Rapid unsaturated zone flow in porous and fractured media
Session ID#: 157905
Session Description:
The unsaturated zone has a crucial role in subsurface processes that in turn impact soil moisture availability, groundwater quality and quantity, and ecosystem function. Water that infiltrates at the land surface will be transported by various mechanisms through the unsaturated zone. For example, water may move rapidly through vertical preferential flow paths, laterally along lithological boundaries, or more slowly as diffuse flow through soil or rock matrix. Predicting where water goes and how fast is crucial for aquifer recharge, contaminant transport, hazards, and other hydrologic issues. Different theoretical and experimental approaches have been developed to increase knowledge of this portion of the subsurface but still there are gaps in comprehension and quantification of flow processes that occur in the unsaturated zone. The session encourages contributions addressing this topic that use approaches such as unique case studies, innovative methodologies, or novel field and laboratory tests so to spark discussion on moving unsaturated zone science forward. Contributions of both theoretical and experimental studies are welcome to increase the knowledge of how fluids and substances move in the unsaturated zone differently from the traditional theories and tools. Particularly welcome are contributions dealing with preferential flow, new experimental observation tools for their evidence and new theoretical formulation for their prediction. Also studies other studies are welcome to provide an overview of newest approaches to better understand mechanisms that act in the unsaturated zone.
