AN ECONOMIC STUDY OF URBAN AND HIGHWAY DRAINAGE SYSTEMS

URBAN AND HIGHWAY DRAINAGE SYSTEMS ARE DESIGNED TO CONTROL FLOODING, BUT LITTLE HAS BEEN DONE IN THE PAST TO ASSESS POTENTIAL FLOOD DAMAGES OR TO DEVELOP METHODS FOR BALANCING THE COST OF PROTECTIVE WORKS AND RESIDUAL FLOOD DAMAGES. CHARACTERISTICS OF FLOOD LOSSES ARE INVESTIGATED IN THIS STUDY. INFORMATION COLLECTED ON THE COST OF DRAINAGE FACILITIES AND DAMAGES IN URBAN AREAS IS ANALYZED. FOR HIGHWAY DRAINAGE, INTERRUPTION OF TRAFFIC FLOW IS INTERPRETED AS A MAJOR FLOOD DAMAGE. MATHEMATICAL MODELS ARE DEVELOPED FOR THE SOLUTION OF SPECIFIC DRAINAGE PROBLEMS. SIMULATION IS USED TO DESCRIBE THE RANDOM EFFECTS OF RUNOFF AND TRAFFIC IN A MODEL FOR SELECTING PUMPING FACILITIES TO REMOVE STORM WATER AT A HIGHWAY UNDERPASS. TWO MODELS FOR FINDING THE OPTIMUM SPACING OF INLETS ARE DEVELOPED AND SOLVED. SENSITIVITY OF THE MODELS IS INVESTIGATED TO DETERMINE AND RELATIVE IMPORTANCE OF PHYSICAL AND ECONOMIC FACTORS. THE MODELS ALSO ARE USED TO FIND COSTS IMPUTED BY PRESENT DESIGN STANDARDS. /AUTHOR/
