Hydrology of the abandoned coal mines in the Wyoming Valley, Pennsylvania

Mine-water discharge, into the Susquehanna River degrades the river's quality during periods of low flow to a point critical for subsistence of aquatic life. To determine what measures are required to provide a better quality mine-water discharge in the Wyoming Valley, mine hydrology and mine-water quality are related to mine-pool management. The addition of mine-pool outlets at several locations

Water demands for expanding energy development

Water is used in producing energy for mining and reclamation of mined lands, onsite processing, transportation, refining, and conversion of fuels to other forms of energy. In the East, South, Midwest, and along the seacoasts, most water problems are related to pollution rather than to water supply. West of about the 100th meridian, however, runoff is generally less than potential diversions, and e

Large rivers of the United States

Information on the flow of the 28 largest rivers in the United States is presented for the base periods 1931-60 and 1941-70. Drainage area, stream length, source, and mouth are included. Table 1 shows the average discharge at downstream gaging stations. Table 2 lists large rivers in order of average discharge at the mouth, based on the period 1941-70.

Dissolved-solids discharge to the oceans from the conterminous United States

Dissolved-solids data from 54 river basins for 1966-69 were used to compute the amount of dissolved material contributed to the oceans from the conterminous United States. The computations show that about 264,000,000 tons are discharged annually. The Gulf of Mexico receives the largest load, about 183,000,000 tons, of which about 157,000,000 tons are contributed by the Mississippi River. The Atlan

Extent and development of urban flood plains

A study of26 urbanized areas in the United States indicates that the amount of urban area in flood plains ranges from 2.4 percent for Spokane, Wash., to 81 percent for Monroe, La. The median value is 10.5 percent, and the weighted average is 16.2 percent. The amount of development on these flood plains also varies widely, from 11.3 percent for Lorain-Elyria, Ohio, to 97 percent for Great Falls, Mo

Sediment transport by streams draining into the Delaware Estuary

The quantity of sediment transported by streams draining into the Delaware estuary from Pennsylvania, New Jersey, and Delaware varies areally according to geology, physiography, and land use. Of the estimated total sediment load of 1.6 million tons entering the Delaware estuary annually, about 48 percent is contributed by the Delaware River main stem at Trenton, NJ; 34 percent by Pennsylvania trib

Flood of September 1971 in southeastern Pennsylvania

Record-breaking floods on Sept. 13, 1971, occurred in some urbanized basins of southeastern Pennsylvania. This flooding resulted from heavy, intermittent thunderstorms on Sept. 11-13, 1971, which produced 8 to 12 inches of rainfall in the basins of Skippack, Stony, and Chester Creeks. Rain was heaviest during mid-day of the 13th. Damage to homes, businesses, and public property amounted to many mi

Extent and frequency of floods on the Schuylkill River near Phoenixville and Pottstown, Pennsylvania

Knowledge of the frequency and extent of flooding is an important requirement for the design of all works of man bordering or encroaching on flood plains. The proper design of bridges, culverts, dams, highways, levees, reservoirs, sewage-disposal systems, waterworks and all structures on the flood plains of streams requires careful consideration of flood hazards. -1- By use of relations presented

Fluvial-sediment discharge to the oceans from the conterminous United States

This report is a contribution to the UNESCO-sponsored project of the International Hydrological Decade called the World Water Balance. Annual fluvial-sediment discharge from the conterminous United States averages 491,449,600 short tons, of which 14,204,000 is discharged to the Atlantic Ocean, 378,179,000 to the Gulf of Mexico, and 99,066,600 to the Pacific Ocean. Data from 27 drainage areas were
