Multipurpose Water Uses of Hydropower Reservoirs MULTIPURPOSE WATER USES OF HYDROPOWER RESERVOIRS 7 APRIL 2015 “SHARING THE WATER USES OF MULTIPURPOSE HYDROPOWER RESERVOIRS: THE SHARE CONCEPT” FINAL VERSION This paper presents the main deliverables of the EDF – WWC framework “multipurpose water uses of hydropower reservoirs”. Multipurpose hydropower reservoirs are designed and/or operated to provide services beyond electricity generation, such as water supply, flood and drought management, irrigation, navigation, fisheries, environmental services and recreational activities, etc. These reservoir purposes can conflict at times but are also often complementary: a major challenge with multi‑purpose reservoirs is sharing water amongst competing users. This framework provides: tools to avoid/minimize tensions among users, governance issues for all stages and financial/economical models to develop and operate such multipurpose reservoirs. The SHARE concept was developed as a solution of these challenges. It is based on international case studies to find guidance on particular issues of multipurpose water reservoirs.

  • Earthquakes, Dam Design and Tehri Project* by C.D
    Earthquakes, Dam Design And Tehri Project* by C.D. Thatte** DAMS AND THEIR DESIGN PHILOSOPHY ROLE PLAYED BY DAMS AND RESERVOIRS Dams have been built across rivers by mankind right from the dawn of civilisation for storing the river flow during rainy season and r~leasing it during the remaining part of year for either domestic use or for irrigation. Flood control has been another important function of these dams. While releasing water from the storages, hydroelectric energy is also generated. With the growth of population all these functions of dams and storages have assumed great significance and hence every civilisation has tried to keep pace with the needs ofthe society for food, energy, fibre and well being through this activity of water resources development. INPUTS FOR SAFE DESIGN Dams constitute perhaps the largest and the most complex of structures being built by civil engineers. Basic input of water is dependent on nature, so also the river course, its history, its underlying strata and its stability. Assessment of the variability of these natural phenomena and providing for it in the design of a dam, has been an important challenge for the dam builders. The dams are built to last from 100 to 300 years depending upon merits of each case. During their service life, they are designed to withstand all the possible destabilising forces with a certain factor of safety which has been an indicator of a factor of ignorance or lack of knowledge of various response processes of materials used in construction, the stresses caused, the strains experienced and finally the failure mechanism.

  • Hydrological Impact of Deforestation in the Central Himalaya
    Hydrology ofMountainous^4reoi (Proceedings of the Strbské Pleso Workshop, Czechoslovakia, June 1988). IAHS Publ. no. 190, 1990. Hydrological impact of deforestation in the central Himalaya M. J. HAIGH Geography Unit, Oxford Polytechnic Headington, Oxford, England J. S. RAWAT, H. S. BISHT Department of Geography, Kumaun University Almora, U.P., India ABSTRACT Deforestation is the most serious environmental problem in Uttarakhand, home of the Chipko Movement, the Third World's leading nongovernmental organization (NGO) dedicated to forest con­ servation. This group exists because of the rural people's concern for the loss of forests and their personal experience of the envi­ ronmental consequences. Despite this, it has become fashionable for scientists from some international organizations to argue there is little evidence for recent deforestation, desertification, acce­ lerated erosion and increased flooding in the region. This paper tries to set the record straight. It summarizes results collected by field scientists in Uttarakhand. These data reinforce the popu­ lar view that deforestation and environmental decline are very ser­ ious problems. Preliminary results from the Kumaun University/Ox­ ford Polytechnic instrumented catchment study are appended. This catchment is set in dense Chir (Pinus roxburghii) forest on a steep slope over mica schist in a protected wildlife sanctuary on the ur­ ban fringe at Almora, U.P. The results demonstrate a pattern of sediment flushing associated with the rising flows of the Monsoon. INTRODUCTION Deforestation is the most serious environmental problem in Uttar­ akhand, the Himalaya of Uttar Pradesh, India (Fig. 1). This tract, which covers nearly 52 thousand km2 on the western borders of Nepal, is home of the "Chipko" Movement, the Third World's leading NGO devoted to forest conservation (Haigh, 1988a).

  • Hydro 4 Water Storage
    TERM OF REFERENCE 3: STATE-WIDE WATER STORAGE MANAGEMENT The causes of the floods which were active in Tasmania over the period 4-7 June 2016 including cloud-seeding, State-wide water storage management and debris management. 1 CONTEXT 1.1 Cause of the Floods (a) It is clear that the flooding that affected northern Tasmania (including the Mersey, Forth, Ouse and South Esk rivers) during the relevant period was directly caused by “a persistent and very moist north-easterly airstream” which resulted in “daily [rainfall] totals [that were] unprecedented for any month across several locations in the northern half of Tasmania”, in some cases in excess of 200mm.1 (b) This paper addresses Hydro Tasmania’s water storage management prior to and during the floods. 1.2 Overview (a) In 2014, Tasmania celebrated 100 years of hydro industrialisation and the role it played in the development of Tasmania. Hydro Tasmania believes that understanding the design and purpose of the hydropower infrastructure that was developed to bring electricity and investment to the state is an important starting point to provide context for our submission. The Tasmanian hydropower system design and operation is highly complex and is generally not well understood in the community. We understand that key stakeholder groups are seeking to better understand the role that hydropower operations may have in controlling or contributing to flood events in Tasmania. (b) The hydropower infrastructure in Tasmania was designed and installed for the primary purpose of generating hydro-electricity. Flood mitigation was not a primary objective in the design of Hydro Tasmania’s dams when the schemes were developed, and any flood mitigation benefit is a by-product of their hydro- generation operation.
