APPLICATION HYDROLOGIC AND HYDRAULIC RESEARCH TO CULVERT SELECTION IN MONTANA

A REGIONAL FREQUENCY ANALYSIS WAS PERFORMED, INVOLVING BOTH NATURAL AND SYNTHETIC STREAMFLOW RECORDS, TO ESTIMATE FLOOD MAGNTIUDE OF VARIOUS RECURBENCE INTERVALS FOR EACH OF 230 MONTANA WATERSHEDS. USING REGRESSION ANALYSIS, FLOOD PEAK PREDICTION EQUATIONS FOR THE 2, 5, 10, 25 AND 50 YEAR RECURRENCE INTERVALS WERE DEVELOPED FOR EACH OF 9 CONTIGUOUS GEOGRAPHIC REGIONS IN MONTANA. THESE EQUATIONS PREDICT THE FLOOD PEAK AS THE PRODUCT OF POWERS OF VARIOUS HYDROLOGIC WATERSHED PARAMETERS. A DETAILED DISUCSSION OF THE HYDRAULIC CONDITIONS WHICH OCCUR FOR VARIOUS TYPES OF CULVERT FLOW IS PRESENTED ALONG WITH MODERN CRITERIA AND METHODS FOR CULVERT SELECTION. THIS PUBLICATION APPEARS AS VOLUMES I AND II WITH SEPARATE PB NUMBERS AS INDICATED BELOW. /FHWA/
