwater Recharge Assessment in the Upper Limpopo River Basin: A Case Study in Ramotswa Dolomitic Aquifer Submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, In partial fulfilment of the requirements for the degree of Master of Science in Hydrogeology Submitted by: Simamkele Siyambonga Baqa Student number: 1098513 Supervisors: Dr. Karen Villholth (IWMI) Prof. Tamiru Abiye (Wits) July 2017 in Johannesburg Groundwater Recharge Assessment in the upper Limpopo River Basin: A case study in Ramotswa Dolomitic Aquifer Declaration I Simamkele Siyambonga Baqa declare that Groundwater Recharge Assessment in the upper Limpopo River Basin with a case study in Ramotswa Dolomitic Aquifer is my own investigation and covers no section copied in whole or in part from any source unless it is clearly acknowledged in quotation marks and with detailed, complete and precise referencing. Further, the report has not been submitted before for any degree or examination at any university. …………………………………….. (Signature) ………………… (Date) I Abstract Hydrogeological research was undertaken in the transboundary Ramotswa dolomitic aquifer to provide understanding and quantification of the processes governing recharge mechanism and rates, in order to promote efficient and sustainable groundwater resource utilization and development, as well as to improve the Ramotswa transboundary aquifer management. Hydrochemical and tracer approaches were utilized to evaluate the processes governing the recharge mechanism while the chloride mass balance approach was further applied to assess groundwater recharge rates. Results indicated that all groundwater samples contained detectable amounts of tritium highlighting the renewability of the transboundary Ramotswa aquifer resources. Two distinct water types were characterised: sub-modern waters approximately recharge prior to the 1950s and a mixture of modern and sub-modern waters of recently recharge rainfall indicative of active recharge in the area through intensive rainfall. -
River Health Programme in the North West Province
RIVER HEALTH PROGRAMME IN THE NORTH WEST PROVINCE What is the River Health Programme? ‚ It is a national programme co-ordinated by DWAF, DEAT, WRC designed to monitor the condition of rivers in South Africa using standardised bio- monitoring techniques. What is biomonitoring? ‚ Use of living organisms as biological indicators of ecosystem or environmental “health”. ‚ Animals and plants provide a long-term integrated reflection of water quality and quantity, habitat quality and other environmental conditions What is being monitored in the River Health Programme? Indices of Ecosystem health ‚ Fish (Fish Community Integrity Index) ‚ Aquatic Invertebrates (South African Scoring System SASS4) ‚ Aquatic Habitats (Integrated Habitat Assessment System IHAS) ‚ Plants (Riparian Vegetation Index RVI) ‚ Water flow (Hydrological Index) ‚ Water quality (Dissolved Oxygen, pH, Conductivity, Temperature) ‚ River channel condition (Geomorphological Index) Advantages of biomonitoring ‚ Detects changes in water quality e.g pollution from mining, industry and agriculture ‚ Detects effects of changes in water flow e.g dams, bridges and forestry ‚ Standardized method of comparison of water quality ‚ Easy to use practical means of assessing water quality ‚ Relatively cheap and quick ‚ Can detect water quality changes which may be missed by chemical sampling ‚ Non-destructive - animals returned live to water. Disadvantages to biomonitoring ‚ A fair amount of training is required ‚ Can be open to subjective interpretation ‚ Does not provide an exact figures of water quality parameters ‚ Cannot pinpoint the exact cause of water quality problems ‚ Has no legal standing North West Rivers identified for River Health Programme ‚ Groot Marico River ‚ Hex River near Rustenburg ‚ Elands River near Rustenburg ‚ Crocodile River downstream of Hartebeespoort Dam ‚ Mooi River near Potchefstroom ‚ Schoonspruit near Ventersdorp to Orkney ‚ Harts River from Lichtenburg to Spitzkop Dam ‚ the section of the Vaal River forming the boundary between the Free State and the North West. -
Overview of Experiences in the Limpopo River Basin
intersectorai Management of River Basins Overview of Experiences in the Limpopo River Basin Thomas Schild Team Leader, German Agency for Technical Co-operation (GTZ), Windhoek, Namibia Abstract The paper presents a summary of the findings of a German mission to four countries of Southern Africa, in which many people at different levels were asked to give their views about water issues in two trans-national river basins, the Limpopo and the Orange-Senqu. The principal common factors in people's responses are identified. Various sources and types of inequity are described. In conclusion, it is found that external assistance could be especially useful in areas of information and communication, and in organisational development for river-basin management. 1. Context A mission by a project appraisal team of the German Agency for Technical Co operation (GTZ) was carried out in September 2000, for the support of regional water management in the SADC (Southern African Development Community) region. The team talked to stakeholders of the Limpopo and the Orange-Senqu river basins. The mission had the following major tasks; Map the scene; Capture the expectations and issues of concern of the stakeholders with regard to the establishment of river basin commissions; Identify possible areas for technical co-operation; Make preparations for the planning workshop. 2. Procedures Between 14 and 29 September 2000, the group visited Zimbabwe, Mozambique, Botswana and South Africa and held discussions with relevant government institutions, parastatals and donor organisations involved in water resources management of the Limpopo and, where applicable, of the Orange/Senqu. Other resource persons, such as representatives of water users' organisations, researchers, non-governmental organisations (NGOs) and consultants were met. -
The Lion and the Springbok
The Lion and the Springbok The Lion and the Springbok presents a unique account of the dynamics and divergences of the ‘uneasy special relationship’ between Britain and South Africa. From the bruising experience of the South African War (1899–1902) to South Africa’s withdrawal from the Commonwealth in 1961, the authors chart this relationship in all its political, economic, cultural, and geostrategic aspects. All the major disputes are discussed, including the struggle for the High Commission Territories, the crisis over Seretse Khama’s marriage, and the transfer of the Simon’s Town naval base. These issues trace, for the most part, a continuing deterioration in relations, as Afrikaner nationalist identity hardened and South African politics slid into the extremes of apartheid. The perceptions each side had of the other after 1948 are examined through representations in the media, and an epilogue considers the reasons for the return of the ‘new South Africa’ to the Commonwealth in 1994. ronald hyam is Emeritus Reader in British Imperial History, University of Cambridge, and a Fellow and former President of Magdalene College. peter henshaw is a Research Professor in History at the University of Western Ontario.

Box Cy617 Causeway, Harare, Zimbabwe 2Department of Civil Engineering, University of Zimbabwe, P.O. Box MP167, Mt Pleasant, Harare, Zimbabwe 3WaterNet Secretariat, P.O. Box MP600, Mount Pleasant, Harare, Zimbabwe Correspondence: Colleta Tundu ([email protected]) Received: 7 June 2017 – Accepted: 10 October 2017 – Published: 16 April 2018 Abstract. Sediment delivery into water sources and bodies results in the reduction of water quantity and quality, increasing costs of water purification whilst reducing the available water for various other uses. The paper gives an analysis of sedimentation in one of Zimbabwe’s seven rivers, the Mazowe Catchment, and its impact on water quality. The Revised Universal Soil Loss Equation (RUSLE) model was used to compute soil lost from the catchment as a result of soil erosion. The model was used in conjunction with GIS remotely sensed data and limited ground observations. The estimated annual soil loss in the catchment indicates soil loss ranging from 0 to 65 t ha yr−1. Bathymetric survey at Chimhanda Dam showed that the capacity of the dam had reduced by 39 % as a result of sedimentation and the annual sediment deposition into Chimhanda Dam was estimated to be 330 t with a specific yield of 226 t km−2 yr−1. -
