Title

FIELD EVALUATION OF SURFACE IRRIGATION MODEL (SIRMOD)(CASE STUDY IN FURROW IRRIGATION)

Pages

  1-10

Abstract

 SIRMOD is a simulation model used in design and management of surface irrigation system. In this model, Saint-venant equation is solved by Full Hydrodynamic (HD), Zero-Inertia (ZI) and Kinematic Wave (KW) methods. Performance of this model was evaluated in the field. This study was conducted on a clay soil located in research fields of University of Tehran. Flows of 0.8-1.2 l/s was deliverd to 200 m-long furrows with 0.75 width. Field tests for determining of ADVANCE rate, RUNOFF, INFILTRATION, flow geometry and inflow rate were conducted and the results were compared with SIRMOD model. The results show HD, ZI and KW models estimate ADVANCE and INFILTRATION rates to be less than field observations. This study shows that ADVANCE rate of HD model is closer to field observations than ZI and KW models. In RUNOFF comparison, model eoverstimated the observed data. Therefore overestimation of RUNOFF inevitably result in lower estimation of INFILTRATION volume.
