WebThe heterogeneity of hydrofacies is represented as spatial variability on different scales, and it has a significant impact on the behavior of groundwater flow and pollutant transport. However, effectively characterizing hydrofacies heterogeneity on different scales remains one of the most challenging problems in hydrogeology. In this study, an upscaling … WebArithmetic mean Typically used for additive properties, such as porosity, saturation, and net/gross. Harmonic mean Gives the effective vertical permeability if the reservoir is layered with constant permeability in each layer. It works well with lognormal distributions and is sensitive to lower values. Geometric mean phonebuff style https://glynnisbaby.com
