A Laboratory Rig for Testing Runoff from Paved Surfaces
When a process is too complex for rigorous mathematical formulation, and simplifying assumptions are introduced for its solution, experimental verification is required, or the approximate numerical model cannot be said to represent the process. Numerical solution of the dynamic wave equations for flow over pavement is such a case. This chapter describes a laboratory rig used to test the numerical procedures and the initial storage theory developed for overland flow. The experiments were conducted in the Department of Civil Engineering at the University of Natal in Durban. Laboratory conditions were stringently controlled.
