The transition region solution asymptotically approaches the classical turbulent bore solution at higher bore strengths. In addition, the flow surface may become discontinuous if the flow depth changes rapidly such that the surface profile breaks, e. Spatially varied flow impact on resistance in corrugated pipes authors. The phenomenon of a hydraulic jump, one type of rapidly varied flow, will be presented first, followed by a discussion of the specific force. A separate rapidly varied flow analysis of the transition region between the undular and turbulent bore regimes anticipates the upper bound of the undular bore regime that is a feature of experimental observations. Rapidly varied flow is another type of nonuniform openchannel flow where the fluid depth changes rapidly over a small reach of the channel. It presents tables a to provide a comprehensive range of solutions of the colebrookwhite equation, covering standard diameters from 20 mm to 4000 mm plus 4500 mm.
