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 boundary-value problem of one-dimensional infiltration resulting from rainfall is formulated and solved numerically on a digital computer. The numerical solutions of this idealized mathematical model is used as a basic testing tool in the subsequent analysis of various parametric infiltration models including the Green-Ampt, Kostiakov, Philip, Horton, and Holtan equations. The time of ponding is shown to be the most important …
