Accurate gradually varied flow model for water surface profile in circular channels

(in lingua inglese)

A very accurate approximation of the Froude number of circular channels having an error in the order of less than 1% is presented in this paper. The Froude number was used in the governing GFV equation to develop an exact analytical solution of the water surface profile. The proposed solution has substantially improved the accuracy of estimating the water surface profile compared with the existing approximate method which underestimates the backwater length.
