H31H:
The Hydrology–Vegetation–Climate Nexus: Identifying Process Interactions and Environmental Shifts in Mountain Catchments I Posters


Session ID#: 8586

Session Description:
The hydrology‒vegetation‒climate nexus in mountain environments presents an important indicator of global environmental change. However, observations in these regions remain limited and typically confined to non-vegetated areas.  A need therefore exists to (1) improve knowledge of ecohydrological and hydroclimatological baseline conditions, (2) identify how perturbations in vegetation and climate processes interact with hydrology, (3) discriminate between short-term (e.g., multi-year) variability and long-term (e.g., multi-decadal) shifts, and (4) evaluate how vegetation, water and energy processes co-evolve to determine variability and system change.  We invite contributions investigating the response of hydrologic fluxes (e.g., precipitation, evapotranspiration, streamflow) and storages (e.g., soil moisture, snowpack) to short- or long-term changes in vegetation (e.g., forest disturbances, land use change) and climate (e.g., change and natural variability, energy availability), and how hydrologic change consequently impacts local vegetation in mountainous catchments.  We welcome studies that employ mechanistic modeling, field observations, and/or remote sensing at plot to catchment scales.
