Abstract

The aim of this paper is to pose a broad model for the hydraulics of overland flow by assessing the dependence of the friction factor on an inundation ratio at 3 stages of progressive flow inundation. The development of the model is prefaced by a brief review of the physical variables which may contribute to flow resistance and some of the possible dimensionless groupings arising from those variables. Previously published field and laboratory data are re-evaluated in terms of the frictional resistance as a function of an estimated inundation ratio for each flow, and the results are compared with the trends predicted by the model
