Evaluation of a hydrograph-shifting method for estimating suspended-sediment loads in Illinois streams
L.R. Frost, L.J. Mansue
1984, Water-Resources Investigations Report 84-4037
A hydrograph-shifting method for estimating monthly and annual suspended-sediment loads was applied to suspended-sediment records for 12 streams in Illinois. Transport equations for each station were developed and synthetic sediment-discharge hydrographs were then generated by using these transport equations and records of daily streamflow. Hydrographs were shifted to measured values...
Ground-water conditions in the Cottonwood-West Oakley Fan area, south-central Idaho
T.K. Edwards, H.W. Young
1984, Water-Resources Investigations Report 84-4140
Intensive groundwater development in the Cottonwood-West Oakley Fan area, Cassia County, Idaho, has resulted in rapid water-level declines and establishment of two critical groundwater areas. A northwest-trending fault in nearly coincident with the boundary between the two critical groundwater areas. Southwest of the fault, water levels in limestone are as...
Quality of ground water in agricultural areas of the San Luis Valley, south-central Colorado
Patrick Edelmann, David R. Buckles
1984, Water-Resources Investigations Report 83-4281
The quality of ground water in the principal agricultural areas of the San Luis Valley, south-central Colorado was evaluated using chemical analyses of water collected from 57 wells completed in the unconfined aquifer and from 25 wells completed in the confined aquifer. Ground water in both aquifers generally contains dissolved-solids...
Effects of irrigating with wastewater on ground-water quality at Fort Carson Military Reservation golf course near Colorado Springs, Colorado
Patrick Edelmann
1984, Water-Resources Investigations Report 83-4268
Fort Carson Military Reservation has used treatment wastewater for irrigation of the Fort Carson golf course since 1971. The effect of applied wastewater on groundwater quality at Fort Carson golf course was evaluated using water levels and water-quality data from 20 observation wells. The water-quality constituents analyzed included dissolved solids,...
The Water Resources Division water level recorder rental program; history and operation
S.R. Jeffers, C. R. Wagner
1984, Open-File Report 84-735
The U.S. Geological Survey introduced a new water level recorder in the early 1960 's to automate computation of streamflow records. At the same time it developed a rental program as a means of providing the recorders to field offices. This report documents the experience gained over the past 20...
Habitat Suitability Index Models and Instream Flow Suitability Curves: Warmouth
Thomas E. McMahon, Glen Gebhart, O. Eugene Maughan, Patrick C. Nelson
1984, FWS/OBS 82/10.67
The wa rmouth (Lepomi s gul osus) occurs naturally throughout the central and southeastern United States. It is distributed throughout Kansas, Iowa, and Missouri, north to southern Wisconsin, lower Michigan, Lake Erie, and western Pennsylvania, and south to Florida and west through the Gulf States to the Rio Grande (Hubbs...
Habitat Suitability Index Models: American black duck (wintering)
James C. Lewis, Russell L. Garrison
1984, FWS/OBS 82/10.68
INTRODUCTION The American black duck, commonly known as the black duck, is migratory and has a wide geographic range. American black ducks breed from Cape Hatteras, North Carolina, west to the Mississippi River and north through the eastern Canadian boreal forest (Bellrose 1976). The winter range extends from the Rio Grande...
Measured sections and discussion of the main turbidite member, Middle Pennsylvanian Minturn Formation, northern Sangre de Cristo Range, Custer and Saguache counties, Colorado
S. J. Soulliere, B.L. DeAngelis, D. A. Lindsey
1984, Miscellaneous Field Studies Map 1622-B
Turbidites are sediments deposited by turbid density currents. The turbidites described here are interpreted as prodelta deposits that formed in front of fan deltas and alluvial fans during the uplift of the ancestral Rocky Mountains in Pennsylvanian time. Laterally extensive, lenticular sand bodies deposited by turbidity flows crop out in...
Reconnaissance of water-quality characteristics of streams in the City of Charlotte and Mecklenburg County, North Carolina
W.H. Eddins, J. K. Crawford
1984, Water-Resources Investigations Report 84-4308
In 1979-81, water samples were collected from 119 sites on streams throughout the City of Charlotte and Mecklenburg County, North Carolina, and were analyzed for specific conductance, dissolved chloride, hardness, pH, total alkalinity, total phosphorus, trace elements, arsenic, cadmium, chromium, copper, iron, lead, manganese, mercury, silver, and zinc and biological...
Hydrogeologic setting east of a low-level radioactive-waste disposal site near Sheffield, Illinois
J.B. Foster, George Garklavs, G.W. Mackey
1984, Water-Resources Investigations Report 84-4183
Core samples from 45 test wells and 4 borings were used to describe the glacial geology of the area east of the low-level radioactive-waste disposal site near Sheffield, Bureau County, Illinois. Previous work has shown that shallow ground water beneath the disposal site flows east through a pebbly-sand unit of...
A modular three-dimensional finite-difference ground-water flow model
M.G. McDonald, A.W. Harbaugh
1984, Open-File Report 83-875
This report presents a finite-difference model and its associated modular computer program. The model simulates flow in three dimensions. The report includes detailed explanations of physical and mathematical concepts on which the model is based and an explanation of how those concepts were incorporated in the modular structure of the...
Cost effectiveness of the stream-gaging program in Maine; A prototype for nationwide implementation
Richard A. Fontaine, M. E. Moss, J.A. Smath, W. O. Thomas
1984, Water Supply Paper 2244
This report documents the results of a cost-effectiveness study of the stream-gaging program in Maine. Data uses and funding sources were identified for the 51 continuous stream gages currently being operated in Maine with a budget of \$211,000. Three stream gages were identified as producing data no longer sufficiently needed...
