Titre de série : U.S. Geological Survey Water Supply paper, 2216 Titre : Daily water and sediment discharges from selected rivers of the eastern United States : a time-series modeling approach Type de document : texte imprimé Auteurs : Fitzgerald, M. G. ; Karkinger, M. R. ; Michael, R Mention d'édition : United States Gouvernement Printing Office Editeur : United States Gouvernement Printing Office Année de publication : 14983 ISBN/ISSN/EAN : CI-05064 Note générale : Time-series models were constructed for analysis of daily runoff and sediment discharge data from selected rivers of the eastern United States. Logarithmic transformation and first order differencing of the data sets were necessary to produce second order stationary time series and remove seasonal trends. Cyclic models accounted for less than 42 percent in the sediment series. Analysis of the apparent oscillations of given frequenciers occuring in the data indicates that frequently occuring storms can account for as much as 50 percent of the variation in sediment dischange.

Titre de série : U.S. Geological Survey Water Supply paper, 2309 Titre : Quantitative assessment of the shallow ground-water flow system associated with Connetquot Brook, Long Island, New York Type de document : texte imprimé Auteurs : Prince, K. R. ; Franke, L. O. ; Reilly, T. E. Mention d'édition : United States Gouvernement Printing Office Editeur : United States Gouvernement Printing Office Année de publication : 1988 ISBN/ISSN/EAN : CI-05081 Note générale : Streamflow on Long Island is derived principally from shallow ground water that flows above the deeper regional flow system. The movement of shallow ground water was studied during 1975-82 at Connetquot Brook, an undisturbed stream in Connetquot River State Park, in south-central Long Island, New York. The investigation encompassed (1) field studies of streamflow, ground-water levels, and age of water as indicated by tritium and dissolved-oxygen concentration an (2) numerical simulation of the shallow flow system to evaluate the hydraulic factors that govern the direction of shallow ground-water flow near and beneath the stream.
