Vulnerability Of An Operational Snowmelt Model To Unusual Snow Conditions And Melt Drivers

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...

Entering A New Era Of Water Science And Management: The Maturation Of Snow Remote Sensing

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...

Dissolved Black Carbon In Antarctic Lakes: Chemical Signatures Of Past And Present Sources.

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

Many Objective Decision Support For Water And Environmental Problems Under Deep Uncertainty

Kasprzyk , Joseph 1 1 University of Colorado Boulder 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...

Capturing Hydrologic Regime Changes Over Regional Scales: Lagrangian Sampling And Rapid Hydro Assessment Methodologies

Hill , Alice F 1 1 CU-Boulder 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...

Dynamic Response Of Watershed Subsurface Systems To Extreme Precipitation Events – Implications For The 2013 Colorado Front Range Floods

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

Modeling And Observations Of Luminescence In River Sediment From The US Mid-Atlantic Region: Implications For Obtaining Sediment Transport Information

Gray , Harrison J 1 1 University of Colorado - Boulder 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...

Effects Of Warming On Groundwater Flow In Mountainous Snowmelt-Dominated Catchments

Evans , Sarah 1 ; Ge , Shemin 2 1 University of Colorado Boulder 2 University of Colorado Boulder 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...

River Response To Dam Removal: A Synthesis Perspective

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...

Western Water Assessment: Innovative AVÃûʪ In Partnership With Decision Makers
