Conference Object 14th of the International Conference on Hydroscience and Engineering, Iche 2022: Proceeding Book(Izmir Institute of Technology, 2022) Elçi, Şebnem; Bombar, Gökçen14th of the International Conference on Hydroscience & Engineering, ICHE 2022 will be held in Izmir, Turkey on 26-27 May, 2022. The International Conference on Hydroscience & Engineering began in Washington DC in 1993, and followed by Beijing hosted ICHE in 1995, Cottbus (1998), Seoul (2000), Warsaw (2002), Brisbane (2004), Philadelphia (2006), Nagoya (2008), Chennai (2010), Orlando (2012), Hamburg (2014) Tainan (2016) and Chongqing (2018). These conferences provided a common ground researchers and engineers to report and discuss the latest scientific advancements and practitioner’s solutions in hydroscience and engineering. ICHE 2022 conference aims to bring together researchers and practicing engineers to share the latest scientific and technological advancements in hydroscience and engineering, and will provide networking opportunities for future activities. Participants will be able to hear experts in the field discuss the latest achievements in issues relevant to Hydro-Engineering for Sustainable Development.Article Citation - WoS: 7Citation - Scopus: 9Calculation of the Time-Varying Mean Velocity by Different Methods and Determination of the Turbulence Intensities(Academic Journals, 2010) Bombar, Gökçen; Güney, Mehmet Şükrü; Tayfur, Gökmen; Elçi, ŞebnemThe raw velocity data for both stream-wise and transversal directions in unsteady flows, which are formed by generating input hydrograph, are obtained by using a flow tracker. The same hydrograph is generated 15 times and the mean values are found by calculating the average of all hydrographs. The time varying mean is obtained by using FFT, moving average, wavelet and EMD methods. The best time varying mean is selected according to prescribed criteria. Then, the 15 time series are processed and the stream-wise and transversal turbulence intensities are obtained. The mean of the product of fluctuations is also determined. © 2010 Academic Journals.
