HAPpy Hour Seminar- Infiltration Depth, Plant Rooting Depth, Hydrologic Continuity and Regolith Flushing

Abstract: How deep does the rain regularly infiltrate into the ground? Do plant roots follow? How much infiltration passes below plant roots and reaches the water-table, flushing the regolith, recharging aquifers and rivers and eventually reaching the ocean? How often?  What are the global patterns of these basic hydrologic variables, and what are the drivers? And what are their implications to global material/energy cycles? I will comment on these questions and show our latest results from global simulations and observations.
