A key goal within geomorphic research is understanding the links between topographic form, erosion rates, and sediment production, transport and deposition. Numerical modelling, by allowing the creation of controlled analogues of natural systems, provides exciting opportunities to explore landscape evolution and generate testable predictions. In this session, we invite contributions that use numerical modelling to investigate landscape evolution in a broad sense, and over a range of spatial and temporal scales. We welcome studies using models to constrain one or more of: erosion rates and processes, sediment production, transport and deposition, and sediment residence times. There is no geographical restriction: studies may be focused on mountain environments or sedimentary basins, or they may establish links between the two; studies beyond planet Earth are welcome too.
