The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.0002 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

ABSTRAKT

An analytical equation for velocity distribution in uniform open-channel flows is proposed based on an eddy viscosity with a modified wake correction and on an analysis of shear stress distribution. The proposed equation for the velocity distribution in vertical direction is able to predict the velocity-dip-phenomenon. The new log-wake modified eddy viscosity model is compared with the previous models. The proposed equation i. e., total-dip-modified-log-wake law for velocity distribution is compared with the experimental data obtained by Coleman, Wang and Qian, Lyn and Kironoto and Graf. The total-dip-modified-log-wake law agrees well with the experimental data and predicts the velocity dip position accurately. It has been found that the Coles' wake strength has significant effect on the location of the dip position and the value increases with the increase of dip-correction parameter.
