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 devastating results are observed in the further downstream area. In order to improve the understanding of the hydrological response of various precipitation patterns in this basin, HEC-HMS, a hydrological model used to simulate hydrological processes in a watershed is applied. In this study, the hydrological model is set up for two flood events recorded in the area, one is used for calibration while the other one is used for validation of the hydrology related parameters of the model. The simulations are found to be encouraging considering that this is a pioneering attempt of using such a model for the area

Comparison of Source Regions Affecting SO42- and NO3- Concentrations at the Eastern Mediterranean and Black Sea Atmospheres Dogan, G.; GÜLLÜ, GÜLEN; Karakas, D.; Tuncel, G. (Bentham Science Publishers Ltd., 2010-01-01) In this study, source regions of atmospheric sulfate and nitrate in rural areas at the Black Sea and the Mediterranean coasts of Turkey are compared. Stations on the Black Sea and Mediterranean Sea are located at Amasra and Antalya regions, respectively. Source regions of SO42- and NO3- are determined by using potential source contribution function (PSCF). Statistical significance of source regions assigned by PSCF were assured using bootstrapping with 3000 iterations. Source regions affecting sulfate and n...
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...
The Use Of Back Trajectory Cluster Analysis Withpm2.5 Composition At The Eastern Black Sea Of Turkey Balcılar, İlker; Zararsız, Abdullah; Doğan, Güray; Tuncel, Süleyman Gürdal (2017-11-04) In this study, the influence of synoptic-scale atmospheric transport patterns on observed levels of trace elements at Eastern Black Sea region of Turkey was examined. Daily PM2.5 samples were collected at station (40°32’34”N, 39°16’57”E) on the Eastern Black Sea region of Turkey and collected samples were analyzed with ICP-MS for trace element composition. Five-day long back trajectories for March 2011 to December 2013 were calculated for 3 different arrival heights, 100m, 500m and 1500m, and combination of...
A sequence stratigraphic approach to the depositional history analysis of the upper eocene sedimentary succession, northwest of the thrace basin, Turkey Sünnetçioğlu, Mehmet Akif; Altıner, Demir; Department of Geological Engineering (2008) This study investigates the depositional history of the Late Eocene sedimentary record in the northwest of the Thrace Basin in a sequence stratigraphic approach and estimates the contribution of regional tectonics, basin physiography and eustasy. Late Eocene sedimentary succession was analyzed in two third-order sequences based on two major data sets; seismic reflection and well data sets. Depositional Sequence-1, represented by progradational stacking patterns, comprises the coarse-grained “Hamitabat” turb...
Modeling the influence of hydrodynamic processes on anchovy distribution and connectivity in the black sea Karadeniz'deki hamsi dağılımı ve bölgeler arası bağlantısı üzerine hidrodinamik proseslerin etkisinin modellenmesi Fach Salihoğlu, Bettina Andrea (2014-01-01) Dispersal mechanisms of Black Sea anchovy larvae (Engraulis encrasicolus ponticus) across the Black Sea were studied with an individual based anchovy larvae model embedded in a Lagrangian model using surface currents calculated from daily dynamic height topography maps of altimeter data during a period of three years (2001-2003). Particles representing anchovy eggs were released at different sites during June to August and their movement was tracked over time. Drifters were advected for 36 days, representin...
