Session ID#: 13942

Session Description:
Preferential flow is a fundamentally important hydrologic process in soils and landscapes that controls a variety of physical, chemical, and biological functions in the Critical Zone. Numerous studies over the past decades have demonstrated the nearly universality of preferential flow and transport in the field across space and time. However, the lack of systematic theory and the existence of conceptual and technological bottlenecks continue to hinder the advancement of preferential flow modeling and prediction. This session welcomes new developments and novel experimental and modeling efforts that shed new light on preferential flow occurrence frequency, organizing principle, flow configuration, pattern prediction, boundary condition, and the link to biogeochemical dynamics and ecological functions in the Critical Zone.
