Use of sedimentological information for geometric simulation of natural porous media structure

摘要: A geometric simulation method was used to develop a three-dimensional, highly detailed synthetic representation of point bar sediments in the Wabash River system. Geometric methods, comparison well-known second-order stochastic offer advantage being more closely related depositional processes, which are often similarly conceptualized (i.e., described terms shapes discrete bed forms, trends grain size, and spatial relationships defined geologic facies). Multiple scales variation were within sedimentologically prescribed framework, elements established at each scale. The selected based on published field studies including sedimentological form trench active sediments. parameterization allowed for random variability shape descriptors; then generated assimilated by computer. Hydraulic conductivity values assigned reports observed variations size measurements hydraulic conductivity. model, referred as numerical aquifer, is basis extensive experimentation study relationship between natural structure subsurface flow transport.
