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

RÉSUMÉ

Phenomenological (macroscale) models are commonly used in analyses of saturated soil systems. In these models, the momentum exchange between the solid and fluid phases is generally accounted for using Darcy's law. A hydromechanical model is presented herein to study the coupled mesoscale pore water flow and microscale solid matrix deformation of granular soils. The fluid motion is idealized using averaged Navier-Stokes equations, and the discrete element method is employed to model soil particles. Fluid-particle interactions are addressed using established semi-empirical relationships. The proposed approach was validated using published experimental results. Numerical simulations were conducted to investigate the liquefaction of soil deposits subjected to a critical hydraulic gradient. Pore water flow through a liquefied coarse sandy soil was shown to deviate from Darcy's law and eventually become locally nonlaminar. At steady state, the associated permeabilities were found to be comparable to those at subcritical conditions.
