Evaluation of Border Irrigation System through Simulation

The term ʹsurface irrigationʹ refers to a broad class of irrigation methods in which water is distributed over the field by overland flow. A flow is introduced at one edge of the field and covers the field gradually. In this study, ability of zero inertia and kinematic wave models has been investigated in surface irrigation simulation. In this study WinSRFR (Surface Irrigation Analysis, Design, and Simulation Software) has been used for Simulation Modelling of Border Irrigation System (close-ended). For border irrigation system considered under study, the best possible inflow rate (Q) may be 25.5 l/s, compared to existing 31.3 l/s and cutoff Times (Tco) may be 25 minute, compared to existing 30 minute; wherein the application efficiency (AE) may be increased from the existing 58% to 85%, low-quarter adequacy (ADlq) may be decreased from the existing 1.56 to 1.01 and deep percolation (DP) may be decreased from the existing 42% to 15%.
