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: 1.4 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 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: 2.2 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: 0.00034 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: 0.46 SJR: 0.333 SNIP: 0.606 CiteScore™:: 3.1 H-Index: 31

摘要

Large-scale prediction of events such as coastal inundation, flooding, and dam collapse is becoming increasingly necessary from both a geophysical and geoengineering standpoint. Current computational models can only capture large-scale flow events and are unable to resolve three-dimensional mesoscale local flow features. We present a multiscale coupled fluid method, with large-scale flow over the full domain coupled with a smaller-scale model to more accurately resolve local flow features in regions of interest. The macroscale model uses a finite volume method based on the shallow water (SW) formulation. This is coupled to a mesoscale smoothed particle hydrodynamics (SPH) method for solving the three-dimensional Navier-Stokes equations for the fluid flow. We show the viability of this multiscale method for predicting both large-scale and smaller-scale flow effects in geophysical flow applications.
