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

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

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

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...

Hydrogeologic, Isotopic, And Geochemical Analysis Of Groundwater-Surface Water Interactions Along The Fruitland Outcrop: The Backdrop For Coalbed Methane Development In The Northern San Juan Basin

Kroepsch , Adrianne 1 ; Williams , Mark 2 ; Nydick , Koren 3 ; Gianniny , Gary 4 1 University of Colorado-Boulder 2 University of Colorado 3 Mountain Studies Institute 4 Fort Lewis College There remains considerable uncertainty about how coal bed methane (CBM) production from Colorado’s Fruitland Formation...

Longitudinal Profiles, Neotectonics, And Potential Bedload Transport

Hannon , Mark T 1 ; Kettner , Albert J. 2 ; Syvitski , James P.M. 3 ; Overeem , Irina 4 1 CSDMS, INSTAAR 2 CSDMS, INSTAAR 3 CSDMS, INSTAAR 4 CSDMS, INSTAAR Zones of erosion and deposition, and knowing how to locate them, are of interest to geoscientists,...

Adjoint Based Approach To Quantifying Stream Depletion Due To Aquifer Pumping Using A One-Dimensional Coupled Surface And Groundwater Model

Griebling , Scott A 1 ; Neupauer , Roseanna M 2 1 University of Colorado 2 University of Colorado With growing populations and increased demand for water, it is necessary to ensure that increased pumping of aquifers does not reduce flows in rivers to levels that would limit the availability...

Using Fluorescence Spectroscopy And PARAFAC Analysis To Characterize The Water-Soluble Organic Matter And Associated Dissolved Organic Matter In A First Order Alpine Catchment

Gabor , Rachel 1 ; McKnight , Diane 2 1 University of Colorado-Boulder 2 University of Colorado-Boulder The increasing concentrations of dissolved organic matter observed in many northern latitude regions have potentially significant effects on both ecosystem dynamics and water treatment processes. Many hypotheses for the cause of this change...

The Dynamics Of Hydrology And Mercury In Tributaries Of A Mercury-Contaminated Lake

Ebert , Jessica L 1 ; Driscoll , Charles T 2 1 University of Colorado at Boulder 2 Syracuse University Urban stormwater runoff is a critical water quality problem for older cities in the Northeast, including Syracuse NY. In this study we examined the response of Onondaga Creek to high...

The Effect Of Colloid-Facilitated Transport On Cesium And Srontium Transport In Unsaturated Quartz Sand Columns

Dittrich , Timothy M 1 ; Ryan , Joseph N 2 1 University of Colorado-Boulder 2 University of Colorado-Boulder The presence of small particles (colloids) in natural soil and groundwater systems has been well established. Under certain environmental conditions, the sorption of contaminants to mobile colloids can increase transport in...
