FLOODS PREDICTED FROM RAINFALL FREQUENCIES

SHORT STREAMFLOW RECORDS OFTEN MAKE PREDICTING THE FREQUENCY OF FLOODS ON SMALL WATERSHEDS DIFFICULT. AS PEAK-FLOW RATES ARE RELATED TO RAINFALL, AT LEAST IN PART, A LOGICAL APPROACH IN PREDICTING FLOODS IS TO UTILIZE LONG RAINFALL RECORDS WHICH ARE OFTEN AVAILABLE. USING THIS APPROACH, A METHOD IS DEVELOPED TO PREDICT FLOODS ON SMALL MONTANA WATERSHEDS. THE METHOD USES MEAN ANNUAL FLOOD, DETERMINED FROM SHORT STREAMFLOW RECORDS, AND THREE FACTORS RELATING THE FREQUENCY DISTRIBUTION OF RAINFALL INTENSITIES TO THE FREQUENCY DISTRIBUTION OF PEAK ANNUAL FLOWS. AN EXAMPLE SHOWS HOW THE METHOD CAN BE APPLIED.
