C52B:
Observing, Modeling, Diagnosing, and Predicting Hydrological and Earth System Change in Cold Regions II


Submit an Abstract to this Session


Session ID#: 60439

Session Description:
In recent decades warming trends and other changes in climate have driven major and rapid changes in landscapes, ecology, cryosphere, and hydrology, especially in high latitude and mountainous cold regions. Here, the presence of snow, ice, and frozen soils greatly impacts water cycling and Earth system functioning. Understanding of process interactions and behaviour from experimental and observational programs, and improved representation of these processes within physics-based models are key towards diagnosing the complexities of past change and better predicting future responses in system functioning over various time scales. This session invites papers that describe field and modelling studies to address process interactions, the changing nature of hydrological, hydrometeorological and Earth systems in response to climatic drivers, and the diagnosis and prediction of change. Studies dealing with biogeochemistry and the integration of water quality and water quantity monitoring and modelling across cold region landscapes and water bodies are also welcome.
