A new model and efficient formulation for the incorporation of various essential network components such as contractions and expansions, diffusers, valves, and booster pumps into the analysis of irrigation and distribution pipe networks is presented. The solution technique is based on the linear theory method, nodal head equations and the application of the finite element method. The finite element model results were compared with the results of a linear theory model. The correlation in terms of values of junction pressures and element flow rates was high. The advantages of the technique include reduced computer space requirement, implementation through existing finite element codes, simplicity of application to large networks, the ability to model and incorporate all essential network components into the analysis, and ease of use with large capacity and small computers.
