Design of coastal structures in Turkey depends on wind measurements since on-site wave measurements either do not exist or very limited. Two of the most commonly used wind data sets, meteorology and ECMWF, are decided to be compared and analyzed in terms of extreme wave characteristics to see their effects on design process when different data sets are utilized. For this purpose, seven points are selected along western coast of Black Sea in Turkey and both data sets are acquired from their respective sources. These data are re-arranged and organized to make them compatible with programs necessary for analysis, namely wind.exe and W61. For each location, graphical and numerical comparisons are made by plotting scatter graphs and wind roses for visualization and extreme analysis for numeric calculations. Obtained results and previous studies around selected regions are compared and results are presented. Also, an additional research on historical storm events based on online sources of local and national media is presented and results are compared with available data sets.

Polat, Çağrı; Yalçıner, Ahmet Cevdet; Özyurt Tarakcıoğlu, Gülizar; Department of Civil Engineering (2015)
In Turkey, due to lack of on-site wave measurement data, design of coastal structures primary relies on wind measurements. Meteorology and ECMWF are the most commonly used data sources for the data sets, which provide valuable information about wind and wave characteristics. In the scope of this research, these two data sets are chosen to be analysed and compared according to their extreme and long term wave characteristics, in order to see different data sets impact on design process. In this study, seven ...
Comparison of wind and wave sources for turkish coasts
Esen, Mustafa; Ergin, Ayşen; Department of Civil Engineering (2014)
Hourly wind measurements are the most important and commonly used data to estimate wave climate for Turkish coasts. There are several data sources, available for coastal engineers in Turkey, among which hourly wind measurements of Turkish coastal meteorological stations (TCMSs) are the most easily obtained and used data. However, due to several features and factors, the overall performance of TCMSs’ representability for onshore winds is low. Therefore, a need arises to search and use alternative wind data s...
Analysis of long term trends of precipitation estimates acquired using radar network in Turkey
Yılmaz, Mustafa Tuğrul; Yücel, İsmail; Yılmaz, Koray Kamil (null; 2016-04-17)
Precipitation estimates, a vital input in many hydrological and agricultural studies, can be obtained using many different platforms (ground station-, radar-, model-, satellite-based). Satellite- and model-based estimates are spatially continuous datasets, however they lack the high resolution information many applications often require. Station-based values are actual precipitation observations, however they suffer from their nature that they are point data. These datasets may be interpolated however such ...
Prediction of input energy spectrum: attenuation models and velocity spectrum scaling
Alici, F. S.; Sucuoğlu, Haluk (Wiley, 2016-10-25)
Recent improvements in performance-based earthquake engineering require realistic description of seismic demands and accurate estimation of supplied capacities in terms of both forces and deformations. Energy based approaches have a significant advantage in performance assessment because excitation and response durations, accordingly energy absorption and dissipation characteristics, are directly considered whereas force and displacement-based procedures are based only on the maximum response parameters. En...
Evaluation of site conditions for the Ankara Basin of Turkey based on seismic site characterization of near-surface geologic materials
Kockar, M. K.; Akgün, Haluk; Rathje, E. M. (Elsevier BV, 2010-01-01)
Regional site conditions relevant for seismic hazard studies can be derived from various geologic, seismologic, and geotechnical sources. In this study, site conditions are derived for the Ankara Basin in Turkey by merging in-situ seismic measurements of dynamic properties, geologic information, and some geotechnical boring information. Field seismic refraction surveys were performed at 259 sites in the project area to classify and characterize Plio-Pleistocene fluvial deposits and Quaternary alluvial and t...
