Abstract: Normal depth is an important parameter for the design of irrigation canals. Direct analytical solution of normal depth is not possible because of the implicit nature of governing equations. The solution usually requires ...

Abstract: The condition of choke-free flow in ovoidal sewers subject to a rise in bed elevation is considered. For a subcritical approach flow with a smooth and gradual transition zone, the maximum limiting rise in bed elevation for ...

Abstract: The Brent Reservoir was constructed in the mid-1830s and its siphon spillways were completed in 1936 to protect the dam from overtopping in the event of an extreme flood. Since completion, there have been problems with the ...

Abstract: The characteristics of a parabolic-bottomed triangle cross section are introduced. For this geometry the “best” hydraulic cross section is determined by using the undetermined multipliers method of Lagrange. For a given ...

Abstract: This paper presents a practical method to predict depth-averaged velocity and shear stress for straight and meandering overbank flows. An analytical solution to the depth-integrated turbulent form of the Navier-Stokes ...

Abstract: Field measurements of velocity and turbulence have been carried out in a study reach of the River Severn at Lower Farm near Shrewsbury during overbank flow. Acoustic Doppler velocity meters have been used for the field ...
