Fire, Flood, And Drought: Extreme Climate Events Alter Flowpaths And Stream Chemistry

Sept. 4, 2018

Murphy , Sheila 1 1 U.S. Geological Survey Extreme climate events– such as hurricanes, droughts, extreme precipitation, and wildfires– have the potential to alter watershed processes and stream response. Yet due to the destructive and hazardous nature and unpredictability of such events, capturing their hydrochemical signal is challenging. A five-year...

Toward Improved Reservoir Management Via Hydrologic Uncertainty Quantification

Sept. 4, 2018

Kasprzyk , Joseph 1 1 University of Colorado Boulder Due to climatic and land use change, water managers are increasingly interested in the influence of uncertainty in their systems. Current hydrologic forecasting frameworks often consider variable initial conditions to represent a range of potential conditions, and use statistical models to...

Simulating The Nonlinear Response Of Alpine And Subalpine Snowpacks To Climate Warming

Sept. 4, 2018

Jennings , Keith S 1 ; Molotch , Noah P 2 1 University of Colorado Boulder 2 University of Colorado Boulder It is well known that climate warming invokes nonlinear responses in snow accumulation and melt within the seasonal snow zone. Previous research has shown that higher, colder sites are...

Pipes, Chimneys, And Processors: Examining Thresholds Of Carbon Transport, Reactivity, And Fate In Inland Waters

Sept. 4, 2018

Hotchkiss , Erin 1 1 Biological Sciences, Virginia Tech Despite much research identifying inland waters as active players in the carbon cycle, the relative role of hydrologic transport and in situ transformations in controlling carbon fluxes and fate along aquatic continua is still uncertain. Further, conclusions about the function of...

Science-Action Partnerships To Quantify Changes To Nutrient Cycling And Water Resources And Inform Sustainable Management In California’s $62B Wine Industry

Sept. 4, 2018

Hinckley , Eve-Lyn S. 1 1 Environmental Studies, Institute of Arctic and Alpine Research; CU Boulder California’s wine industry is both a major revenue stream to the State, at $62B per year, and a hydro-biogeochemical manipulation at a grand scale. During the growing (dry) season, winegrowers apply an average of...

Sept. 4, 2018

Hendrickson , Patrick J 1 ; Gooseff , Michael N 2 ; Huryn , Alexander D 3 1 University of Colorado-Boulder 2 University of Colorado-Boulder 3 University of Alabama Aufeis (icings or naleds) are seasonal arctic and sub-arctic features that form through repeated overflow and freeze events of river or...

Assessing The Impacts Of Wildfire On Sedimentation And Runoff In The Colorado Front Range

Sept. 4, 2018

Heldmyer , Aaron J 1 ; Livneh , Ben 2 ; Kampf , Stephanie 3 1 University of Colorado Boulder 2 University of Colorado Boulder 3 Colorado State University Abstract. The complex effects of wildfire disturbances on the quality and availability of water are far-reaching and often difficult to anticipate,...

Alpine Hydrogeology: The Critical Role Of Groundwater In Sourcing The Headwaters Of The World

Sept. 4, 2018

Hayashi , Masaki 1 1 Department of Geoscience, University of Calgary Many of us have been awed by the stunningly beautiful view of alpine lakes and streams – and they are not just beautiful. Nearly half of the world population relies on rivers originating in high mountains for water supply...
