Scientific understanding of individual erosional physical processes controlling soil detachment, transportation, and deposition is vital when developing methods and conservation alternatives to minimize the impacts associated with soil degradation. Research is needed to quantitatively assess the spatiotemporal impact of linked sediment sources and anthropogenic/climatic external factors on gully emergence, soil loss, and landscape degradation. This session will focus on recent studies supporting improved understanding of physical processes, their impact locally, their off-site effects on sedimentation, and subsequent development of mitigation strategies. Specifically, we welcome studies on: novel monitoring and measuring methods, multi-scale gully/rill identification, experimental studies, predictive modeling efforts, geomorphometry, anthropogenic and climatic controlling factors, visualization techniques, Earth and planetary processes, and hydrological and sediment connectivity.
