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 ÃÛÌÇÖ±²¥ 2 University of ÃÛÌÇÖ±²¥ 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 ÃÛÌÇÖ±²¥ 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 ÃÛÌÇÖ±²¥-Boulder 2 University of ÃÛÌÇÖ±²¥-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 ÃÛÌÇÖ±²¥ 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 ÃÛÌÇÖ±²¥-Boulder 2 University of ÃÛÌÇÖ±²¥-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...
