Evaluation of a watershed model to simulate sediment transport in a small agricultural watershed in Indiana
L. D. Arihood
1989, Water-Resources Investigations Report 88-4222
The streamflow and sediment components of the watershed model, ' Hydrologic Simulation Program-Fortran ', were evaluated using 2 years and 9 months of data from a 2.7-sq mi agricultural watershed in Indiana. Hydrographs of simulated sediment concentration generally have smaller peaks and longer recessions than do hydrographs of measured data....
Hydrology of the Mississippi River Valley alluvial aquifer, south- central United States — A preliminary assessment of the regional flow system
D. J. Ackerman
1989, Water-Resources Investigations Report 88-4028
Data describing the aquifer framework and steady-state regional flow were assembled for the Mississippi River Valley alluvial aquifer north of Vicksburg, Mississippi. The aquifer is part of the Mississippi embayment aquifer system. The 60 to 140 ft thick alluvial aquifer grades from gravel at the bottom to fine sand near...
Water resources of Sedgwick County, Kansas
H.E. Bevans
1989, Water-Resources Investigations Report 88-4225
Hydrologic data from streams, impoundments, and wells are interpreted to: (1) document water resources characteristics; (2) describe causes and extent of changes in water resources characteristics; and (3) evaluate water resources as sources of supply. During 1985, about 134,200 acre-ft of water (84% groundwater) were used for public (42%), irrigation,...
Bibliography of Oklahoma hydrology; reports prepared by the U.S. Geological Survey and principal cooperating agencies, 1901-88

Reports on the hydrology of Oklahoma have been issued by the U.S. Geological Survey since 1901. This bibliography lists reports on hydrology in Oklahoma prepared by the U.S. Geological Survey and the principal State cooperating agencies, the Oklahoma Geological Survey and the Oklahoma Water Resources Board. Of the nearly 350...
Hydrologic and geochemical monitoring in Long Valley caldera, Mono County, California, 1986
C. D. Farrar, M.L. Sorey, S.A. Rojstaczer, A.C. Steinemann, M. D. Clark
1989, Water-Resources Investigations Report 89-4033
The U.S. Geological Survey continued to monitor hydrologic and geochemical conditions in the Long Valley caldera during 1986. The monitoring is directed toward detecting changes in the hydrologic system caused by tectonic or magmatic processes. Data collected during 1986 include chemical and isotopic composition of water from selected streams sites,...
Suspended-sediment yields from an unmined area and from mined areas before and after reclamation in Pennsylvania, June 1978-September 1983
L.A. Reed, R.A. Hainly
1989, Water-Resources Investigations Report 88-4005
The U.S. Geological Survey, in cooperation with the Pennsylvania Department of Environmental Resources, has collected hydrologic data from areas in Tioga, Clearfield, and Fayette Counties to determine the effects of surface coal mining on sediment yields. The data were collected from June 1978 through September 1983. Rainfall, streamflow and suspended-sediment...
Cost-effectiveness of the stream-gaging program in Kentucky
K.J. Ruhl
1989, Water-Resources Investigations Report 89-4067
This report documents the results of a study of the cost-effectiveness of the stream-gaging program in Kentucky. The total surface-water program includes 97 daily-discharge stations , 12 stage-only stations, and 35 crest-stage stations and is operated on a budget of $950,700. One station used for research lacks adequate source of...
Physical and chemical data from two water-quality surveys of streams in the Lewisville Lake watershed, north-central Texas, 1984 and 1985
W. Scott Gain
1989, Open-File Report 89-258
Physical and chemical water-quality data and nitrogen and phosphorus yields for 29 sites sampled in two synoptic surveys of streams within the Lewisville Lake watershed are presented in this report. The two synoptic surveys were conducted in March 1984 and March 1985, as a reconnaissance and assessment of water quality...
Flow characteristics of the Clearwater River and tributaries from Clearbrook to Plummer, northwestern Minnesota
G. A. Payne
1989, Water-Resources Investigations Report 89-4045
During March through October 1986, 52,560 acre-feet of water passed the continuous-record stream gaging station on the Clearwater River near Clearbrook, Minnesota, 4.8 river miles upstream from the Red Lake Indian Reservation. Flow at the downstream boundary of the Reservation totaled 93,770 acre-feet. The increase in Clearwater River flow in...
Hydrology of the Oakley Fan Area, south-central Idaho
H.W. Young, G. D. Newton
1989, Water-Resources Investigations Report 88-4065
The Oakley Fan area is a broad, crescent-shaped lowland along the southern margin of the Snake River Plain in south-central Idaho. Intensive groundwater development for irrigation has resulted in rapid water-level declines and, as a consequence, designation by the State of four Critical Groundwater Areas. Principal aquifers are in limestone,...
Description of data files compiled for the Central Midwest Regional Aquifer-System Analysis
John O. Helgesen, Cristi V. Hansen
1989, Open-File Report 89-42
Several types of geologic and hydrologic data were collected and compiled as part of the Central Midwest Regional Aquifer-System Analysis. The study described the hydrology of Cambrian-age through Cretaceous-age rocks in all of Kansas and Nebraska and parts of eight other states. Information from both water wells and petroleum wells...
Summary of the U.S. Geological Survey and U.S. Bureau of Land Management national coal-hydrology program, 1974-84
L. J. Britton, C. L. Anderson, D. A. Goolsby, B. P. VanHaveren, editor(s)
1989, Professional Paper 1464
During the decade 1974-84, the U.S. Geological Survey and the U.S. Bureau of Land Management cooperated on investigations to collect information and to study hydrologic processes related to development and mining of federally owned coal. In addition, the U.S. Geological Survey conducted similar investigations related to nonfederally owned coal. As...

Methods for estimating monthly streamflow characteristics at ungaged sites in western Montana
Charles Parrett, Kenn D. Cartier
1989, Open-File Report 89-40
Three methods were developed for estimating monthly streamflow characteristics for western Montana. The first method, based on multiple-regression equations, relates monthly streamflow characteristics to various basin and climatic variables. Standard errors range from 43 to 107%. The equations are generally not applicable to streams that receive or lose water as...
