Numerical simulation of the Çınarcık dam failure on the Orhaneli River

Bağ, Fırat
This thesis analyzes the probable outcome of the fictitious failure of a dam under a set of pre-defined scenarios, within the framework of a case study, the case subject being the Cinarcik Dam located within Bursa Province of Turkey. The failure of the dam is not analyzed neither structural nor hydraulic-wise but is assumed to be triggered when certain critical criteria are exceeded. Hence, the analyses focus on the aftermath of the failure and strive to anticipate the level of inundation downstream of the dam itself. For the purpose of the analyses, the FLDWAV software developed by the National Weather Service of USA is used to spatially and temporally predict the flow profiles, water surface elevations and discharges occurring downstream of the Çinarcik Dam under the defined set of scenarios. Based on these analyses, indicative inundation maps and settlements under risk will be identified, and the thesis study will further address some available pre-event measures that may be taken in advance.

The present study is an attempt to explain the variations in the extent of protection provided to the producers of four selected agricultural crops in Turkey by a set of independent variables representing various economic and political events of the 1962–1983 period. The economic variables were selected in order to assess the divergence between the intentions of the policy makers and their actions as reflected in the level of support actually provided; while the political variables were chosen to assess the...
Numerical modeling of general compressible multi-phase flows
Kalpaklı, Bora; Tarman, Işık Hakan; Özyörük, Yusuf; Department of Engineering Sciences (2013)
In this thesis, some novel methods for solution of compressible, multi-phase flows on unstructured grids were developed. The developed methods are especially advantageous for interface problems, while they are also applicable to multi-phase flows containing mixtures as well as particle suspensions. The first method studied was a multi-dimensional, multi-phase Godunov method for compressible multi-phase flows. This method is based on the solution of a hyperbolic equation system for compressible multi-phase f...

The Bafra alluvial plain, where the Kızılırmak River discharges into the Black Sea, is one of the most critical examples of severe coastal erosion problems in Turkey. The amount of sediment carried by the Kızılırmak River has decreased from approximately 23 million ton per year to 0.46 million tons/year starting from 1960s as a result of construction of flow regulatory structures in the following years. This drastic decrease in the amount of sediment carried by the river resulted in a severe shoreline retre...
Computation and analysis of spectra of large networks with directed graphs
Sarıaydın, Ayşe; Karasözen, Bülent; Jost, Jürgen; Department of Scientific Computing (2010)
Analysis of large networks in biology, science, technology and social systems have become very popular recently. These networks are mathematically represented as graphs. The task is then to extract relevant qualitative information about the empirical networks from the analysis of these graphs. It was found that a graph can be conveniently represented by the spectrum of a suitable difference operator, the normalized graph Laplacian, which underlies diffusions and random walks on graphs. When applied to large...
Numerical modeling of balçova geothermal field
Polat, Can; Parlaktuna, Mahmut; Department of Petroleum and Natural Gas Engineering (2010)
The aim of this study is to construct a numerical reservoir model for Balçova geothermal field, which is located in the İzmir bay area of the Aegean coast. A commercial numerical simulation program, TOUGH2 was utilized with a graphical interface, PETRASIM to model the Balçova geothermal field. Natural state modeling of the field was carried out based on the conceptual model of the field, then history matching of production – injection practices of the field was established for the period of 1996 – 2008. The...
