Raleigh , Mark S. 1 ; Deems , Jeffrey S. 2 1 CU / CIRES / NSIDC 2 CU / CIRES/ NSIDC In the mountainous western United States, operational runoff forecasting centers typically use streamflow observations to calibrate snow models over multi-decadal periods to capture the mean snow accumulation and...

Painter , Thomas H. 1 1 Jet Propulsion Laboratory/California Institute of Technology Snow cover and its melt dominate regional climate and water resources in the world’s mountainous regions, providing for critical agricultural and sustaining populations in otherwise dry regions. Snowmelt timing and magnitude in mountains tend to be controlled by...

Khan , Alia 1 ; Jaffe , Rudolf 2 ; Ding , Yan 3 ; McKnight , Diane 4 1 CU-Â鶹ӰԺ/INSTAAR 2 Florida International University 3 Florida International University 4 CU-Â鶹ӰԺ/INSTAAR The perennially ice-covered, closed-basin lakes in the McMurdo Dry Valleys, Antarctica, serve as sentinels for understanding the fate of...

Kasprzyk , Joseph 1 1 Â鶹ӰԺ In environmental planning problems, decision makers' goals often fundamentally conflict. Faced with limited budgets, planners realize that increasing their systems' performance could cause increased costs, negative impacts to the environment, or conflicts among stakeholders. Multi-objective decision support techniques are increasingly used...

Hill , Alice F 1 1 CU-Â鶹ӰԺ Remote mountain rivers are increasingly under development threat as the low hanging fruit of hydropower dam sites -- ones with easy access and whose rivers have large head potential -- have been picked. Often little is known about the hydrologic regimes of rivers...

Henning , Steven 1 ; Ge , Shemin 2 1 Â鶹ӰԺ 2 Â鶹ӰԺ In September 2013, the Â鶹ӰԺ Creek watershed (BCW) was severely affected by a 1000-year precipitation event when 17 inches of rain – nearly the annual average – fell over Â鶹ӰԺ, Colorado,...

Gray , Harrison J 1 1 University of Colorado - Â鶹ӰԺ Obtaining quantitative sediment transport information, such as transport rates, virtual velocity, and characteristic scales, is an important goal of the hydrologic and geomorphic sciences. This information is useful for improving river infrastructure such as reservoirs and understanding the pace...

Evans , Sarah 1 ; Ge , Shemin 2 1 Â鶹ӰԺ 2 Â鶹ӰԺ In mountainous regions, warmer air temperatures have led to an earlier onset of spring snowmelt and lower snowmelt rates because snow melts at a slower rate earlier in the year when...

East , Amy E 1 1 U.S. Geological Survey The last several decades have seen a substantial increase in the number of dams removed in the U.S., including the recent removal of large dams impounding millions of cubic meters of sediment. Both dam emplacement, and eventual dam removal, can be...
