Advances in Observation and Modeling of Ecohydrological Processes in Snow-Covered Forests
Session ID#: 160320
Session Description:
The complex dynamics of snow and ecohydrological processes around forest canopy entail major observational and modeling challenges. Many relevant processes are tightly linked to the canopy structure and vary considerably across small spatial scales, e.g., interception, sublimation and snow melt, soil moisture, evapotranspiration, and radiation transfer through the canopy. A warming climate and more extreme forest disturbances, e.g. fire, insects, and mechanical thinning, are expected to impact these tightly linked processes and potentially alter water availability.
Recent remote sensing technology and modeling techniques provide detailed understanding of forest snow and canopy structure. High-resolution remote sensing datasets have proven useful to represent snow-forest interactions, particularly following variable changes in canopy structure after vegetation disturbance or regrowth.
The session aims to bringing together those interested in ecohydrological processes in snow-covered and often disturbed forests, develop novel experimental methods, provide observational datasets, or advance numerical models.
