Optimal Allocation of Water Reuse Using Modified TODIM-GP Approach with Considering the Leopold Matrix Outputs

Abstract

Allocation of water use is one of the most important challenges of water resources management that needs to evaluate water reuse options, especially in areas with limited water resources, arid climate, increasing water demand due to population growth. In this study, the modified TODIM method (Multi-Criteria Decision-Making in Portuguese with considering the risk preferences of decision makers) that can be used with goal programming (GP) by considering Leopold matrix outputs in order to preform Environmental Impact Assessment (EIA). The present study is aimed at optimally allocate water reuse to multiple stakeholders in Najafabad, Isfahan, Iran. The results showed that the numerical model developed with an integration of optimization and quantitative evaluation can be considered as a useful tool to develop feasible guidelines for adapting the requirements of different stakeholders for optimized allocation of recycled water.
