192 Research Journal of Fisheries and Hydrobiology, 6(3): 192-210, 2011 ISSN 1816-9112 ORIGINAL ARTICLES The Probability Of Zagros Mountains Environmental Pollution Due To Seismic Response Of Bakhtiari Dam Zaniar Tokmechi Department of Civil Engineering, Mahabad Branch, Islamic Azad University, Mahabad, Iran. ABSTRACT The Bakhtiari Dam is a planned arch dam on the Bakhtiari River within the Zagros Mountains in Lorestan Province, Iran. At a planned height of 315 meters (1,033 ft), it will be the world's tallest dam once completed and withhold the largest reservoir in Iran. The Zagros Mountains are the largest mountain range in Iran and Iraq. With a total length of 1,500 km (932 mi), from northwestern Iran, and roughly correlating with Iran's western border, the Zagros range spans the whole length of the western and southwestern Iranian plateau and ends at the Straits of Hormuz. In this paper, the probability of environmental pollution due to heavy metals caused by Bakhtiari dam failure is studied. Finite Element and ZENGAR methods are used to analyze the probability of pollution at dam downstream. Different dam cross sections and various loading conditions are considered to study the effects of these factors on the seismic behavior of the dam. Results show that the effect of the highest cross section is not the most significant for heavy metals pollution at the dam down stream. Pollution coefficient due to stress along Y axis (Sy) is always the determinant pollution. While, in all sections Sx and Sy are the determinant parameter affecting downstream heavy metal pollution and normally are bigger than Sz. -

TECHNICAL NOTE GYPSUM DISSOLUTION EFFECTS ON THE PERFORMANCE OF A LARGE DAM M. Kiyani*, J. Sadrekarimi and B. Fakhri Department of Civil Engineering, University of Tabriz Postal Code 5166616471, Tabriz, Iran [email protected] – [email protected] – [email protected] *Corresponding Author (Received: March 2, 2007 – Accepted in Revised Form: January 30, 2008) Abstract Upper Gotvand dam is constructed on the Karun River located in the south west of Iran. In this paper, 2D and 3D models of the dam together with the foundation and abutments were constructed and several seepage analyses were carried out. Then the gypsum veins scattered throughout the foundation ground and also the seepage pattern were included in the models, hence the dissolution law of gypsum, was analyzed. It was disclosed that, the discharge fluxes obtained from 2D and 3D analyses are not similar and the discharge flux in 3D model is about 4 times the size of 2D model. Also, the 3D model localizes the phreatic surface some what higher than the 2D model does. This means that the 2D model estimates lower pore water pressure pattern in comparison with the 3D model. These may be attributed to the fact that with 2D model the lateral components of vectors of seepage velocity are ignored. In spite of the fact that the grout curtain is designed to be some 170 meters deep, however, complete dissolving of gypsum will severely increase the discharge flux through the foundation ground.

We are an international organisation that strives to promote the use of small hydro power (SHP) as a clean energy solution to meet the growing demand for energy in the world. The network supports over 380 organisations in more than 75 countries in their small hydro power related activities. This newsletter highlights some of IN-SHP’s recent and forthcoming activities. The headquarters of IN-SHP, the International Centre on Small Hydro Power (ICSHP), is one of UNIDO’s International Technology Centres. This March a meeting was held in Vienna between the centres for renewable energies, including the ICSHP and its regional sub-centres in Asia and Africa. The objective of the meeting was to share experiences and to strengthen cooperation between the centres. Supporting projects under the Clean Development Mechanism (CDM) is an Prof. Liu Heng important service offered by the ICSHP. Recently two CDM projects Director General, IN-SHP developed by the ICSHP in China were officially accredited. The centre has also been involved in a research on a green hydropower index system composed of hydrological parameters. This research has been going on since 2009 to assist the evaluation of impact of hydro power projects on river systems. In January the IN-SHP also hosted a visit from Zambia in the context of the ‘Lighting up Rural Africa’ project. -

In addition, ARQ is assisting with repair works and a new spillway at the 20 m high “My Own Dam” in Mpumalanga. UMTI DAM, OMAN ARQ will have its fi rst experience of hardfi ll in 2013 at the Umti Dam in central Oman, having generally been involved in high- and medium-paste content RCCs to date. Th e Wadi Umti project was recently awarded by the Ministry of Regional Municipalities and Water Resources to Omani contractors Premier International Projects (PIP), and ARQ is providing assistance in various forms to PIP in the planning and implementation of the proposed dam structure. Although the proposed fl ood alleviation and wadi-recharge dam is only 23 m in height, deep excavations, signifi cant founda- tion treatment, the requirement for permanent road access for Site for the proposed RCC/hardfi ll Umti Dam in central Oman upstream residents and no space for river diversion in the steep- sided valley imply that the intended 12-month construction programme is rather ambitious. -
Sediment Management in Hydropower Dam (Case Study – Dez Dam Project)
6 Sediment Management in Hydropower Dam (Case Study – Dez Dam Project) H. Samadi Boroujeni Shahrekord University, Iran 1. Introduction Hydropower reservoirs are loosing their capacity due to sedimentation processes, and are therefore seriously threatened in their performance. Without any mitigating measures the viability of many reservoirs in the worldwide is questionable, as the impacts and losses are not balanced by the profits. It is apparent that for mastering the reservoir sedimentation issues the use of strategies for controlling reservoir sedimentation becomes increasingly important because of sustainable development issues. Basic principles in sustainable development and use of reservoirs are: Human beings are at the center of concerns for sustainable development and use. Humans are entitled to a healthy and productive life in harmony with nature. Along with the right to develop and use reservoirs comes the responsibility to meet the needs of present and future generations. To achieve sustainable development and use of reservoirs and a higher quality of life for all people, we should gradually reduce and eliminate unsustainable patterns of development and use subject to social, environmental, and economic considerations. Reservoir sedimentation shortens the useful life of reservoirs. Systematic and thorough consideration of technical, social, environmental, and economic factors should be made to prolong the useful life of reservoirs. Approximately 1% of the storage volume of the world's reservoir is lost annually due to sediment deposition [Morris and Fan, 1998]. In some developing countries, where watershed management measures are not carried out effectively, reservoir storage is being lost at much larger rates. Although the reduction of sediment yield via a watershed management program is the best option for reducing the rate of reservoir sedimentation, flushing may be one of the most economic methods which offer recovering of lost storage without incurring the expenditure of dredging or other mechanical means of removing sediment. -
