Blue and Green Water in the Mountains: Water Supply, Extreme Events, and Ecological Responses in Snow and Glacier-fed Catchments

Session ID#: 78500

Session Description:
Mountain snow and ice serve as important hydrologic reservoirs, storing cold season precipitation for melt, runoff, and plants during the growing season. With warming winters, changes in precipitation phase and melt energy are shifting soil water recharge and meltwater hydrographs, with consequences for mountain ecology, water management, and rain-on-snow flood risk. Important questions for mountain regions include: (1) What are key interactions among biota, climate, snow/ice, and water? (2) How do these processes co-evolve or decouple in response to environmental change? and (3) What can we learn from limited observation about how mountain systems respond to long-term shifts? Complex interacting processes and fine-scale climatic variability present significant challenges to answering these questions. We invite contributions addressing linkages between environmental change and cryospheric, hydrologic, and ecological processes in mountain systems.
