Flood of November 1985 in West Virginia, Pennsylvania, Maryland, and Virginia

Rainfall in excess of 10 inches occurred during the first 5 days of November 1985, resulting in devastating flooding in the Mid-Atlantic states of West Virginia, Pennsylvania, Maryland, and Virginia. Throughout the area, many streams exceeded previously known flood heights and discharges and, in many cases, the recurrence interval of peak discharges exceeded 100 years. The peak stage and discha

Techniques for estimating streamflow characteristics in the Eastern and Interior coal provinces of the United States

Techniques are presented for estimating various streamflow characteristics, such as peak flows, mean monthly and annual flows, flow durations, and flow volumes, at ungaged sites on unregulated streams in the Eastern Coal region. Streamflow data and basin characteristics for 629 gaging stations were used to develop multiple-linear-regression equations. Separate equations were developed for the East

Ground-water recharge and its effects on nitrate concentration beneath a manured field site in Pennsylvania

Ground-water recharge to a shallow, unconfined, fractured dolomite aquifer underlying agricultural land in Lancaster County, Pennyslvania occurs by two mechanisms. Direct recharge occurs through pathways such as near-surface bedrock fractures and sinkholes, and affects dissolved nitrate concentration of ground water within two to three days; its effects last only about one week. Gradual recharge o

Effects of surface coal mining on suspended-sediment discharge in a small mountain watershed, Fayette County, Pennsylvania

Data collected in the upper Stony Fork basin from July 1980 to November 1981 indicate that logging operations associated with block-cut surface mining temporarily increased suspended-sediment discharge of Stony Fork. However, the strip-mining operation did not increase the suspended sediment discharges of Stony Fork because of effective sediment-control measures. These controls included diversion

Areal and temporal variability of selected water-quality characteristics in two hydrologic-benchmark basins in the northeastern United States

Two U.S. Geological Survey National Hydrologic Benchmark stations--Young Womans Creek near Renovo, Pennsylvania and Esopus Creek at Shandaken, New York--were studied to (1) define, both areally and temporally, variations of stream acidity and other water quality characteristics within the basins; (2) evaluate how well the data collected at the Benchmark station represent the water quality conditio

Results of a preimpoundment water-quality study of Swatara Creek, Pennsylvania

The water quality of Swatara Creek prior to impoundment by the proposed Swatara Creek Reservoir in south-central Pennsylvania was studied from July 1981 through October 1982. The report, done in cooperation with the Pennsylvania Department of Environmental Resources (PaDER), Bureau of State Parks, presents information on existing water-quality conditions. A discussion of possible water-quality con

Occurrence of nitrate and herbicides in ground water in the upper Conestoga River basin, Pennsylvania : water-quality study of the Conestoga River headwaters, Pennsylvania

Nitrate-nitrogen and herbicide ground-water data is being collected by the u.s. Geological Survey as part of the nationwide Rural Clean Water Program designed to determine the effects of agricultural-management practices on water quality. Data collected from September 1982 to October 1983 · in the 188-square mile intensively farmed upper Conestoga River basin indicates high nitrate and detectable

Temporal changes in sulfate, chloride, and sodium concentrations in four eastern Pennsylvania streams

Trend analyses of 20 years or more of chemical quality and streamflow data for four streams in eastern Pennsylvania indicate that sulfate has decreased significantly in three of the four basins studied, while sodium and chloride have generally increased. The majority of chemical quality changes occurred in the late 1950 's and early 1960 's coincident with significant cultural changes. It is belie

Statistical analyses of flood frequency, low-flow frequency, and flow duration of streams in the Philadelphia Area, Pennsylvania

Flood frequency, low-flow frequency, and flow-duration characteristics were computed for 26 stream-gaging stations in and near Philadelphia. Data were obtained from 21 continuous-recording stations and five stations that were initially continuous-recording stations, but which were subsequently converted to crest-stage stations. The annual peak flows were fitted to the three-parameter log-Pearson T

Temperature of ground water at Philadelphia, Pennsylvania, 1979- 1981

Anthropogenic heat production has undoubtedly caused increased ground-water temperatures in many parts of Philadelphia, Pennsylvania, as shown by temperatures of 98 samples and logs of 40 wells measured during 1979-81. Most sample temperatures were higher than 12.6 degrees Celsius (the local mean annual air temperature), and many logs depict cooling trends with depth (anomalous gradients). Heating
