Terrain morphology has been on the radar of Computer Graphics for more than twenty years and various techniques for its modeling have been presented. These approaches range from fractal and multifractal terrain generation to physically-based models of erosion and weathering. Of all the weathering phenomena that can be observed in Nature, hydraulic erosion has the most visual importance. We will focus on hydraulic erosion in our presentation and we will describe a technique that is rooted in a generalized solution to modeling hydraulic erosion using ideas from fluid mechanics. The simulations show the terrain morphogenesis and can be used for animations as well as for static scene models generation.
