A NOMOGRAPH BASED ON KINEMATIC WAVE THEORY FOR DETERMINING TIME OF CONCENTRATION FOR OVERLOAD FLOW

THE APPROACH AND PROCEDURES ARE PRESENTED FOR THE DEVELOPMENT OF A NOMOGRAPH THAT WILL ACCURATELY DETERMINE THE TIME OF CONCENTRATION IN THE RATIONAL FORMULA. THE KINEMATIC WAVE THEORY WAS USED IN THE ANALYSIS AND IZZARD'S AND THE CORPS OF ENGINEER'S DATA WERE USED TO DERIVE THE RESULTS. THE RESULTS SHOULD BE APPLIED ONLY TO CONCRETE AND TURF SURFACES. /FHWA/
