Session Proposal: Advancing understanding of mountainous critical zones through observations, numerical experiments, and large-scale synthesis (AGU25)

H035
Advancing understanding of mountainous critical zones through observations, numerical experiments, and large-scale synthesis

Session ID#: 248110

Session Description:
Yet, a thorough understanding of surface and subsurface water and solute fluxes  and their relationships to snowpacks, forest health, and downstream water supply remains   limited due to a lack of high-density and long-term observations of hydrologic fluxes, environmental tracers, water chemistry, and mineral weathering rates. Here, we solicit presentations that address important research questions related to mountainous CZs such as: (i) what are the spatio-temporal variability of mountain flow paths?; (ii) How do changes in precipitation form and rate under a warming climate affect groundwater recharge/discharge processes? (iii) how to estimate the active groundwater circulation depth in mountain aquifers?; and (iv) what are the potential consequences of climate warming, extreme weather events, and wildfires on water quantity and quality? This session is intended to bring together researchers with diverse backgrounds/experiences to advance the understanding of mountainous CZs through observations, numerical/conceptual experiments, and large-scale synthesis projects.
