In this study, the HBV model is applied on the upper Euphrates basin in Turkey. Individual sensitivity of the parameters is analyzed by calibrating the model using the Multi-Objective Shuffled Complex Evolution (MOSCEM) algorithm. The calibration is performed against snow cover area (SCA) in addition to runoff data for the water years 2009, 2010, 2011 and 2012. Detailed validation studies are also performed for the snow products namely snow recognition (H10) and snow water equivalent (H13) over Turkey and Austria. In this study signature metrics, which are based on the flow duration curve (FDC) are used to see the performance of the model for low flows. The sensitivity analysis of the parameters around the calibrated optimum points showed that parameters of the soil moisture and evapotranspiration have a strong effect in the total volume error of the model. The parameters from the response and transformation routines have a significant influence on the peak flows. It is observed that the parameters of snow routine have strong effect in high flows and total volume. Besides the Shuffled Complex Evaluation Method in the calibration of the model, multi-metric evaluation framework, which represent the different phases of the hydrograph precisely, is used. A stepwise evaluation is done with commonly used statistical performance metrics (Nash-Sutcliffe, Percent Bias) and signature metrics, which are based on the flow duration curve. Validation of the model is performed for the water year 2013.

The use of fractal geostatistics and artificial neural networks for carbonate reservoir characterization
Yeten, B; Gumrah, F (2000-11-01)
In this study, a carbonate oil reservoir located in the southeast part of Turkey was characterized by the use of kriging and the fractal geometry. The three-dimensional porosity and permeability distributions were generated by both aforementioned methods by using the wireline porosity logs and core plug permeability measurements taken from six wells of the field. Since classical regression (lognormal or polynomial) and geostatistical techniques (cross variograms) fail to estimate permeability from wireline ...
A Case Study for Determination of Hydrological Parameters in HEC HMS In Computing Direct Runoff
Akay, Hüseyin; Baduna Koçyiğit, Müsteyde; Yanmaz, Ali Melih (null; 2016-09-23)
This study deals with the computation of the direct runoff of a precipitation pattern recorded in a watershed in Western Black Sea Region, Turkey. The aim is to perform a hydrological parameter evaluation using HEC-HMS for a basin with an outlet at Bayıryüzü stream gaging station situated close to Ulus town. The basin is highly mountainous along the rivers and forestry. The basin takes large amounts of rain all year round and the runoff of the basin flows into Ulus stream where more frequent flooding with d...
The analysis of current and future climate projections of Türkiye and the large-scale Eastern Mediterranean Black Sea Region in the coarse and high resolutions
Bağçacı, Soner Çağatay; Yücel, İsmail; Department of Civil Engineering (2023-3-03)
This thesis mainly focuses on climatic change over Türkiye and the Eastern Mediterranean Black Sea (EMBS) region with three-legged studies utilizing cutting-edge global climate models (GCMs) and reanalysis. The first study unfolds the future projections of Türkiye under the medium and high emission scenarios by the latest Coupled Model Intercomparison Project Phase 6 (CMIP6) GCMs. The second study conducts sensitivity tests with a 60-model physics combination of the Weather Research and Forecasting (WRF) mo...
A comparative study of force-deformation relationship of FRP-confined concrete columns
Erdil, Barış; Akyüz, Uğurhan; Yaman, İsmail Özgür; Irfanoglu, A. (null; 2011-10-26)
In this study, the FRP-confined concrete models for prismatic members given in the ACI440.2R-08 and Turkish Earthquake Code (TEC2007) are compared with the experimental data taken from the literature. It is found that TEC2007 assumes only hardening behavior for concrete strengthened with FRP. Although ACI440.2R-08 assumes a hardening and softening behavior depending on the confinement-effectiveness, the limit separating the hardening and softening must be improved to predict the behavior well. The assumptio...
The experimental analysis on the Late Quaternary deposits of the Black Sea
Tekiroglu, SE; Ediger, V; Yemenicioglu, S; Kapur, S; Akca, E (Elsevier BV, 2001-01-01)
Holocene sediments taken from the south-eastern and western Black Sea have been investigated in relation to their geochemical, sedimentological and mineralogical characteristics. Their textures are characterized by their low amount of sand, upward-increasing silt and downward-increasing clay contents. While the terrigenous materials transported from Anatolian volcanic-based sources and European alluvial sediments form the shore deposits, the deep-sea sediments mainly consist of the marine biological product...
