Flow in open channels has been nature’s way of conveying water on the surface of the earth since the beginning of time. The following physical properties of fluids influence fluid motion, channel geometry, and help explain sediment transport. These are: mass; density; weight; specific weight; viscosity; shear; temperature; and elasticity and surface ...

Streams and man-made channels have a free-water surface exposed to the atmosphere, so they are known as open channels. The cross-sectional area of flow can vary at a given place in a channel, and the velocity of flow depends on several variables. Pressure is atmospheric, and the energy causing the flow is elevational energy (gravity); gravity drives ...

An open channel is one in which there is a free surface at atmospheric pressure e.g. canals, rivers and pipes which are not running full.

Central schemes for open‐channel flow
International Journal for Numerical Methods in Fluids, 2003AbstractThe resolution of the Saint‐Venant equations for modelling shock phenomena in open‐channel flow by using the second‐order central schemes of Nessyahu and Tadmor (NT) and Kurganov and Tadmor (KT) is presented. The performances of the two schemes that we have extended to the non‐homogeneous case and that of the classical first‐order Lax ...

TO STUDY THE NONLINEAR EFFECT OF THE IRREGULAR SHAPE AND SLOPE OF AN OPEN CHANNEL ON THE FLOW, IT IS SUGGESTED THAT THE BROWNIAN MOTION MODEL TO SIMULATE THE CHANNEL IRREGULARITY BE USED. THE IRREGULAR SHAPE AND SLOPE OF A CHANNEL ARE CONSIDERED TO BE DETERMINED BY RANDOM WALK PATHS OF IMAGINARY PARTICLES.

Journal of Hydraulic Engineering, 2002
In 1965, Rouse critically reviewed hydraulic resistance in open channels on the basis of fluid mechanics. He pointed out the effects of cross-sectional shape, boundary nonuniformity, and flow unsteadiness, in addition to viscosity and wall roughness that are commonly considered.

In the previous chapters, we considered transient flows in the closed conduits. In this chapter, we discuss transient flows in open channels. A flow having a free surface is considered open-channel flow even though the channel may be closed at the top, e.g., a tunnel flowing partially full.

The chapter begins with the basic definitions and nomenclature used in open channel hydraulics and applied in the book. In the next sections the governing equations for flow and transport are derived, including unsteady gradually varied flow equations, steady gradually varied flow equations, storage equation and advection-diffusion mass and heat ...
