Viscous flow simulation of geological bodies

This paper presents the results of numerical simulation of geological processes distinguished by their proceeding velocities into ten orders. One study case is the gold placer dynamics in a river valley. Another is a fast-moving ice-debris mudflow. In both study cases, the transported material is considered as an independent flow of solid particles free of host rocks. In order to make a mathematical presentation of such a flow, a set of viscous compressed liquid equations is used. Numerical experiments results demonstrate their sufficient similarity with on-site data obtained for a natural placer deposit and an ice-debris mudflow.
