Storage and release of water from seasonal snowcovers and glaciers constitute critical components of the hydrological cycle in many parts of the world. Quantifying, understanding, and predicting the processes that control distribution and ablation dynamics of snow and ice provide ample research challenges, especially in complex mountainous terrain. Snowcover and glacier dynamics are influenced by surrounding topography, vegetation and other land surface characteristics that control accumulation and redistribution processes, as well as local micrometeorological conditions that control energetics and ablation. Accurate modelling of snow and ice melt dynamics requires methods to simulate a large range of physical processes that act and interact at a range of spatial and temporal scales. Advances in these areas are needed and relevant to develop improved tools for water managers concerned with floods, droughts, water supply, hydropower generation, and climate change impacts. This session will bring together experimental and modeling experts to address recent research in snow and ice hydrology.
