A real-time flood forecasting system was developed over the Klzlllrmak river basin (KRB) in Turkey by means of a physically-based atmospheric-hydrological model. The real-time flood forecasting system utilizes the weather research and forecasting (WRF) model and the WRF data assimilation (WRFDA) system as its atmospheric component. Real-time global atmospheric forecasting data are obtained from global forecast system (GFS) operated by the national centers for environmental prediction (NCEP). The real-time global atmospheric forecasting data are utilized as initial and boundary conditions of the atmospheric component. The atmospheric component synthesizes real-time upper-air sounding data and ground observations into the initial conditions by the three-dimensional variational (3DVAR) data assimilation system. After the assimilation, the atmospheric component dynamically downscales the real-time global atmospheric forecasting data into 4 km horizontal resolution and hourly temporal resolution. The real-time flood forecasting system is in operation now. Some preliminary forecasted results by the atmospheric component are shown in this presentation.

Hydrodynamic Modeling of Dam-Reservoir Response during Earthquakes
Aydın, İsmail (American Society of Civil Engineers (ASCE), 2011-08-03)
A computational model is developed to analyze the hydrodynamic behavior of dam reservoirs during earthquakes. The mathematical model is based on the solution of two-dimensional (2D) Navier-Stokes equations in a vertical, semi-infinite domain truncated by a far-end boundary condition. A depth integrated continuity equation is used to track the deforming free-surface and ensure global mass conservation. A combination of Sommerfeld nonreflecting boundary and dissipation zone methods is implemented at the far e...
Extreme waves at Filyos, southern Black Sea
Bilyay, E.; Ozbahceci, B. O.; Yalçıner, Ahmet Cevdet (Copernicus GmbH, 2011-01-01)
A wave measurement project was carried out for a new port planned in Filyos, in the Western Black Sea region of Turkey. The measurement at a depth of 12.5 m lasted for a period of two years and 7949 records were obtained. During the analysis, it was noticed that there were 209 records in which H/H(s) ratio was higher than 2.0. These higher waves in a record are called extreme waves in this study. Although the purpose of wave measurement is not to investigate extreme waves, it is believed that studying these...
Short-Term Flood Control and Long-Term Energy Maximization in Multi-reservoir Systems Using Improved Particle Swarm Optimization
Guvengir, Umut; Savaşaneril Tüfekci, Seçil; Altan Sakarya, Ayşe Burcu; Buhan, Serkan (2021-09-01)
In this study, a model is developed for short-term flood control of a complex multi-reservoir system located on one of the largest basins in Turkey. The managing body of the reservoirs requires that short-term real-time flood control is used in conjunction with the long-term operation for energy maximization. For this purpose, a novel operating framework is developed to couple short-term and long-term decisions. The resulting optimization problems are a large scale and nonlinear. Hence, the solution is main...
Slope stability assessment of a re-activated landslide on the Artvin-Savsat junction of a provincial road in Meydancik, Turkey
Topsakal, Ebru; Topal, Tamer (Springer Science and Business Media LLC, 2015-03-01)
The purpose of this study is to determine the most suitable remediation techniques for an active landslide area in Turkey, using a geological engineering assessment of a re-activated landslide that occurred during the construction of the Artvin-Savsat Junction on the Meydancik Provincial Road, at Km: 12 + 200. For this, the geotechnical parameters of the mobilized geological material-which is colluvium along the sliding surface-were determined by back analyses of the landslide at three geological sections. ...
Climate change impacts on meteorological drought using SPI and SPEI: case study of Ankara, Turkey
MEHR, ALI DANANDEH; Sorman, Ali Unal; Kahya, Ercan; Afshar, Mahdı Hesamı (Informa UK Limited, 2019-11-27)
Using regionally downscaled and adjusted outputs of three global climate models (GCMs), meteorological drought analysis was accomplished across Ankara, the capital city of Turkey. To this end, standardized precipitation index (SPI) and standardized precipitation evapotranspiration index (SPEI) were projected under (representative concentration pathway) RCP4.5 and RCP8.5 greenhouse gas scenarios. In general, our results show that Ankara experienced six severe and two extreme drought events during the referen...
