Abstract
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. Hydrologic data such as the rainfall intensity, runoff flow rate, air temperature, wind velocity, and soil moisture content were collected during rainfall seasons in 1972 and 1973 on two urban highway watersheds in the Salt Lake City area, Utah. These data were used in the verification of a mathematical model simulating the surface runoff from such highway watersheds. The difficulties and inherent problems associated with field data collection from urban highway cross-section are discussed and possible remedies recommended. Hyetographs and the corresponding hydrographs of major storms which occurred in 1972 and 1973 at both sites are presented. Watershed infiltration capacities of sideslopes at both sites are empirically evaluated.
