Potential hazards from future eruptions in the vicinity of Mount Shasta Volcano, Northern California
C. Dan Miller
1980, Bulletin 1503
Mount Shasta has erupted, on the average, at least once per 800 years during the last 10,000 years, and about once per 600 years during the last 4,500 years. The last known eruption occurred about 200 radiocarbon years ago. Eruptions during the last 10,000 years produced lava flows and domes...

Recent eruptive history of Mount Hood, Oregon, and potential hazards from future eruptions
Dwight Raymond Crandell
1980, Bulletin 1492
Each of three major eruptive periods at Mount Hood (12,000-15,000(?), 1,500-1,800, and 200-300 years ago) produced dacite domes, pyroclastic flows, and mudflows, but virtually no pumice. Most of the fine lithic ash that mantles the slopes of the volcano and the adjacent mountains fell from ash clouds that accompanied the...
Water-quality monitoring of three major tributaries to the Chesapeake Bay: Interim data report
David J. Lang, David Grason
1980, Water-Resources Investigations Report 80-78
The U.S. Geological Survey is monitoring the water quality of three major tributaries to Chesapeake Bay at their fall lines to obtain estimates of constituent inputs potentially available to the bay. The monitoring sites are: Susquehanna River at Conowingo, Md.; Potomac River at Washington, D.C.; and James River at Cartersville,...
Evaluation of peak-flow data network of small streams in Missouri
Leland D. Hauth
1980, Water-Resources Investigations Report 80-87
Standard regression models were used as a tool to evaluate the transferability of streamflow characteristics for the small-streams network in Missouri. Station records were divided into segments and tested for adequacy of record length and sample size for two physiographic regions. The standard error of estimate for each calibrated regression...
Estimated water use in Florida, 1977
Stanley D. Leach, Henry G. Healy
1980, Water-Resources Investigations Report 79-112
During 1977, an average of 21,466 million gallons of water was withdrawn daily for use in Florida--an increase of 6,153 million gallons per day since 1970. The 1977 daily use was 14,812 million gallons of saline water and 6,654 million gallons of freshwater. Most of the saline water, largely surface...
Distribution of nitrate in the unsaturated zone, Highland-East Highlands area, San Bernardino County, California
John M. Klein, Wesley L. Bradford
1980, Water-Resources Investigations Report 80-48
Nitrogen in the unsaturated soil zone in the Highland-East Highlands area of San Bernardino County, Calif., has been suspected as the source of nitrate in water from wells. Plans to recharge the local aquifers with imported surface water would raise the water table and intercept that nitrogen. This study was...
Data-base system for northern Midwest regional aquifer-system analysis
A.L. Kontis, Richard J. Mandle
1980, Water-Resources Investigations Report 80-104
The U.S. Geological Survey is conducting a study of the Cambrian and Ordovician aquifer system of the northern Midwest as part of a national series of Regional Aquifer-Systems Analysis (RASA). An integral part of this study will be a simulation of the ground-water flow regime using the Geological Survey's three-dimensional...
Calibration of a distributed routing rainfall-runoff model at four urban sites near Miami, Florida
W. Harry Doyle Jr., Jeffrey E. Miller
1980, Water-Resources Investigations Report 80-1
Urban stormwater data from four Miami, Fla. catchments were collected and compiled by the U.S. Geological Survey and were used for testing the applicability of deterministic modeling for characterizing stormwater flows from small land-use areas. A description of model calibration and verification is presented for: (1) A 40.8 acre single-family...
Hydrology and model study of the proposed Prosperity Reservoir, Center Creek Basin, southwestern Missouri
Edward Joseph Harvey, Leo F. Emmett
1980, Water-Resources Investigations Report 80-7
A dam and reservoir have been proposed for construction on Center Creek, Jasper County, in southwestern Missouri. Ground-water levels in the hills adjacent to the reservoir will rise when the impoundment is completed. One of the problems is that the proposed site of Prosperity Reservoir is a few miles upstream...
Methods and applications of digital-model simulation of the Red River alluvial aquifer: Shreveport to the mouth of the Black River, Louisiana
A. H. Ludwig, J. E. Terry
1980, Water-Resources Investigations Report 79-114
The Red River Waterways Project provides for the construction of five locks and dams on the Red River from the Mississippi River to Shreveport, La. The methodology used by the U.S. Geological Survey in studying the effects of the navigation pools on the ground-water-flow regime involved digital modeling of steady-...

A technique for estimating flood heights on small streams in the city of Charlotte and Mecklenburg County, North Carolina
William H. Eddins, N.M. Jackson Jr.
1980, Water-Resources Investigations Report 80-106
A method for estimating the height reached by floods having recurrence intervals of 10, 20, and 100 years is defined for unregulated streams in Charlotte and Mecklenburg County draining areas of less than 1.0 square mile. Flood heights, defined as the vertical distance between the streambed at riffles and the...
A limnological study of 43 selected Maine lakes
Derrill J. Cowing, Matthew Scott
1980, Water-Resources Investigations Report 80-69
Federal and State legislation require the trophic classification of lakes and ponds in the State of Maine as part of a lake management program. In 1974, the State of Maine Department of Environmental Protection (DEP) adopted a preliminary set of procedures for establishing an index of lake trophic status. Also...
Water quality of the Neuse River, North Carolina: Variability, pollution loads, and long-term trends
Douglas A. Harned
1980, Water-Resources Investigations Report 80-36
A water-quality study of the Neuse River, N.C., based on data collected during 1956-77 at the U.S. Geological Survey stations at Clayton and Kinston, employs statistical trend analysis techniques that provide a framework for river quality assessment. Overall, water-quality of the Neuse River is satisfactory for most uses. At Clayton,...
Using channel geometry to estimate flood flow at ungaged sites in Idaho
W. A. Harenberg
1980, Water-Resources Investigations Report 80-32
Measurements at bankfull stage were made at 136 sites to determine whether predictions of flood discharges using channel-geometry characteristics are as good as or better than predictions using basin characteristics. These measurements are used to determine the variables of bankfull width, area, depth, and velocity. These variables are combined with...
Geology and ground water in north-central Santa Cruz County, California
Michael J. Johnson
1980, Water-Resources Investigations Report 80-26
North-central Santa Cruz County is underlain mainly by folded sedimentary rocks of Tertiary and Cretaceous age that have been highly fractured by movements in the San Andreas fault system. Ground water is stored in fractures within shale and mudstone formations and in intergranular pore spaces within fine- to very fine-grained...
Geothermal gradients in the Missoula and Bitterroot Valleys, west-central Montana
Robert B. Leonard, Wayne A. Wood
1980, Water-Resources Investigations Report 80-89
Temperature-depth profiles of six cased test holes in the Missoula and Bitterroot Valleys, west-central Montana, consist of linear segments, the intersections of which commonly correspond with lithologic boundaries. Geothermal gradients commonly decreased with depth, probably as a result of compaction and higher quartz content of the deeper sedimentary deposits. There...
Calibration and testing of selected portable flowmeters for use on large irrigation systems
Richard R. Luckey, Frederick J. Heimes, Neville G. Gaggiani
1980, Water-Resources Investigations Report 80-72
Existing methods for measuring discharge of irrigation systems in the High Plains region are not suitable to provide the pumpage data required by the High Plains Regional Aquifer System Analysis. Three portable flowmeters that might be suitable for obtaining fast and accurate discharge measure-ments on large irrigation systems were tested...
