Geomorphic Response Of Fall River To The 2013 Flood

Aug. 13, 2018

Schutte , Mark 1 1 Olsson Associates In Rocky Mountain National Park, the 2013 flood destabilized segments of Roaring River and deposited an unusually large amount of sand- and gravel-sized sediment near the confluence with Fall River. We initiated field studies of these two rivers in May 2014 to investigate...

Acid Mine Drainage In Colorado: A Wicked Problem With No End In Sight

Aug. 13, 2018

Runkel , Robert L 1 1 U.S. Geological Survey Acid Mine Drainage (AMD) from abandoned mine lands contaminates streams and rivers throughout the Colorado Mineral Belt. Much of this contamination has persisted for decades and is likely to continue given the impediments to cleanup that are present at most sites...

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

Aug. 13, 2018

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

Aug. 13, 2018

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...
