Title: Using hydrological signals to understand how the subsurface mediates ecosystem productivity and water cycling in California watersheds

Abstract: In upland landscapes, rock uplift and surface erosion create a structured critical zone, defined as the hydrologically active near surface layer that extends from the vegetation canopy down to underlying fresh bedrock. How does the structure of the critical zone – especially beyond shallow soil layers, which are often less important than deeper saprolite and weathered rock for plant water uptake and stream discharge production – control water storage and release to ecosystems? In this talk, I present a synthesis of observational and modeling results from sites across California to address this question. I demonstrate how ecohydrological signals, such as annual plant water use and streamflow, can be used to assess and constrain hydrogeological properties of the critical zone. Results highlight how, in addition to plant physiology and climate, the subsurface is a key regulator of ecosystem productivity, plant response to drought, and stream water availability.
