Freeze and cherry hydraulic conductivity
WebA new model for the hydraulic conductivity is introduced that focuses on the relationship between the coarse-fine soil mixing ratio and the hydraulic conductivity of the mixture. For the model verification, permeability tests were conducted. ... Freeze and Cherry present the Kozeny–Carman equation with d m instead of S 0 in . WebWhen these data are not available, hydraulic conductivity is estimated based on grain size or a published range of values for common geological media (Freeze and Cherry, 1979). As hydraulic conductivity can vary over several orders of magnitude for the same type of material or even in the same aquifer, understanding the validity of the data and ...
