Titre de série : Geological Survey Professional Paper, 1003 Titre : Effects of urbanization on stream flow and sediment transport in the Rock Creek and Anacostia River Basins Montgomery county, Maryland, 1962-74 Type de document : texte imprimé Auteurs : Yorke, T. H. ; Herb, W. J. Mention d'édition : United States.Government Printing Office Editeur : United States.Government Printing Office Année de publication : 1978 ISBN/ISSN/EAN : CI-09075 Note générale : This study was begun in 1962 to define urban runoff and sediment problems and was expanded in 1966 to evaluate response to sediment control practices inarea undergoing urban development. Land use/land cover varied considerably in the study sublasins, which ranged in size from 0,35 to 21,1 square mile. Three subbasins remained virtually rural, while the others underwent urban development. In 1974, urban land represented from 0 to 60 percent of the land use in the nine subbasins. Urbanization did not affect median and low flows, but did increase storm runoff and peak discharges.

Mention d'édition : U.S. Geological survey Editeur : U.S. Geological Survey Année de publication : 1985 ISBN/ISSN/EAN : CI-04987 Note générale : The document show that a heavy use of the Shcuylkill river for municipal water supplies and history of occidental spills and discharges of trace metals and organic substances have been a concern of state and local officials for many years. Next he contains analyses of water samples showed that some trace substances are associated chosely with particulate material transported by the river.

Titre de série : U.S. Geological Survey Water Supply paper, 2256-A Titre : Distribution and transport of trace substances in the Schurylkill River Bassin from Berne to Philadelphia, Pennsylvania Type de document : texte imprimé Auteurs : Staner, J. K. ; Yorke, T. H. ; Pederson, G. L. Mention d'édition : U S. Geological Survey Editeur : U S. Geological Survey Année de publication : 1985 ISBN/ISSN/EAN : CI-05056 Note générale : During the period from october 1978 to march 1981, the U. S. geological Survey assessed the river quality of the Schurykill River bassin in Pennsylvania from the headwater to th Fairmount dam at Philadelphia. Then, this report is part of Schurylkill river quality assessment. The study had three objectives : (1) to determine the distribution of trace substances in the Schurylkill river and its tributaries through analyses of streambed sediments, (2) to determine the average annual transport of trace substances including dissolved and total trace metals, from major tributaires and reaches of the river and (3) to determine the frequency with which concentrations of selected consituents exceed federal and state water quality criteria...
