Abstract
In this study, water resources Decision Support System (DSS), which estimates quantitative indicators based on environmental, social and economical criteria under climate scenarios was investigated in the Aras river basin. The DSS analyzes the effects of management alternatives on balance of water supply and demand with simulating the water allocation between agricultural, domestic, and industrial demands. The Mike Basin water allocation model linked to Excel spreadsheet is used to evaluate the performance of 9 proposed indicators of management options and the Multi Criteria Decision Making analysis 'TOPSIS' is used to determine the best management options. The results indicated that the option of 'Reducing losses and Increasing efficiency' in the optimistic scenario and the option of 'Reducing losses and Reducing cultivated area in the scenario of continuation of current condition and pessimistic scenario are in the first rank. The individually alternatives of 'Don't water transfer to Urmia Lake basin' and 'Decrease cultivated area ' lied in the last rank.
