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: 0.6 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

RESUMO

Understanding the wave shape in the near shore region and runup location at the shoreline are crucial to planning and design efforts in coastal engineering because all disasters in the coastal area are related to strong wave actions. A conventional wave gauge (e.g., pressure type or capacitance type) has difficulties in acquiring wave data in this region because the gauge may be out of water for a certain period of time, hence, calibration for the wave gauge is hard to achieve. At the same time, the flow field can be disturbed rigorously by the existence of a wave gauge, especially near a very shallow water region. A nonintrusive-type wave measurement technique is developed by using optical devices and processing the laser-induced image to get precise wave data without disturbing the flow/wave field because there is no gauge within the water body. Getting correct wave runup data or wave data in very shallow water, where an intrusive-type wave gauge is not appropriate, are other advantages for developing the nonintrusive wave measuring technique. Comparing the results with a precise capacitance-type wave gauge proved the laser-induced image wave-measuring system is a precise and reliable wave-measuring system. According to the experimental results, using the new wave-measuring technique can get very satisfactory wave data in the near shore region, where the wave data are not available for an intrusive instrument. The interesting contact line effect at the shoreline that is caused by the complicated interaction between the air-water-solid boundary was observed clearly by using the new wave-measuring technique.
