INVITED KEYNOTE PRESENTATION: Snowmelt Runoff, The Fourth Paradigm, And The End Of Stationarity

Dozier , Jeff 1 1 Donald Bren School of Environmental Science & Management, University of California at Santa Barbara In the 21st century, a crucial question for mountain snowpacks worldwide is: How do we reliably predict snowmelt runoff and associated demand as climate changes, populations grow, land use evolves, and...

INVITED KEYNOTE PRESENTATION: Understanding Our Climate Through Precipitation Measurements

Doesken , Nolan 1 1 Colorado State Climatologist and Senior Research Associate, Director, Fort Collins Weather Station Underlying most work in hydrologic science is a basic knowledge of climatic characteristics of precipitation -- the quantity, frequency, intensity, duration of precipitation as well as information on how precipitation varies geographically, seasonally,...

Use Of Isotopic And Geochemical Tracers To Identify Source Waters And Subsurface Residence Times Within Headwater Catchments In Â鶹¹ÙÍø Creek Watershed, Colorado

Cowie , Rory M 1 ; Williams , Mark W 2 1 University of Colorado and INSTAAR 2 University of Colorado and INSTAAR An outstanding question for snowmelt-dominated watersheds of the western US is the response of stream flow to changes in climate. We know little about mountain aquifers because...

Modeling The Impact Of Climate Change On High Altitude Groundwater Resources

Cochrane , Jessica J 1 ; Ge , Shemin 2 1 University of Colorado 2 University of Colorado It is widely accepted that the global climate is changing, yet our understanding of the effect of climate change on groundwater resources is limited. Many questions remain regarding the size of groundwater...

Application Of A GLM Framework To Model Stream Temperature Attributes In The Sacramento River Basin
