Lithology, Sediment Supply, And Channel Adjustments In Three Northern Rocky Mountain Streams

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...

Impacts Of Vegetation Distribution On Snow Accumulation And Snowmelt

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...

Potential Impacts Of Climate Change For Western U.S. Ski Areas: Projections For Aspen And Park City In The 21st Century

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...

Thirty Years In The Bull's-Eye: A Climatology Of Meter-Class Snow Storms In The Front Range Foothills

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...

INVITED KEYNOTE PRESENTATION: Adapting The Water Paradigm To A Changing World

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...

INVITED KEYNOTE PRESENTATION: Snowmelt Runoff, The Fourth Paradigm, And The End Of Stationarity

Dozier , Jeff 1 1 Donald Bren School of Environmental Science & Management, University of California at Santa Barbara In the 21st century, a crucial question for mountain snowpacks worldwide is: How do we reliably predict snowmelt runoff and associated demand as climate changes, populations grow, land use evolves, and...

INVITED KEYNOTE PRESENTATION: Understanding Our Climate Through Precipitation Measurements

Doesken , Nolan 1 1 Colorado State Climatologist and Senior Research Associate, Director, Fort Collins Weather Station Underlying most work in hydrologic science is a basic knowledge of climatic characteristics of precipitation -- the quantity, frequency, intensity, duration of precipitation as well as information on how precipitation varies geographically, seasonally,...
