Discharge ratings at gaging stations
E.J. Kennedy
1984, Techniques of Water-Resources Investigations 03-A10
A discharge rating is the relation of the discharge at a gaging station to stage and sometimes also to other variables. This chapter of 'Techniques of Water-Resources Investigations' describes the procedures commonly used to develop simple ratings where discharge is related only to stage and the most frequently encountered types...
Test well DO-CE 88 at Cambridge, Dorchester County, Maryland
Henry Trapp Jr., LeRoy L. Knobel, Harold Meisler, P. Patrick Leahy
1984, Water Supply Paper 2229
Test well DO-CE 88 at Cambridge, Maryland, penetrated 3,299 feet of unconsolidated Quaternary, Tertiary and Cretaceous sediments and bottomed in quartz-monzonite gneiss. The well was drilled to provide data for a study of the aquifer system of the northern Atlantic Coastal Plain. Twenty-one core samples were collected. Six sand zones...
A digital model for streamflow routing by convolution methods
W.H. Doyle Jr., H.O. Shearman, G.J. Stiltner, W.O. Krug
1984, Water-Resources Investigations Report 83-4160
U.S. Geological Survey computer model, CONROUT, for routing streamflow by unit-response convolution flow-routing techniques from an upstream channel location to a downstream channel location has been developed and documented. Calibration and verification of the flow-routing model and subsequent use of the model for simulation is also documented. Three hypothetical examples...
Magnitude and frequency of high flows of unregulated streams in Kansas
P. R. Jordan
1984, Open-File Report 84-453
Information on high-flow magnitude and frequency is needed for hydro-logic evaluation of such factors as flood-control storage and dam safety. High-flow information given in this report is for streamflows unaffected by major regulation, such as by large reservoirs. High-flow magnitude and frequency data are given for 91 streamflow-gaging stations through-out...
Ground-water models as a management tool in Florida
C. B. Hutchinson
1984, Water-Resources Investigations Report 84-4016
Highly sophisticated computer models provide powerful tools for analyzing historic data and for simulating future water levels, water movement, and water chemistry under stressed conditions throughout the ground-water system in Florida. Models that simulate the movement of heat and subsidence of land in response to aquifer pumping also have potential...
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...
The effect of eustatic sea-level changes on saltwater-freshwater relations in the northern Atlantic Coastal Plain
Harold Meisler, P. Patrick Leahy, LeRoy L. Knobel
1984, Water Supply Paper 2255
A finite-difference computer model was used to analyze the effect of eustatic sea-level changes on the development of the transition zone between fresh ground water and underlying saltwater in the northern Atlantic Coastal Plain. The model simulates, in cross section, the sedimentary wedge from the Delaware River estuary in New...
Potential ground-water level changes in the Mississippi River alluvial aquifer in response to proposed navigation improvements on the Yazoo River in Mississippi
A. G. Lamonds, J. M. Kernodle
1984, Water-Resources Investigations Report 84-4039
A proposed navigation project on the Yazoo River between Vicksburg and Greenwood, Mississippi, will increase minimum river stages by more than 19 feet at the site of the proposed lock and dam near Vicksburg, and will decrease minimum river stages by 2 to 7 feet in much of the upper...
Time-of-travel data for Nebraska streams, 1968 to 1977
L. R. Petri
1984, Open-File Report 84-602
This report documents the results of 10 time-of-travel studies, using ' dye-tracer ' methods, conducted on five streams in Nebraska during the period 1968 to 1977. Streams involved in the studies were the North Platte, North Loup, Elkhorn, and Big Blue Rivers and Salt Creek. Rhodamine WT dye in a...
Nutrient and detritus transport in the Apalachicola River, Florida
Harold C. Mattraw, John F. Elder
1984, Water Supply Paper 2196-C
The Apalachicola River in northwest Florida flows 172 kilometers southward from Jim Woodruff Dam near the Florida-Georgia border to Apalachicola Bay on the Gulf of Mexico. The basin is composed of two 3,100-squarekilometer subbasins, the Chipola and the Apalachicola. The Apalachicola subbasin includes a 454-square-kilometer bottom-land hardwood flood plain that...
Cost-effectiveness of the stream-gaging program in Alaska
R. D. Lamke
1984, Water-Resources Investigations Report 84-4096
This report documents the results of a study of the cost-effectiveness of the stream-gaging program in Alaska. Data uses and funding sources were identified for the 110 continuous stream-gaging stations that were being operated in September 1983 with a budget of about $1,700,000 per year.However, for the purposes of the...
Compilation of ground water quality data in Pennsylvania
J. L. Barker
1984, Open-File Report 84-706
The U.S. Geological Survey's water quality file of 4,671 wells and springs in Pennsylvania provided ground-water-quality data for Pennsylvania. The data were assembled into computer-readable format and sorted into 15 major aquifer groups based on principal lithology, physiographic province, and age. Nineteen variables in each group were summarized by the...
Ground-water resources of the White River basin, Randolph County, Indiana
W.W. Lapham, L. D. Arihood
1984, Water-Resources Investigations Report 83-4267
The two major aquifer systems in Randolph County, Indiana are sand and gravel and bedrock (limestone, dolomite, and shale of Silurian to Odovician age). The average thickness of the sands and gravels is 15 ft, and the aquifers are areally discontinuous. The bedrock aquifer underlies the entire study area and...

Vertical crustal movements in Southern California, 1974 to 1978
Robert O. Burford, Thomas D. Gilmore
1984, Circular 905
An extensive resurvey of most of the first-order leveling network in southern California, known as the Southern California Releveling Program (SCRP), was carried out during the first 5 months of 1978. The primary scientific purpose of these measurements was to rapidly update the vertical control record throughout a recently uplifted...
