The Hydraulic Performance and Surface Irrigation Fertigation under Different Inflow Hydrograph Shapes for Furrow Irrigation Bita Moravejalahkami Bita1114@ag iut ac ir Date of submission November 3 2010 Department of Water Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Behrouz Mostafazadeh Fard1 Email address behrouz@cc iut ac ir Manouchehr Heidarpour2 Email address heidar@cc iut ac ir Fariborz Abbasi3 S Saeid Eslamian4 Ernesto Vazquez Fernandez5 Abstract The correct selection of inflow discharge can improve surface irrigation performance In this study some modified furrow inflow hydrograph shapes were introduced and evaluated for field conditions A zero inertia simulation model was modified and an automatic device was designed and used to apply these inflow hydrograph shapes The Kostiakov Lewis infiltration equation parameters and roughness coefficient were estimated by multilevel calibration method using zero inertia model Fertigation were studied for these inflow hydrograph shapes The experiments were conducted on a furrow irrigation field with sandy loam soil texture Three replications were used for each measurement Samples from surface water were collected and analyzed for fertilizer concentration at different stations along the furrow The results showed that the tailwater runoff decreased significantly for the modified furrow inflow hydrograph shapes as compared to the constant furrow inflow hydrograph shape As the required irrigation depth increased the difference of application efficiency between the constant and the modified furrow inflow hydrograph shapes increased and the application efficiency was higher for the modified furrow inflow hydrograph shapes as compared with the constant furrow inflow hydrograph shape The fertilizer losses due to runoff decreased and the water application efficiency increased significantly for the modified furrow inflow hydrograph shapes Keywords Surface irrigation furrow inflow hydrographs zero inertia model fertigation 1 Professor Water Engineering Department College of Agriculture Isfahan University of Technology Isfahan 84156 83111 Iran 2 Associate Professor Water Engineering Department College of Agriculture Isfahan University of Technology Isfahan 84156 83111 Iran 3 Associate Professor Researcher Agricultural Engineering Research Institute Karaj Iran 4 Associate Professor Water Engineering Department College of Agriculture Isfahan University of Technology Isfahan 84156 83111 Iran 5 Associate Professor Researcher Institute of Engineering UNAM CU AP 70 472 CP D F 04510 Mexico
