Modeling glacial and fluvial landform evolution at large scales using a stream-power approach

Abstract. Modeling glacial landform evolution is more challenging than modeling fluvial evolution. While several numerical models of large-scale erosion are available, there only a few erosion, and their application over long time spans requires high effort. In this paper, simple formulation which similar to the stream-power model presented. The reproduces occurrence overdeepenings, hanging valleys, steps at confluences least qualitatively. Beyond this, it allows for seamless coupling sediment transport. recently published direct scheme transport can be applied entire domain, where effort moderately higher purely system. Simulations million years on lattices nodes performed standard PCs. An open-source implementation freely available as part OpenLEM.
