Physical models can be used to explore the dynamics of very complex systems where the interaction of elementary processes (such as hillslope erosion, river incision and sediment transport) is difficult to predict theoretically or with numerical models, and for which geological observations are insufficient. It is also a tool that can be tailored to test quantitatively various predictions provided that time, space and rheological properties are adequately scaled down. This is the main problem in designing such models, and whilst other scientific domains of earth sciences (tectonics, earth interior dynamics,…) have come with relatively good scaling relationships and materials, the experimental approach in geomorphology lags behind. In this session, we hope to gather researchers using and developing experimental models to elucidate problems related to the evolution of landscape (terrestrial and extra-terrestrial, aerial or submarine) from the scale of elementary processes (hillslope, channels, submarine canyons) to the scale where coupling between climate, erosion/transport and tectonics might be relevant. Technical aspects on how to scale these models, on experimental materials and setup are most welcomed, as well as examples of comparison between experimental results, numerical simulation and dynamics of natural systems. We hope to cover the following subjects: elementary processes of bedrock incision and hillslope processes; dynamics of alluvial and bedrock rivers; landscape evolution by glacial erosion; impact of tectonics and climate on landscape and stratigraphy; coupling between erosion and deformation; dynamics of submarine topography; evolution of Martian relief.
