Abstract: 

POOR PERFORMANCE OF FURROW IRRIGATION SYSTEM REQUIRE ATTENTION FOR THEIR IMPROVEMENT. IN ORDER FOR THE FULFILLMENT OF THE ABOVE-MENTIONED NEED, THE OPTIFUR SIMULATION MODEL HAS BEEN PRESENTED TO ESTIMATE, DESIGN AND OPTIMIZE THE PERFORMANCE OF THE FURROW IRRIGATION. IN THIS MODEL, FOR HYDRAULIC SIMULATION OF OVER LAND FLOW, THE BULK BALANCE FUNCTION IS USED AND THE SIMULATED ANNEALING OPTIMIZATION MODEL (SA) IS USED IN ORDER TO OPTIMIZE IT. THE SA MODEL OFFERS OPTIMAL DESIGN IN REAL CONDITIONS AND LIMITATIONS BASED ON VARIOUS DECISION VARIABLES (THE DISCHARGE OF THE WHOLE SYSTEM, FURROW LENGTH, FURROW GRADIENT AND FURROW WIDTH). FURTHERMORE, IN THIS MODEL FIVE PERFORMANCE INDICATORS INCLUDING APPLICATION EFFICIENCY (EA), WATER REQUIREMENT EFFICIENCY (ER), DEEP PERCOLATION RATIO (DPR), TAILWATER RATIO (TWR) AND DISTRIBUTION UNIFORMITY (DU); HAVE BEEN SIMULTANEOUSLY DEFINED IN A OBJECTIVE FUNCTION. IN THE PRESENT STUDY THE EFFECT OF DECISION VARIABLES ON THE IMPROVEMENT OF FURROW IRRIGATION SYSTEM HAS BEEN STUDIED USING OPTIFUR MODEL. THE CONCLUSION TO BE DRAWN FROM THE PRESENT STUDY IS THAT, THE OPTIMIZATION OF FURROW IRRIGATION PERFORMANCE ESTIMATES THE INDICATORS OF APPLICATION EFFICIENCY PERFORMANCE (ER), DEEP PERCOLATION RATIO (DPR), TAILWATER RATIO (TWR) AND DISTRIBUTION UNIFORMITY (DU) IN THE FOLLOWING MANNER, 81, 3.5, 15.5, 97 PERCENTAGES, WITH REGARD TO THE FURROW LENGTH DECISION VARIABLE. IN ADDITION, THE OPTIMIZATION OF FURROW IRRIGATION PERFORMANCE ESTIMATES THE INDICATORS OF APPLICATION EFFICIENCY PERFORMANCE (ER), DEEP PERCOLATION RATIO (DPR), TAILWATER RATIO (TWR) AND DISTRIBUTION UNIFORMITY (DU) IN THE FOLLOWING MANNER, 88, 8.5, 3.5, 94 PERCENTAGES, REGARDING THE IRRIGATION SYSTEM WHOLE DISCHARGE DECISION VARIABLE. IN THE END, IF WE OPTIMIZE THE PERFORMANCE OF THE FURROW IRRIGATION IN REGARD TO THE SYNCHRONISTIC COMPOUND OF THE FURROW LENGTH DECISION VARIABLES AND THE SYSTEM OVERALL DISCHARGE, THE PERFORMANCE INDICATORS INCLUDING APPLICATION EFFICIENCY, DEEP PERCOLATION RATIO, TAILWATER RATIO AND DISTRIBUTION UNIFORMITY WILL BE ESTIMATED IN THE FOLLOWING ORDER, 89.1, 7.7, 3.2, 95 PERCENTAGES. ACCORDING TO THE ABOVE-MENTIONED RESULTS, CONSIDERING MORE DECISION VARIABLES CAN IDEALLY IMPROVE THE INDICATORS OF FURROW IRRIGATION SYSTEM PERFORMANCE.
