1. [Article] Statistical Analysis for Groundwater / Surface Water Interaction at a Drinking Water Well
Drinking water at a certain groundwater well is located at the confluence of a north fork and south fork of a major river. Data was collected to determine if the well is under direct influence by surface ...Citation -
Earth's surface is rapidly urbanizing, resulting in dramatic changes in the abundance, distribution and character of surface water features in urban landscapes. However,the scope and consequences of surface ...

One of the most important purposes of surface water resource management is to develop predictive models to assist in identifying and evaluating operational and structural measures for improving water quality. ...
Citation -
Urban land-use generally alters the hydrologic cycle, leading to changes in the natural flow regime of local streams. Runoff from impervious surfaces and routing of stormwater to streams causes urban streams ...
Citation -
Monitoring surface water temperatures (Tw) in lakes, rivers, and reservoirs is a key component of environmental management and influences water quality by affecting bio-geo chemical reaction rates, altering ...
Citation -
Environmental parameters that influence the isotopic composition of meteoric water (δ18O and δD) are well characterized up the windward side of mountains, where orographic precipitation results in a predictable ...

12. [Article] Hydrogeochemical Evaluation of the Uinta Formation and Green River Formation, Piceance Creek Basin, Northwestern Colorado, USA
The Piceance Creek Basin in northwestern Colorado contains extensive oil shale deposits that produce natural gas and which could potentially yield ~1.5 trillion barrels of shale oil. However, much of the ...Citation -
Dual-satellite crossover data from the Jason-2 and Cryosat-2 altimeter missions are used in a novel approach to quantify stationary and nonstationary tides from time-lagged mean square sea surface height ...

14. [Article] Application of Mathematical Modeling and Computer Simulation for Solving Water Quality Problems
Deteriorated water resources in Central and Eastern Europe call for actions that should be undertaken to improve current conditions and to protect human and environmental health. Mathematical modeling ...Citation -
15. [Article] CE-QUAL-W2, Version 3
CE-QUAL-W2 is a two-dimensional water quality and hydrodynamic code supported by the U.S. Army Engineer Research and Development Center (Cole and Buchak 1995). The model has been widely applied to stratified ...Citation -
16. [Article] Hydrogeologic Investigation of a Pumice Aquifer, Fremont/Winema National Forest, Oregon
The middle Holocene cataclysmic eruption of Mount Mazama blanketed Walker Rim, in south central Oregon, with 270 cm to 300 cm of pumice, causing capture of surface water systems by groundwater, stream ...Citation -
17. [Article] A Method for Processing Acoustic Doppler Current Profiler Velocity Data from Towed, Undulating Vehicles
The utility of the acoustic Doppler current profiler (ADCP) for sampling small time and space scales of coastal environments can be enhanced by mounting a high-frequency (1200 kHz) ADCP on an oscillating ...Citation -
18. [Article] Restriction mapping and expression of recombinant plasmids containing the arsenic resistance genes of the plasmid R45
The trivalent (arsenite) and pentavalent (arsenate) forms of arsenic are introduced into the environment through the use of arsenic in herbicides, pesticides, fertilizers, and the smelting of arsenic-bearing ...Citation -
19. [Article] Characterization of the Shallow Subsurface Geohydrology of the Ni-les'tun Unit on the Bandon Marsh National Wildlife Refuge
The Bandon Marsh is a large marsh restoration project located in southwest Oregon. The land has been previously used for dairy farms and much of the marsh was used for cattle grazing. The goal of the restoration ...Citation -
20. [Article] Investigating the Link Between Surface Water and Groundwater in the Tule Lake Subbasin, Oregon and California
Water allocation in the upper Klamath Basin of Oregon and California has been challenging. Irrigators have increasingly turned to groundwater to make up for surface water shortages because of shifts in ...Citation
