Abstract：A computer model for simulating unsteady flow in irrigation pipe network was presented in this paper based on the characteristic line (MOC) method. The method established the pipe network structure using branch-node association and node-branch association tables. We discussed how to store, calculate the pipe network data. In the calculation, different types of nodes and pipe network parameters were stored by arrays. As an example, we took the pipe network in spring irrigation and calculated and analyzed the unsteady flow within it. The results showed that the method for storing the pipe network was simple and convenient, and the node types could be iden-tified quickly in calling the subroutine for the boundary condition. The model can be used to simulate and analyze unsteady flow in complicated irrigation pipe network.
