Evaluation of surface soil geochemical data and statistical modeling of akarca fula tepe low sulfidation epithermal au-ag mineralization (Bursa), Turkey
Bal, Derya; Karahanoğlu, Nurkan; Department of Geological Engineering (2015)
The Akarca property is dominated by Triassic sedimentary units that tectonically overlie Pre-Triassic basement rocks (schists and marbles). The property displays characteristics of a low sulfidation Au-Ag deposit type in terms of alteration, mineralization and vein textures. The Akarca property is characterized by six primary mineralized zones. Among these zones, Fula Tepe Zone formed the subject of this thesis. The main aim of this dissertation is to evaluate the results of surface soil geochemistry data a...
Optimum design of slurry pipelines
Yıldız, Burhan; Altan Sakarya, Ayşe Burcu; Department of Civil Engineering (2009)
There exist various applications of transportation of slurries through pipelines all over the world. In the present study, the problem is formulated as a "transportation problem" to determine the pipe diameters and amounts of slurry to be transported from the demand (production) points to the processing (factory) points. The minimization of the cost consisting of the pipe and energy cost terms is considered as the objective function to determine the stated decision variables. Pipe cost is given as the funct...
Nonlinearity of the residual shear strength envelope in stiff clays
Maghsoudloo, Arash; Huvaj Sarıhan, Nejan; Department of Civil Engineering (2013)
During shearing of stiff clays, plate-shaped clay particles are parallel-oriented in the direction of shear reaching the minimum resistance of “residual shear strength”. The residual shear strength envelopes of stiff clays are curved, but for practical purposes represented by linear envelopes. This study investigates the nonlinearity of the residual shear strength envelope using experimental evidence (i) from laboratory reversal direct shear tests on two stiff clays (Ankara clay and kaolinite) at 25 to 900 ...
Nonlinear analysis of RC frames retrofitted with structural steel elements
Akpınar, Uğur; Binici, Barış; Department of Civil Engineering (2010)
Deficient concrete structures are serious danger in seismic zones. In order to minimize economical and human loss, these structures should be retrofitted. Selecting suitable retrofitting schemes requires detailed investigation of these systems. Considering these facts, this study aims to calibrate analytical models of systems with chevron braces and internal steel frames; and evaluate their seismic performances. First, analytical models of the frames with braces and internal steel frames were prepared and t...
Operational hydrological forecasting of snowmelt runoff by remote sensing and geographic information systems integration
Tekeli, Ahmet Emre; Şorman, Ali Ünal; Department of Civil Engineering (2005)
Snow indicates the potential stored water volume that is an important source of water supply, which has been the most valuable and indispensable natural resource throughout the history of the world. Euphrates and Tigris, having the biggest dams of Turkey, are the two largest trans-boundary rivers that originate in Turkey and pass throughout the water deficit nations Syria, Iran, Iraq and Saudi Arabia bringing life as well as water all their way. Snowmelt runoff originating from the mountains of Eastern Turk...
