Mueller , Erich R. 1 ; Pitlick , John 2 1 Department of Geography, University of Colorado 2 Department of Geography, University of Colorado Stream channel morphology and sediment textures are a product of the basin-wide delivery of sediment and water. Differences in sediment supply, particularly bed load, between watersheds...

Molotch , Noah 1 1 Geography and INSTAAR, CU-Boulder New remote sensing and in situ measurement capabilities afford improved understanding of distributed ecohydrological processes in mountainous regions. In this regard, distributed ecohydrologic instrument clusters allow us to observe micro-scale variability in snow-vegetation interactions. Clusters deployed in the Central and Southern...

McIntyre , Heather M 1 ; Barry , Roger G 2 1 CU-Boulder 2 CU-Boulder Snow covered area (SCA) represents the largest single component of the cryosphere that fluctuates seasonally. For the mountain west, the distribution and storage of snow is largely within the alpine and subalpine environments known to...

Lowry , Liz 1 1 Leeds School of Business and Environmental Studies Program, CU-Boulder The Colorado River supplies water and electricity to about 27 million people throughout the American Southwest and provides irrigation for nearly 4 million acres of land in the region. Through diligent water management practices, supported by...

Lazar , Brian 1 ; Williams , Mark 2 1 Stratus Consulting Inc., Boulder, Colorado 2 Department of Geography and Institute of Arctic and Alpine Research, University of Colorado, Boulder, Colorado We evaluate how climate change resulting from increased greenhouse gas (GHG) emissions may affect snow coverage for two case...

Langston , Abigail L 1 ; Tucker , Gregory E 2 1 University of Colorado 2 University of Colorado The processes that form the weathered bedrock profile in mountain catchments are not well understood and directly influence the evolution of mountain topography. Our study focuses on the landscape evolution of...

Keen , Richard A. 1 1 University of Colorado Although the Colorado Front Range can be considered a semi-arid climate zone, it is subject to occasional large snowfalls. About once every two years, on average, a single storm will leave one to two meters of new snow in the foothills...

Jones , Tyler R. 1 ; White , James 2 1 Environmental Studies & INSTAAR, CU-Boulder 2 Geological Sciences & INSTAAR, CU-Boulder Ice cores at Siple Dome, West Antarctic receive the majority of their precipitation from Pacific Ocean moisture sources. Pacific climate patterns, particularly the El Niño-Southern Oscillation, affect the...

Hellmuth , Molly 1 1 International Research Institute for Climate and Society (IRI) at the Earth Institute of Columbia University Achieving water security is a major challenge of the century, particularly in developing country contexts. Population growth and economic development are significantly increasing water demands; while decreasing water quality is...
