URBAN STORM RUNOFF INLET HYDROGRAPH STUDY. VOLUME 1. COMPUTER ANALYSIS OF RUNOFF FROM URBAN HIGHWAY WATERSHEDS UNDER TIME-AND SPACE-VARYING RAINSTORMS

The main objective of this study is to develop an accurate design method for computing inlet hydrographs of surface runoff, with average recurrence intervals of 10, 25, and 50 years, from typical urban highway by flood routing technique. The most comprehensive mathematical model based on the method of characteristics was developed for computing the runoff inlet hydrograph. All flood routing methods were extensively reviewed and the most efficient and accurate technique was adopted for the formulation of a numerical (computer) model including all the rainfall-runoff processes on a highway watershed. Accuracy of the computer model was then examined by comparing the computed inlet hydrographs with field data obtained both from the Corps of Engineers airfield experiments and from typical highway cross-sections in the Salt Lake City area.
