FLOOD ROUTING THROUGH STORM DRAINS

THE RESULTS ARE PRESENTED OF AN ANALYTICAL AND EXPERIMENTAL STUDY OF UNSTEADY FREE SURFACE FLOW IN A SMOOTH CIRCULAR CONDUIT AT SUBCRITICAL SLOPES WITH LATERAL INFLOWS. THE ANALYTICAL PHASE WAS BASED ON DE SAINTVENANT EQUATIONS OF UNSTEADY FREE SURFACE FLOW WITH NUMERICAL SOLUTIONS BY THE METHOD OF CHARACTERISTICS. IN ORDER TO MINIMIZE THOSE EFFECTS NORMALLY ASSOCIATED WITH SMALL SCALE MODELS, THE EXPERIMENTAL PHASE WAS CARRIED OUT IN A 36-INCH DIAMETER STEEL PIPE OF 820-FT. IN LENGTH AND WITH THREE LATERAL CONNECTIONS. CAREFUL INVESTIGATIONS OF THE GEOMETRIC AND HYDRAULIC PARAMETERS AND INITIAL AND BOUNDARY CONDITIONS WERE MADE. ERRORS IN NUMERICAL COMPUTIATIONS AND EXPERIMENTAL OBSERVATIONS WERE ANALYZED. QUALITATIVE AND QUANTITATIVE COMPARISONS OF RESULTS FROM ANALYTICAL SOLUTI- ONS AND EXPERIMENTAL OBSERVATIONS WERE DISCUSSED. IN GENERAL THESE COMPARISONS SHOW THAT, FOR WAVE MOVEMENTS WITHOUT LATERAL INFLOWS, GOOD AGREEMENTS WERE ACHIEVED; BUT, FOR WAVE MOVEMENTS WITH LATERAL INFLOWS, ONLY MODERATE SUCCESS WAS INDICATED. /AUTHOR/
