SEDIMENTATION MANAGEMENT OF THE PATRIND HYDRO POWER PROJECT USING OHDS TECHNIQUE Woncheol. PARK Vice President, K-water Kiyong. AN Senior Manager of Overseas Business Division, K-water REPUBLIC OF KOREA 1. INTRODUCTION Fossil resource depletion and climate change have raised the interest of renewable energy around the world. Among them, the development of hydropower is considered to be an effective way to prepare for electricity shortages. In the case of Pakistan, the government has already set up the "Policy for Power Generation Projects” (2002) to encourage private participation in the electricity market, in which 16 hydroelectric projects have been proposed as long- term plans. Among them, the Patrind Hydro Power Project has been developed by SHPL and is owned by K-water(Main sponsor). In general, the development and operation of hydropower generation facilities are greatly influenced by hydrological and topographical conditions. In particular, sedimentation in the upstream of a dam causes reservoir volume reductions and generator abrasions. Therefore, a proper management technique for sedimentation is needed for hydropower plant projects. The area where the Patrind project is located is highly influenced by sedimentation due to the Himalayas. Therefore, it was necessary to apply a sedimentation management method considering topographic and geological conditions and trap efficiency. 2. PROJECT OUTLINE AND SEDEMENT MANAGEMENT GOALS 2.1. PROJECT OUTLINE The Patrind project is located in the city of Muzaffarabad and is about 120km northeast of Islamabad, which is capital of Pakistan. As it is a run-of-river type hydropower plant, water is taken from the Kunhar River and then generated by the 534
