A method to generate small-scale, high-resolution sedimentary bedform architecture models representing realistic geologic facies

Abstract Small-scale (mm to m) sedimentary structures (e.g. ripple lamination, cross-bedding) have received a great deal of attention in sedimentary geology. The influence of depositional heterogeneity on subsurface fluid flow is now widely recognized, but incorporating these features in physically-...
