Estimates of these flood events are used by the Federal, State, regional, and local officials to safely and economically design hydraulic structures as well as for effective floodplain management. The regression relationships developed to predict flows at ungauged sites do not always hold true for steep slope watersheds in New England. This study developed the regression relationships to predict peak flows for ungaged, unregulated steep streams in New England with recurrence intervals of 2, 5, 10, 25, 50, 100, and 500 years. For watersheds having a main channel slope that exceeds 50 ft per mile, peak flows are well estimated by the watershed drainage area and the mean annual precipitation. For these steep watersheds, the series of regression equations was found to perform as well or better than the individual state regression equations.
