| Abstract | This study focuses on the calibration of the Irrigation System Management and Operation Model (SYMO) by using the observed data at the site with real-time operation of The Phitsanulok Irrigation Project, Thailand. Controlled and efficient operation of a very long main canal is difficult to achieve. By using this model to describe hydraulic behaviors based on the Saint Venant equations for unsteady flow in open channel is found very important. In order to calibrate the model, all hydraulic parameters were measured from the field and inputted to the model. Discharge and stage were chosen for the given boundary conditions at upstream and downstream of each reach respectively. The optimum value of roughness coefficient were found by minimizing errors of simulated and observed stage in the unsteady flow model. While the fluctuating offtake outflows will affect to the simulation results directly making very difficult calibrated model. The calibration of hydraulic structures in the main canal and offtake structure was carried out. The results are compared to the observed data with real-time operation and found excellent. The management of an irrigation canal system can be simulated to use for either planning or monitoring in order to better efficient operation and management of the irrigation project to efficiently operate and manage the irrigation project. |
