Early Snowmelt Decreases Ablation Period Carbon Uptake In A High Elevation, Subalpine Forest, Niwot Ridge, Colorado, USA

Winchell , Taylor S 1 ; Molotch , Noah P 2 ; Barnard , David M 3 1 CU Â鶹¹ÙÍø The snow ablation period is a time of great potential for carbon uptake in high-elevation, subalpine forests. During this period, water availability associated with snowmelt promotes photosynthetic carbon uptake, while...

Linking Sap Flow And Stable Isotope Techniques To Understand Transpiration Dynamics In A Semiarid Shrubland

Szutu , Daphne J 1 ; Papuga , Shirley A 2 1 Â鶹¹ÙÍø, INSTAAR 2 University of Arizona Dryland ecosystems account for nearly 40% of terrestrial biomes, and understanding transpiration dynamics in these environments is critical to understanding how climate change will impact global water and carbon...

A Physically Based Modeling Framework For Analyzing The Effects Of Climate Change And Land-Cover Disturbance On Suspended Sediment Transport In The Colorado Front Range

Stewart , Jenna 1 ; Livneh , Ben 2 1 University of Colorado, Â鶹¹ÙÍø and CIRES 2 University of Colorado, Â鶹¹ÙÍø and CIRES Temperatures in Colorado are projected to rise by between +2.5?F and +5?F by 2050, increasing the severity of droughts, heat waves, and wildfire vulnerability. These changes present...

Geomorphic Response Of Fall River To The 2013 Flood

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

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...

Chemostatic Cradle To Grave: Dissolved Organic Matter And The Biogeochemical Impacts Of The 2013 Â鶹¹ÙÍø Flood
