Using Multiple Criteria Decision Making (MCDM) for Selecting and Prioritizing of Existing Water Resources as Irragation Water (Case study: Green Area of Boienzahra City)

One of the key factors in the conservation and development of urban green space is use of available water resource in each region according to the characteristics of green space in this paper providing of water for boeen-zahra's green space irrigation has been studied.

First available water resources were determined then questionnaires completed by experts, and the effective criteria in the decision-making process of water resources selection were weighed using AHP (Analytical Hierarchy Process) method. Finally, the best option was selected using the preferential prioritization method to enrich the evaluations (Promethee).

The results of AHP method in Expert Choice software indicated that the weight of technical, practical and managerial criteria were higher than other options and water resources of municipal garden wells with miscellaneous wells were selected as the best option. In the second stage, the weights and scores obtained from the criteria and options of the first part, were selected and ranked as input to the Decision Lab 2000 software, and in this stage, the result obtained was confirmed in the first stage.

The present study indicates that technical, practical, managerial and environmental criteria are the most important factors in choosing the type of water source for irrigation of green space. In other words, in choosing the right water resources, achieving standards, hydraulic shock resistance, no need for advanced technology to control, system efficiency, are the parameters that are most considered.
