A COMPARISON OF METHODS FOR ESTIMATING FLOOD PEAKS ON STREAMS IN MASSACHUSETTS

Modifications of the Potter method (Potter, 1957) and the Small Basin Study (SBS) method (Johnson and Tasker, 1974) for estimating flood peaks from basin characteristics are used to predict the 50- and 10-6314 peak discharges at 77 continuous and partial-record gaging stations in Massachusetts. The predicted peaks made by each method are compared with the peak discharge estimated from station frequency curves for each station. Results indicate that, while the random error for both methods is about the same, the modified Potter method systematically predicts peaks which are substantially higher (150 percent than those estimated from station frequency curves. /AUTHOR/
