Abstract: 

Hydrodynamic models are suitable tools for understanding hydraulic behavior of large and complex networks which can evaluate network performance and improve their operation and management. FLDWAV model is a kind of hydrodynamic model with wide capability which basically has been developed for using in rivers. The model is included by routing different methods considerable variety of boundary condition and accessible source code hence it can be used in unsteady flow of irrigation and drainage network. The purpose of this study is testing and accommodating the results of FLDWAV model with experimental data, thus the elongated trapezoidal channel was constructed and by the use of collected observation data was evaluated model performance and its application for irrigation and drainage networks. Two hydrographs were produced with different properties and their data was compared with several testing model results from simulating unsteady flows in channel without calibration and with calibration. The results show that FLDWAV model is suitable for simulation of unsteady flow with eligible accuracy. Open source model prepares capability to accommodate model with different conditions in experimental structure and according to multiple advantages its application is advisable in operation improvement and rehabilitation of irrigation networks.
