Abstract: The half-circle is the ideal shape of the best hydraulic section of open channels, but semicircular channels are not practical to construct. The semicircular section is approximated by a composite section that is composed ...

Abstract: The slope classification concept has many applications in open-channel flow problems. Many analyses have been made to find the depth of flow necessary for generating a uniform flow of a given Froude number and roughness ...

Abstract: The specific energy equation has many applications in rectangular open-channel flow problems. The existing methods of solving this equation are as follows: trial-and-error solution, graphical solution, and design tables ...
