A computer model was developed to simulate pressure and flow rate distribution along pipes and laterals of pressurized irrigation systems in operation. The software runs in a WINDOWS environment and is capable of simulating irrigation systems having multiple pump stations combined in series and/or in parallel, booster pump stations, parallel pipes and looping pipes. Hand-move, wheel line and center pivots laterals having pressure regulators, one or two drop pipes per outlet and booster pump can be simulated. Leakage can be included in the main pipe network or along the laterals. Plugged or worm nozzles can be accounted for in the model. The inlet pressure of laterals can be set to an upper limit to simulate valve closure. Independent pipe characteristics, nozzle, pressure regulator and slope data can be entered for each lateral segment pipe and nozzle. Pratically any type of nozzle and pump can be simulated since cubic spline functions are used to interpolate values from head-flow rate sets of data. To accomplish these capabilities, algorithms were developed and adapted to convert laterals a set of head-flow rate data so that a simplified algorithm could be adapted to salve the entire pipe network. A user-friendly interface was designed to allow data for pumpus, nozzle and pressure regulators to be interactively entered, edited and analyzed prior to the simulation run. The layout of the irrigation system can be drawn on screen by using the mouse. Data can be independently entered and edited for each (...)
