H027 - Advancing understanding of mountainous critical zones through observations and experiments
Globally, mountainous critical zones (CZs) provide important water and ecosystem services to downstream valley fill aquifers. However, a thorough understanding of surface and subsurface water quality and quantity and their relation to ecosystem services is presently not available. Lack of high-density observations of hydrologic fluxes, environmental tracers, water chemistry, and mineral weathering rates in mountainous regions further contribute to this knowledge gap. 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 to estimate the depth of active groundwater circulation zone?; and (iii) what are the potential consequences of climate warming, extreme weather events, and wildfires on groundwater recharge and discharge processes and water quality? Therefore, this session is intended to bring together researchers and scientists with diverse backgrounds and experiences to advance the understanding of mountainous CZs through observations and numerical experiments.
