Processes of erosion occurring in natural environment depend on two major factors. The first is the strength of erosion force, e.g. wind, rainfall or water flow. The second is the terrain hardness or its tolerance to erosion forces. In this article we propose a method of modelling terrain erosion process where the force is uniformly distributed over the entire model with local distribution of varying terrain sensitivity. For the simulations we use two-layered terrain model. The first layer contains information about heights distribution (height-field) and simulate topography of the terrain. The second layer stores data defining its hardness (hardness-field) that represents different geological structures in the terrain.
