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...

Diatom Community Dynamics In A Reactivated Antarctic Dry Valley Stream

Kohler , Tyler J 1 ; Stanish , Lee F 2 ; Esposito , Rhea M. 3 ; Simmons , Breana 4 ; McKnight , Diane M 5 1 University of Colorado 2 University of Colorado 3 University of Louisiana at Lafayette 4 Colorado State University 5 University of Colorado...

Evaluating The Chemical Characteristics And Optical Properties Of Atmospheric Wet Deposition To An Alpine Lake And Snowpack

Kim , Hong S 1 ; Williams , Mark W. 2 ; Schmidt , Steven 3 ; Mladenov , Natalie 4 1 INSTAAR 2 INSTAAR 3 INSTAAR 4 INSTAAR There is an urgency to improve our understanding of how water quality in high-elevation catchments is responding to climate change. Clear,...

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...

A Conceptual Model Of Water Quantity Impacts From Insect-Induced Tree Death In Coniferous Forests

Gordon , Eric 1 ; Pugh , Evan 2 1 Western Water Assessment 2 University of Colorado Boulder In snow-dominated regions, forested watersheds often provide a considerable portion of the downstream water resources, and tree death can significantly alter many ecohydrologic processes including transpiration, canopy transmission and interception, subcanopy wind...

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...

Genetic Algorithm Optimization Of Injection And Extraction Patterns Using Two Wells For In-Situ Remediation Of Groundwater

Fuller , Kathleen 1 ; Neupauer , Roseanna M. 2 ; Mays , David C. 3 1 Department of Civil Engineering, University of Colorado Boulder 2 Department of Civil Engineering, University of Colorado Boulder 3 Department of Civil Engineering, University of Colorado Denver Contaminated groundwater remediation may be conducted by...

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...
