Evaluating Irrigation and Drainage Projects in Khouzestan Province: Application of Fuzzy AHP and TOPSIS Technique

In this study, for performance assessment of eight irrigation and drainage projects in Khouzestan province, a combined framework of FAHP and TOPSIS technique were used. The major criteria of economic, environmental, social, technical and managerial aspects and eighteen sub-criteria were considered for the assessing process. Needed data were obtained from Power and Water Organization of Khouzestan province. The results indicated that economic criterion with relative weight of 0.292 has greatest impact on the assessment process. The managerial, technical, environmental and social criteria rank next in effectiveness with weights of 0.276, 0.163, 0.152 and 0.117 respectively. Environmentally, the Gotvand project with a score of 0.931 is the most efficient and Shahid Rajaee project with a score of 0.390 is the least efficient project. Economically, Gotvand and Dimcheh irrigation projects with a score of 0.899 and 0.064 are recognized as the most efficient and inefficient projects. The results also showed that according to the overall score, the projects can be ranked as: Gotvand, Dez, Maroon, Dimcheh, Shavoor, Karkheh, Ramshir and Shahid Rajaee. The results suggest that Ramshir and Shahid Rajaee projects that have a relatively low yield, choose the Gotvand project as their pattern.
