H42C:
Hydrological, Geochemical, and Biological Dynamics in Structural Variable Pathways (SVPs): From Soil Macropores to Fissure/Karst Systems I


Session ID#: 10623

Session Description:
Variably saturated flow and transport in structurally variable pathways (SVPs) poses major hydrologic challenges, and also presents opportunities in terms of capturing their essential character. In some materials (e.g. karst) water acts by dissolution or other processes to alter flow paths; time- and space-dependent characteristics exist in the soil, the bedrock and at the soil-bedrock interface. Even unsaturated flow in SVPs may be very rapid compared to the surrounding media, and is more likely to deviate from Darcy’s law or Richards’ equation. This session solicits abstracts that provide new insights in hydrologic processes in SVPs, compare those processes across varying terrains, and analyze existing methods and theory.
