Sediment transport by streams draining into the Delaware Estuary 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...

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

Role of water in urban planning and management Role of water in urban planning and management

Concentrations of people in urban areas intensify water problems such as flooding and pollution, but these deleterious effects on water resources can be minimized or corrected by comprehensive planning and management. Such planning of the water resources of an urban area must be based on adequate hydrologic data. Through the use of a matrix, urban water problems can be evaluated and...

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

Water facts and figures for planners and managers Water facts and figures for planners and managers

Water is defined in terms of its chemical composition and dominant physical properties, such as expansion on freezing and high surface tension. Water on the earth is about 97 percent in the seas, 2 percent in glacier ice, principally Greenland and Antarctica. Man is left with less than 1 percent as liquid fresh water to sustain his needs. This is possible under good management because...

Flood of September 1971 in southeastern Pennsylvania 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...

Appraisal of stream sedimentation in the Susquehanna River basin Appraisal of stream sedimentation in the Susquehanna River basin

The Susquehanna River presently transports about 3.0 million tons of sediment annually (110 tons per square mile). Only about 1.8 million tons of sediment enters the head of Chesapeake Bay annually because some sediment is trapped behind the power dams on the lower Susquehanna. Measured annual sediment yields from subbasins in the Susquehanna range from 40 to 440 tons per square mile...

Water quality of streams in the Neshaminy Creek basin, Pennsylvania Water quality of streams in the Neshaminy Creek basin, Pennsylvania

The Neshaminy has carved a scenic route on its way to the Delaware River, thereby helping to increase the value of land. The unabated growth of nearby metropolitan areas and the multiplying needs for water and open space for water storage and recreation in southeastern Pennsylvania have become impelling forces that mark the Neshaminy valley watershed for continued development of its land...
