Field Application of Transient and Steady-State Canal Models in Thailand

Document Type: Proceeding Paper

Part of: Irrigation and Drainage


A transient (unsteady) flow model for simulating the hydraulics in irrigation canal networks was developed and tested in Thailand. A steady-state hydraulic model was subsequently developed and tested at the same site in Thailand. Both of the models were designed not only to simulate canal hydraulics, but also to generate control structure and turnout opening values based on given water allocation schedules. The features of these models and the experiences in applying them to canal operation at an irrigation project are described.
