Numerical Simulation and Evaluation of Fertigation and Hydraulic Performance of Meandering Furrow Irrigation Fatemeh Soroush E mail address fatemeh soroush60@yahoo com Date of Submission October 17 2012 Department of Water Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Behrouz Mostafazadeh Fard1 E mail address behrouz@cc iut ac ir Sayed Farhad Mousavi2 E mail address mousavi@cc iut ac ir Fariborz Abbasi3 E mail address fariborzabbasi @ymail com John D Fenton4 E mail address fenton@kw tuwien ac at Naim Haie5 E mail address naim@civil uminho pt Abstract Meandering furrow MF irrigation is a modified form of furrow irrigation which has being used in Iran but to date there are no studies on modeling of MF irrigation and field performance of MF fertigation Research was conducted to examine the effects of field slope on the hydraulic parameters distribution uniformities and application efficiency of water and fertilizer in meandering furrow irrigation Results indicated that application efficiency and advance time in MF irrigation were significantly more than standard furrow SF irrigation The average tail water runoff loss and consequently mass of fertilizer loss in MF were significantly less than SF In addition a furrow irrigation model was developed based on the Slow change slow flow routing equation The equation was solved numerically using explicit Euler and implicit Crank Nicolson schemes The model simulations of advance and recession trajectories and runoff were verified for different field conditions using filed data The model prediction of meandering furrow irrigation phases were in good agreement using field data In general the use of MF in sloping fields is recommended as a good management option for both irrigation and fertigation Also the proposed model can provide a suitable numerical simulation tool for design and evaluation of MF and SF irrigation for all slopes and boundary conditions Keywords Meandering furrow irrigation fertigation slow change slow flow routing equation numerical model infiltration 1 Professor Department of Water Engineering College of Agriculture Isfahan University of Technology Isfahan 84156 83111 Iran 2 Professor Department of Water Engineering College of Agriculture Isfahan University of Technology Isfahan 84156 83111 Iran 3 Associate Professor Agricultural Engineering Research Institute Karaj Iran 4 Professor Institute of Hydraulic and Water Resources Engineering Vienna University of Technology Karlsplatz 13 222 1040 Vienna Austria 5 Associate Professor Department of Civil Engineering University of Minho Guimaraes Portugal
