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 Type III distribution to develop the flood- frequency characteristics. The range of the reported annual recurrence intervals for flood-frequency depends on record length. Low-flow frequency characteristics for various numbers of consecutive days were also defined by fitting data to the log-Pearson Type III distribution. Standard analyses of daily discharges produced the duration curve characteristics. Results of these analyses are tabulated.

Water resources data, Pennsylvania water year 1982. Volume 1: Delaware River basin

Water resources data for the 1982 water year for Pennsylvania consist of records of discharge and water quality of streams; elevation and contents of lakes and reservoirs; and elevation of tides; and water levels of ground-water wells. This volume contains records for water discharge at 66 gaging stations; elevation and contents at 11 lakes and reservoirs; elevation of tides at 1 gaging station; water quality at 33 gaging stations; and water levels at 16 observation wells. Also included are data for 34 crest-stage, 80 low-flow, and 43 water-quality partial-record stations. Locations of these sites are shown on figures 6 through 9. Additional water data were collected at various sites not involved in the systematic data-collection program and are published as miscellaneous measurements and analyses. These data together with the data in Volume 2 and 3 represent that part of the National Water Data System operated by the U.S. Geological Survey and cooperating State, local and Federal agencies in Pennsylvania.

Time-of-travel studies, Susquehanna River, Binghamton, New York, to Clarks Ferry, Pennsylvania

Results of time-of-travel studies are presented in both tabular and graphical form for several flow conditions in the Susquehanna River from Binghamton, N.Y., to Clarks Ferry, Pa. This reach is approximately 240 miles (386 kilometres) long, measured along the center of the channel, and has a drainage area of about 19,700 square miles (51,000 square kilometres) at its downstream end. A solution of Rhodamine BA, a fluorescent dye, was injected into the river at selected sites. Water samples were collected throughout the study reach and were analyzed, by use of a fluorometer, for dye concentration. Time-of-travel data have been related to stream discharge and to distance along the river channel. These relations permit the estimation of travel time for a water-soluble contaminant moving between any two points within the study reach at any desired discharge in the lower-to- medium flow range. The range of discharge for these studies was from 1,560 ft3/s (44.2 m3/s) to 4,330 ft3/s (123 m3/s) at the Wilkes-Barre, Pa. gaging station. The recorded travel times for the typical subreach, Shickshinny, Pa. to Danville 'Pa., ranged from 72.5 hours to 36.7 hours.

Map showing flood of June 1972 resulting from tropical storm Agnes, Bald Eagle and Fishing Creeks at Mill Hall, Pennsylvania

In June 1972, tropical storm Agnes caused severe flooding in Pennsylvania and southern New York. The floods on many major streams were the highest known since the river valleys were settled. Maximum discharges were as much as twice the discharge of a 50-year flood. In central Pennsylvania, large areas in Lock Haven, Mill Hall, Wilkes-Barre, Kingston, Pittston, Harrisburg, and in many smaller communities were inundated to depths of several feet. The extent of flooding shown on the map was delineated by the U.S. Geological Survey from field surveys made soon after the flood.
