In Turkey with increasing energy demand by industrialization and urbanization, hydropower seemed to be the most environmental friendly and sustainable solution for the problem. However, hydropower has also environmental effects especially when hydropower projects are numerous on a single river, and they use almost entire water in the river. Environmental flow as a new term became popular in media with increased density of small hydropower projects in Turkey. It is the required flow in the part of diversion for Run-off River type of hydropower plant in order to protect health of the river; in other words, to balance components of the river, including physico-chemical quality standards, surface and groundwater, geomorphological dynamics, social, economic, cultural and landscape values. In this study, an analysis utilizing hydrological (desktop) environmental flow assessment methods is prepared for Turkey, focusing on the Pazarsuyu Basin as a case study, and the results are compared with the applications done by the Governmental Institutions. Moreover, insufficient applications with regard to environmental flow assessment are given and reasons for public concerns are pointed out due to small hydropower development in Turkey.

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...
Investigation Of Waterhammer Problems In Çamlidere Dam - İvedik Water Treatment Plant Pipeline At Various Hydraulic Conditions Sakabaş, Emre; Bozkuş, Zafer; Department of Civil Engineering (2012) 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 condit...
Contamination risk assessment for groundwater of the Kucuk Menderes River basin, Izmir, Turkey Pusatli, OT; Camur, MZ; Yazıcıgil, Hasan (2000-04-01) A new water management plan is needed for the Kucuk Menderes River basin in Turkey, due to increasing water demand and decreasing quality of the groundwater. Vulnerability, quality and risk assessments were performed using a hybrid model containing both hydrogeological and hydrochemical parameters for managing irrigation waters in the basin. The relative contamination (quality) distribution of groundwater at present was established using an irrigation water quality index. The distribution shows the contamin...
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...
Sustainable development of Turkey: Deployment of geothermal resources for carbon capture, utilization, and storage Kirli, Mustafa Safa; Fahrioglu, Murat (Informa UK Limited, 2019-07-18) As a developing country, Turkey's sustainable development objectives converge on robust and sustainable economic development. The increase in its energy and electricity demand is attributed to the growth of population, urbanization, and industrialization parallel to economic and social growth. Instead of fulfilling the obligation to protect the environment arising from international agreements and achieving desired sustainable development, the dependency on imported fossil fuel in electrical energy producti...
