    GEOTHERMAL RESOURCE INDICATIONS OF THE GEOLOGIC DEVELOPMENT AND HYDROTHERMAL ACTIVITIES OF D.R.C. Getahun Demissie Addis Abeba, Ethiopia, [email protected] ABSTRACT Published sources report the occurrence of more than 135 thermal springs in D.R.C. All occur in the eastern part of the country, in association with the Western rift and the associated rifted and faulted terrains lying to its west. Limited information was available on the characteristics of the thermal features and the natural conditions under which they occur. Literature study of the regional distribution of these features and of the few relatively better known thermal spring areas, coupled with the evaluation of the gross geologic conditions yielded encouraging results. The occurrence of the anomalously large number of thermal springs is attributed to the prevalence of abnormally high temperature conditions in the upper crust induced by a particularly high standing region of anomalously hot asthenosphere. Among the 29 thermal springs the locations of which could be determined, eight higher temperature features which occur in six geologic environments were found to warrant further investigation. The thermal springs occur in all geologic terrains. Thermal fluid ascent from depth is generally influenced by faulting while its emergence at the surface is controlled by the near-surface hydrology. These factors allow the adoption of simple hydrothermal fluid circulation models which can guide exploration. Field observations and thermal water sampling for chemical analyses are recommended for acquiring the data which will allow the selection of the most promising prospects for detailed, integrated multidisciplinary exploration. An order of priorities is suggested based on economic and technical criteria.

  • Anatomy of the Nile Following the Twists and Turns of the World's Longest River
    VideoMedia Spotlight Anatomy of the Nile Following the twists and turns of the world's longest river For the complete video with media resources, visit: http://education.nationalgeographic.org/media/anatomy-nile/ Funder The Nile River has provided fertile land, transportation, food, and freshwater to Egypt for more than 5,000 years. Today, 95% of Egypt’s population continues to live along its banks. Where does the Nile begin? Where does it end? Watch this video, from Nat Geo WILD’s “Destination Wild” series, to find out. For an even deeper look at the Nile, use our vocabulary list and explore our “geo-tour” of the Nile to understand the geography of the river and answer the questions in the Questions tab. Questions Where is the source, or headwaters, of the Nile River? The streams of Rwanda’s Nyungwe Forest are probably the most remote sources of the Nile. The snow-capped peaks of the Rwenzori Mountains are another one of the remote sources of the Nile. The Rwenzori Mountains, sometimes nicknamed the “Mountains of the Moon,” straddle the border between the Democratic Republic of the Congo and Uganda. Many geographers also consider Lake Victoria, the largest lake in Africa, to be a source of the Nile. The most significant outflow from Lake Victoria, winding northward through Uganda, is called the “Victoria Nile.” Can you find a waterfall on the Nile River? As it twists more than 6,500 kilometers (4,200 miles) through Africa, the Nile has dozens of small and large waterfalls. The most significant waterfall on the Nile is probably Murchison Falls, Uganda.

  • Assessing the Bujagali Hydropower Project in Uganda
    Modern Approaches in Oceanography and Petrochemical Sciences DOI: 10.32474/MAOPS.2019.02.000141 ISSN: 2637-6652 Research Article Assessing the Bujagali Hydropower Project in Uganda George Kimbowa1 and Khaldoon A Mourad2* 1Busitema University, Uganda 2Center for Middle Eastern Studies, Lund, Sweden *Corresponding author: Khaldoon A Mourad, Center for Middle Eastern Studies, Lund, Sweden Received: January 21, 2019 Published: January 29, 2019 Abstract The development of great dams and hydropower plants increases power supply and access. However, the process is considered a threat to livelihoods, ecosystem and biodiversity because in most cases it brings about human displacement and natural resources degradation. This paper seeks to assess the development of the Bujagali Hydropower Plant in Uganda (BHP) and its compliance with IWRM principles based on water knowledges, societal values, and inter-disciplinary approach. The paper develops a set of strategic interventions for the dam and the BHP based on SWOT analysis, XLRM framework, Multi-sectoral and interdisciplinary development approach, and sustainable management. These measures are deemed socially and ecologically acceptable by all stakeholders including the cultural and historical institutions, societal actor groups, including mega-hydraulic bureaucracies, the private sectors and national politicians. The results show that project developers should always carry out Environment and Social Impact Assessments (ESIA); develop timely ‘Resettlement Action Plan’; carry out informed consultation and participation; promote transparency; and communicate project’s risks, potential impacts and probable mitigation actions to attain sustainability. The paper proposes some policy interventions to be implemented along the project’s lifetime. Furthermore, it presents a sustainable development plan for such projects based on the IWRM principles.

  • Bujagali Final Report
    INDEPENDENT REVIEW PANEL COMPLIANCE REVIEW REPORT ON THE BUJAGALI HYDROPOWER AND INTERCONNECTION PROJECTS June 20, 2008 1 ACKNOWLEDGEMENTS The IRM Compliance Review Panel could not have undertaken and completed this report without the generous assistance of many people in Uganda and at the African Development Bank. It wishes to express its appreciation to all of them for their cooperation and support during the compliance review of the Bujagali Hydropower and Interconnection projects. The Panel thanks the Requesters and the many individuals from civil society and the communities that it met in the Project areas and in Kampala for their assistance. It also appreciates the willingness of the representatives of the Government of Uganda and the projects’ sponsors to meet with the Panel and provide it with information during its visit to Uganda. The Panel acknowledges all the help provided by the Resident Representative of the African Development Bank in Uganda and his staff and the willing cooperation it has received from the Bank’s Management and staff in Tunis. The Panel appreciates the generous cooperation of the World Bank Inspection Panel which conducted its own review of the “UGANDA: Private Power Generation Project”. The Compliance Review Panel and the World Bank Inspection Panel coordinated their field investigations of the Bujagali projects and shared consultants and technical information during this investigation in order to enhance the efficiency and cost effectiveness of each of their investigations. While this collaboration between the Panel and the World Bank Inspection Panel worked to the mutual benefit of both parties, each Panel focused its compliance review on its own Bank’s policies and procedures and each Panel has made its own independent judgments about the compliance of its Management and staff with its Bank’s policies and procedures.

  • Kingfisher Oil Development Surface Water

O. Box 22255 Kampala, Uganda READY VOLUME 4, STUDY 2 4, STUDY VOLUME – PRINT FINAL Report Number: 1776816‐321512‐13 REPORT Distribution: 1 x electronic copy CNOOC Uganda Limited 1 x electronic copy NEMA 1 x electronic copy Eco & Partner 1 x electronic copy Golder SURFACE WATER SPECIALIST REPORT EXECUTIVE SUMMARY This report presents hydrology baseline information and an impact assessment of surface water hydrology affected by the Project. An understanding of surface water hydrological conditions prior to mine oil and gas development is essential to assess changes in water availability that could affect local users. Changes in hydrology can also affect water quality and other resources such as fish habitat, vegetation and wildlife. Hydrological data is further required to design mine oil and gas facilities (e.g. culverts, channels and storage ponds). The regional climate in the area is described as tropical with a distinct wet and dry season. Rainfall over the study area catchment varies between 700 mm and 1 400 mm/ annum. Results of Global Climate Change models indicate that Uganda is likely to experience more extreme periods of intense rainfall and drought, while the rainfall seasons become more erratic and/or infrequent. The project site is located within the Kingfisher catchment and drains westwards into the south eastern embankments of Lake Albert. Kingfisher catchment is associated with a very high western rift escarpment that drains into Lake Albert via several scattered streams and wetlands flowing westwards.
