Deciding on the right area to set up damp for the purpose of sustainable development of water resources using TOPSIS method


Kamran R. O. Ahmed F. Vahidi and Rostam E. J

Nowadays, due to uncontrolled exploitation of ground water, the rate of water shortage has doubled. Accurate control and management of these water resources can alleviate the problem of drought inherently. Based on the statistics published by FAO (Food and Agriculture Organization), the need for fresh water is almost twice that experienced 21 years ago, while useful water resources have been reduced by half the number recorded 30 years ago. It seems that the number of fresh water resources that will be recorded in 2025 will be one-fourth of the number of useful water resources recorded in 1960. Meanwhile, danger of various pollutions for water resources frequently increased their value and importance. Taking into consideration the mentioned cases, if water resources are not managed in a better way, human lives will be threatened by the shortage of water. Thus, it is necessary to acquire the exact and up to date information about the condition of water resources and prediction of their situation in future in order to achieve optimum management for water resources. One of the management methods for water resources is Multi Criteria Decision Making. The results and findings of different studies show that in TOPSIS method, zone 3 with (0/755) point comes first among the 7 studied zones and thus it is the most appropriate zone to establish the proper damp. In contrast, zone 7 with (0/265) point comes last after zones 4, 2, 5, 6 and 1 with (0/668), (0/512), (0/492), (0/327) and (0/289) points respectively and so it is not suitable for establishing damp.
