DRAINAGE OF PAVEMENTS UNDER NONUNIFORM RAINFALL

A desk-top method is presented to predict the maximum runoff from pavement-gutter systems produced by temporally nonuniform rainfalls. The method is founded on the kinematic-wave solutions of the pavement and gutter flows. The governing equations are written in terms of three physically based nondimensional parameters. For a specified time pattern of rainfall intensity, the constant values of these parameters imply hydraulic similarity of an infinite number of different pavement-flow-gutter-flow situations. An implicit finite-difference technique is employed to solve the governing equations. The mathematical model is verified using a set of existing experimental data. Based on the concept of hydraulic similarity, a group of charts is developed to predict peak gutter-flow rates. (Edited author abstract)
