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 case of new settlement area selection, correct decision can be taken by the help of this information. This type of information can be taken from hydraulic models as 1D or 2D. On the other hand, two dimensional (2D) hydraulic modeling becomes a need with increasing trends of very high speed computers and models instead of one dimensional (1D) ones. The ability of solving complex structures within few minutes enhances the use of 2D modeling with the integration of wave motion. In addressing the uncertainty, GIS becomes an important tool in risk assessment by integrating the flood depth, extend and vulnerability issues for definition of the quantitative risk. In this study, 1D and 2D hydraulic modeling is applied and combined with the quantitative vulnerability factors in Dalaman Plain-Turkey. Results show that the area is vulnerable to flood and high monetary damages can be seen in case a flood in the region.

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...
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...
Management of reservoir sedimentation case studies from Turkey
Çetinkaya, Oğuz Kağan; Tiğrek, Şahnaz; Department of Civil Engineering (2006)
Siltation is becoming a big problem as the dams get older all over the world. Conservation and sustainable management of existing reservoirs is gaining more importance than constructing new dams. In this study the program RESCON, which is outcome of a World Bank sponsored project, has been used to examine sediment removal strategies (flushing, hydrosuction sediment removal, dredging and trucking) for four dams of Turkey namely Çubuk I Dam, Bayındır Dam, İvriz Dam and Borçka Dam. Sediment measurements are ma...
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...
Instream flow methodologies : hydrological environmental flow assessment in Pazarsuyu River
Göz, Çağlayan; Usul, Nurunnisa; Department of Civil Engineering (2012)
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 ...
