EP13C:
Experimental Studies in Surface Processes I


Session ID#: 8538

Session Description:
Physical experiments are a useful tool for studying and simplifying the complex natural systems we seek to understand. Experiments allow us to isolate individual variables ranging from grain scale to landscape scale that are often difficult or impossible to measure in the field. Experiments are often scaled to natural landscapes using system characteristic dimensionless numbers. However, many scientists have been able to reproduce natural phenomena without rigorous dynamical scaling. This session aims to represent experimental studies in surface processes across all temporal and spatial scales. We especially encourage submissions that emphasize improvements on understanding experimental scaling and linking experiments to natural systems and numerical models.
