Çamlıdere Dam supplies significant portion of the potable water demand of the City of Ankara. Consequently, it is very important that the pipelines extending over 60 km between the dam and the treatment plant at İvedik operate continuously. At present, two composite parallel lines are in operation and construction of a third line is considered for the future. It is the aim of this study to investigate the water hammer problems to be expected under various scenarios and also suggest the safe operation conditions for the system. Water hammer analyses of the pipeline are carried out by computer software named HAMMER. This software employs the Method of Characteristics (MoC) which is a widely used mathematical procedure in solving the non-linear differential equations caused by unsteady flow. Within this theses work, existing tunnels, prestressed concrete and steel pipes, third steel pipeline which is planned to be constructed in the future and existing, and future-planned valves are modeled and calibration of the model is implemented. A plenty of scenarios and valve closure principles are constituted in order to specify steady-state conditions and additional water hammer pressures generated by several excitations through the pipeline. Results of these scenarios are compared with previous works conducted on the pipeline system and the most unfavorable ones among those are determined. Then, appropriate closure durations are identified and suggested for pipe fracture safety valves and the flow control valves at İvedik in order not to cause excessive pressures in the system.

Hydraulic characteristics of tyrolean weirs having steel racks and circular-perforated entry Şahiner, Halit; Göğüş, Mustafa; Department of Civil Engineering (2012) Tyrolean type water-intake structures are commonly used on mountain rivers to supply water to hydropower stations. The amount of water to be diverted from the main channel is the major concern in these kind of structures and should not be less than the design discharge. In this study a physical model of a Tyrolean type water-intake structure was built at the laboratory and the diverted flow from the main channel through the intake structure having steel racks and perforated plates of different types were me...
Investigation of waterhammer problems in the penstocks of small hydropower plants Çalamak, Melih; Bozkuş, Zafer; Department of Civil Engineering (2010) Waterhammer is an unsteady hydraulic problem which is commonly found in closed conduits of hydropower plants, water distribution networks and liquid pipeline systems. Due to either a malfunction of the system or inadequate operation conditions, pipeline may collapse or burst erratically resulting in substantial damages, and human losses in some cases. In this thesis, time dependent flow situations in the penstocks of small hydropower plants are investigated. A software, HAMMER, that utilizes method of chara...
Rule curves for operating single- and multi-reservoir hydropower plants Ak, Mümtaz; Kentel Erdoğan, Elçin; Savaşaneril Tüfekci, Seçil; Department of Civil Engineering (2017) Hydropower has the largest share in the energy budget of Turkey among renewable energy sources. Thus, planning and operation of hydropower plants (HPPs) are critical for the country. Currently, sustainable use and development of water resources to maximize possible benefits are the two big challenges to be overcome and efficient use of hydropower forms a significant component of this. The Çoruh Basin has an economically high hydropower potential, as such there are many HPPs that are in operation, under cons...
Quantitative flood risk assessment with application in Turkey Keskin, Fatih; Şorman, Ali Ünal; Department of Geodetic and Geographical Information Technologies (2012) Floods can result in enormous causalities and huge economic losses in urban and rural regions. In recent years, while assessing the damage, risk analysis and assessment has become an important tool in addressing uncertainty in flood hazards. The lack of knowledge about the water extend, water depth, water velocity and potential damage in case of flood increase the vulnerability of the people to disasters in the flood region. Especially this information is valuable for city planners and decision makers. In c...
Scenario Planning for Water Resources A Saudi Arabian Case Study Dejong, Remy Lucıen; Yazıcıgil, Hasan; Allayla, Rashıd Ibrahım (1989-01-01) Uncommonly rapid development of the oil-rich Eastern Province of Saudi Arabia has led to heavy stresses on the local groundwater resources and there has arisen concern for the adequacy of supply to sustain future growth. Whereas oil is the only significant export commodity, the demand for it has an important and immediate impact on water exploitation activities. In this article four development scenarios are considered, each resulting in a specific water abstraction pattern. The hydrologic consequences of e...
