DRAINAGE CORRELATION RESEARCH PROJECT FINAL REPORT

MONTANA'S EXPERIENCE WITH THE PROBLEMS OF GAGING AND COLLECTING METEROLOGIC AND HYDROLOGIC VARIABLES IS PRESENTED. SEVERAL EXPLORITORY STUDIES USING NEW TECHNIQUES TO ESTIMATE PEAK DISCHARGE RATES ON SMALL WATERSHEDS WERE MADE. A NEW APPROACH OF RAINFALL FREQUENCY - PEAK FLOW FREQUENCY METHOD FOR ESTIMATING PEAK DISCHARGE WAS DEVELOPED. IT CORRELATED PRECIPITATION TO STREAMFLOW FOR THAT PART OF MONTANA EAST OF THE ROCKIES. A PRELIMINARY STUDY APPLYING A PRINCIPAL COMPONENT ANALYSIS WITH VARIMAX ROTATION WAS PERFORMED FOR FIVE SMALL WATERSHEDS WITH 50 RECORDED STORM EVENTS. THE RELATIVE IMPORTANCE OF 29 INDEPENDENT VARIABLES WAS DESCRIBED AND EQUATIONS ESTIMATING VOLUMES AND PEAKS OF RUNOFF DEVELOPED. THE SOIL CONSERVATION SERVICE METHOD OF ESTIMATING FLOOD VOLUME WAS EXPLORED FOR APPLICABILITY TO RURAL WATERSHEDS. SEVERAL STOCHASTIC METHODS FOR ESTIMATING FLOOD PEAKS WERE TESTED FOR SUITABILITY TO THE SPECIFIC PROBLEMS OF MONTANA. /FHWA/
