Investment Methods in Sustainable Water Resource Management Using SAW Method

Abstract: water crisis resource management originates from limited resources has made it essential tostudy the prioritization of traditional and modern methods of sustainable water resource management. theobjective of such studies is to provide a list of prioritized traditional and modern methods of sustainablewater resource management. this research aims to study rainwater harvesting method and qanat as twotraditional methods of water production and transfer. cisterns (ab anbars) and the water consumptionpatterns in persian gardens are considered as two traditional and sustainable methods of water storage andconsumption. the modern methods have been extracted from the tennessee standard. from the existingmethods, using ground slope for water transfer, adjusting water pressure based on consumption rate,qanat, cistern, rainwater harvesting system, drip irrigation system, green roof, sustainable vegetativecover, water absorbing pavement, and rainwater collection system on the roof have been selected and theinvestment options are listed for updating and implementation purposes. the rate of energy consumption,lifetime of facilities, stationary of the method, costs of production and transfer, observing regionalmanagement pattern, use of local materials and professionals, and health issues are the criteria applied forthe prioritization of the items based on delphi method. the prioritization was carried out by saw (simpleadditive weighting method). according to the results, slope of the ground was the first priority of theseitems, and rainwater collecting system on the roof, the last priority.
