Techniques for estimating magnitude and frequency of floods on streams in Indiana
Equations are presented for estimating the magnitude and frequency of floods at ungaged sites on unregulated and nonurban streams in Indiana. The equations were developed by multiple-regression, analysis of basin characteristics and peak-flow statistical data from 242 gaged locations in Indiana, Ohio, and Illinois. The State of Indiana was divided into seven areas on the basis of the regression an

Floods of March 1982, Indiana, Michigan, and Ohio
Rapid melting of a snowpack containing 2 to 6 inches of water equivalent coinciding with moderate rainfall caused flooding in March 1982 across northern Indiana, southern Michigan, and northwestern Ohio. Millions of dollars in property damage and the loss of four lives resulted from the flooding. Peak discharges at several gaging stations in each of the following river basins have recurrence inter

Evaluation of the ground-water resources of parts of Lancaster and Berks Counties, Pennsylvania
Secondary openings in bedrock are the avenues for virtually all ground-water flow in a 626-sqare-mile area in Lancaster and Berks Counties, Pennsylvania. The number, size, and interconnection of secondary openings are functions of lithology, depth, and topography. Ground water actively circulates to depths of 150 to 300 feet below land surface. Total average annual ground-water recharge for the ar

Water-quality and chemical loads of the Susquehanna River at Harrisburg, Pennsylvania, April 1980 to March 1981
Water samples were analyzed for 42 chemical constituents to determine the water quality of the Susquehanna River at Harrisburg, Pennsylvania from April 1, 1980, to March 31, 1981. The investigation was part of the U.S. Environmental Protection Agency's (EPA) Chesapeake Bay Program's Fall Line Monitoring Project to provide information on the Susquehanna River's freshwater input to the Chesapeake Ba

Hydrologic data for aquifers in Philadelphia, Pennsylvania
Selected data on the ground-water resources of Philadelphia, Pennsylvania, are presented in this report. Information including water levels and data on aquifers is tabulated for 828 wells and 3 sumps. Chemical analyses are given for 1,467 water samples obtained from 205 sites and include 103 analyses for trace elements and 68 analyses for volatile organic compounds. An index of geophysical logs in

International strategic minerals inventory summary report; chromium
Major world resources of chromium, a strategic mineral commodity, are described in this summary report of information in the International Strategic Minerals Inventory {ISMI}. ISMI is a cooperative data-collection effort of earth-science and mineral-resource agencies in Australia, Canada, the Federal Republic of Germany, the Republic of South Africa, and the United States of America. This report,

The Nisqually Glacier, Mount Rainier, Washington, 1857-1979: A summary of the long-term observations and a comprehensive bibliography
Nisqually Glacier on Mount Ranier, Washington has a long record of terminus position observations and ice-surface altitude measurements along specific profiles, and has been the topic of numerous scientific studies. From the earliest observations in 1857 to the present many individuals and several different organizations have been involved in data collection at Nisqually Glacier. In order to prese

Flow routing in the Susquehanna River basin: Part V – Flow-routing models for the West Branch Susquehanna River basin, Pennsylvania
Digital-computer, daily-flow routing models were developed for four consecutive reaches of the West Branch Susquehanna River between Curwensville and Lewisburg, Pennsylvania. These models will enable water-resources managers to evaluate efficiently the effect of present and future water-resources developments on streamflows at six locations along the West Branch Susquehanna River. The models utili

Florida: A Jurassic transform plate boundary
Magnetic, gravity, seismic, and deep drill hole data integrated with plate tectonic reconstructions substantiate the existence of a transform plate boundary across southern Florida during the Jurassic. On the basis of this integrated suite of data the pre-Cretaceous Florida-Bahamas region can be divided into the pre-Jurassic North American plate, Jurassic marginal rift basins, and a broad Jurassic

Ferromanganese micronodules from the surficial sediments of Georges Bank
Ferromanganese micronodules have been found on Georges Bank, off the U.S. northeast coast, distributed throughout the surficial sediments within an area about 125 km long and at least 12 km wide. These coarse, sand-sized concretions have precipitated from metal-rich interstitial waters and contain many of the textural and structural features common to other neritic nodules. Most of the nodules hav

Slope-stability analysis and creep susceptibility of Quaternary sediments on the northeastern United States continental slope
The continental slope off the northeastern United States is a relatively steep, morphologically complex surface which shows abundant evidence of submarine slides and related processes. Because this area may be developed by the petroleum industry, questions arise concerning the potential for further slope failures or unacceptable deformations and the conditions necessary to cause such instabilities
