Quantifying Stream Depletion Due To Aquifer Pumping

Aug. 20, 2018

Neupauer , Roseanna M 1 ; Grielbing , Scott A 2 1 University of Colorado 2 University of Colorado Groundwater withdrawals for drinking water supplies, irrigation, and other uses can lead to depletion of aquifers. If the aquifer is hydraulically connected to a stream or river, groundwater withdrawals can also...

Spatial And Temporal Variations In Stream Chemistry After Wildfire

Aug. 17, 2018

Murphy , Sheila F 1 ; Writer , Jeff H 2 2 Presenting Author 1 U.S.G.S. 2 U.S.G.S. ; University of Colorado Past studies of stream chemistry after wildfire are conflicting. Some studies show increases in pH, turbidity, nutrients, metals, and other constituents, while others report little impact. Many of...

The Geomorphology Of Braided Streams In The Greater Yellowstone Region

Aug. 17, 2018

Mueller , Erich R 1 ; Pitlick , John 2 1 Dept. of Geography, University of Colorado 2 Dept. of Geography, University of Colorado Braided streams and rivers are relatively rare in the Rocky Mountains of the Western U.S., except in the Yellowstone region of northwest Wyoming. This raises the...

A Method Of Predicting Peak Discharges For Areas Burned By The Fourmile Canyon Wildfire

Aug. 17, 2018

Moody , John A 1 1 U.S. Geological Survey Extreme floods often follow wildfire in mountainous watersheds. The peak discharge for these post-wildfire floods has been shown to correlate with rainfall intensity. The relation between rainfall intensity and peak discharge per unit basin area is based on data from several...

Parasitic And Infectious Disease Responses To Changing Global Nutrient Cycles

Aug. 17, 2018

McKenzie , Valerie J. 1 1 University of Colorado Parasitic and infectious diseases are a significant threat to human, livestock, and wildlife health and are changing dramatically in the face of human-induced environmental changes such as those in climate and land use. In this talk, I explore the little-studied but...

Hydrologic Connectivity Between Landscapes And Streams

Aug. 17, 2018

McGlynn , Brian 1 1 Montana State University The relationships between landscape characteristics, water redistribution, and catchment runoff dynamics remain poorly understood. Hydrologic connectivity between catchment upland and near stream areas is essential for the transmission of water and solutes to streams and controls both the magnitude and signature of...
