Sources of water and nitrogen to the Widefield Aquifer, southwestern El Paso County, Colorado
Patrick Edelmann, Doug Cain
1985, Water-Resources Investigations Report 85-4162
The Widefield aquifer near Colorado Springs, Colorado, is recharged primarily by Fountain Creek and, to a lesser extent, by infiltration and percolation of water from the land surface and from groundwater inflow. During the past 20 to 30 years, concentrations of nitrate (as nitrogen) in the Widefield aquifer have increased...

Michael Eberle, A. C. Razem
1985, Water-Resources Investigations Report 85-4205
The hydrologic effects of surface coal mining in unlimited areas is difficult to predict, partly because of a lack of adequate data collected before and after mining and reclamation. In order to help provide data to assess the effects of surface mining on the hydrology of small basins in the...

J.C. Ebbert, K. L. Payne
1985, Water-Resources Investigations Report 84-4093
The quality of water in major aquifers in southwestern Washington was addressed in terms of inorganic-constituent, trace-metal, and fecal-coliform concentrations. Results of this assessment indicate that the groundwater in southwestern Washington can be characterized as soft to moderately hard with a low concentration of dissolved solids. Nitrate was the only...

1985, Water-Resources Investigations Report 85-4190
In a 23 sq mi study area, the Beaver-Pasquiset groundwater reservoir within the Pawcatuck River basin in southern Rhode Island, stratified drift is the only principal geologic unit capable of producing yields > 350 gal/min. Transmissivity of the aquifer ranges from 7,200 to 24,300 sq ft/day. Water table conditions prevail...
Determination of roughness coefficients for streams in Colorado
R.D. Jarrett
1985, Water-Resources Investigations Report 85-4004
Most hydraulic calculations of flow in channels and overbank areas require an evaluation of flow resistance, generally expressed as Manning 's roughness coefficient. The degree of roughness depends on many factors. The report summarizes and relates several methods of estimating roughness and presents additional channel-roughness verification data on higher-gradient streams...
