Investment Methods in Sustainable Water Resource Management Using SAW Method

ABSTRACT: Water crisis resource management originates from limited resources has made it essential to study the prioritization of traditional and modern methods of sustainable water resource management. The objective of such studies is to provide a list of prioritized traditional and modern methods of sustainable water resource management. This research aims to study rainwater harvesting method and qanat as two traditional methods of water production and transfer. cisterns (Ab Anbars) and the water consumption patterns in Persian gardens are considered as two traditional and sustainable methods of water storage and consumption. The modern methods have been extracted from the Tennessee standard. From the existing methods, using ground slope for water transfer, adjusting water pressure based on consumption rate, qanat, cistern, rainwater harvesting system, drip irrigation system, green roof, sustainable vegetative cover, water absorbing pavement, and rainwater collection system on the roof have been selected and the investment 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 regional management pattern, use of local materials and professionals, and health issues are the criteria applied for the prioritization of the items based on Delphi method. The prioritization was carried out by SAW (simple additive weighting method). According to the results, slope of the ground was the first priority of these items, and rainwater collecting system on the roof, the last priority.
