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.
