Recursive algorithm for steady flow in a canal network

Abstract

A recursive-iterative algorithm to solve the equation for one-dimensional gradually varied steady flow in a canal network is developed. The recursion is used to sweep up and down the network, whereas iterations are used to obtain convergence for the discharge distribution at canal junctions. The convergence characteristics of different discharge updating techniques are discussed. The application of the algorithm is demonstrated through eight test problems on two networks, by starting the computations from different initial guesses of discharge distribution in the network.
