WHERE IS URBAN HYDROLOGY PRACTICE TODAY?

THE EVOLUTION OF URBAN STREET CONSTRUCTION AND ITS EFFECTS UPON URBAN DRAINAGE ARE TRACED. RATIONAL METHOD DEVELOPMENT AND INCONSISTENCIES IN ITS APPLICATION ARE SUMMARIZED. THE EMPHASIS IS ON LACK OF ABSOLUTE PRECIPITATION DATA WITH RESULTANT INHIBITING EFFECTS UPON DEVELOPMENT OF IMPROVED RUNOFF PREDICTION METHODS. TWO DRAINAGE SYSTEMS ON EACH URBAN DRAINAGE AREA WOULD REDUCE DRAINAGE COSTS, REDUCE FLOODING LOSSES, AND ENHANCE PROPERTY VALUES, STABILIZE NEIGHBORHOODS, AND IMPROVE URBAN LIFE QUALITY. SOME BASIC METHODS FOR MANAGING URBAN RUNOFF ARE ALSO INDICATED TO ATTENUATE PEAK FLOWS. A LOW MAINTENANCE CHANNEL IS IDENTIFIED AS BEING MORE REALISTIC THAN USUAL URBAN CHANNEL DESIGNS. DIRECT LOSSES FROM AND EXPENDITURES FOR URBAN DRAINAGE APPROXIMATE FOUR BILLION DOLLARS PER YEAR. THE NATION COULD REALIZE DISPROPORTIONATELY GREAT RETURNS FROM URBAN HYDROLOGY RESEARCH. /AUTHOR/
