The complexity of water resources management issues has made it difficult for managers to consider all aspects necessary for comprehensive water resources management and planning. Therefore, the use of multiple decision makers with different specialties and skills. in the decision-making process of water resources is necessary. So, the purpose of this study is to provide practical strategies for sustainable development of water resources

In this study six and eight standard was defines. The ANP network structure was created, and the pairwise comparison matrix, weighted matrix and limit matrix were calculated. In order to prioritize strategies through the FUZZY - TOPSIS method. Then the weights of the expression criteria were converted to triangular fuzzy numbers. After the decision has been made to normalize and weight the matrix, differences in strategies were obtained from positive and negative ideals, the option with the higher proximity coefficient was ranked higher. In the combined method of ANP and FUZZY -TOPSIS, first the weight of each strategy is calculated by the ANP method and the weights obtained by ANP method were transferred to FUZZY -TOPSIS method.

The result show ANP model that mechanized agriculture and irrigation strategy is a top priority. While the calculation method of TOPSIS - FUZZY and ANP-TOPSIS- FUZZY introduced the strategy to promote the correct culture of water consumption and improve the cultivation pattern by cultivating plants with less water requirements and proportional to hydro-ecological potential, respectively.

Water is a vital substance that cannot be replaced. Excessive exploitation of water resources and drought have caused a severe decrease in the country's water reserves. In this research, the SWOT strategic management model was used in order to provide management strategies for the sustainable development of Songhor plain, Kermanshah, Iran. The obtained results indicate that the weaknesses and threats of the region prevail over the strengths and opportunities. So, a defensive strategy was proposed to get out of this situation. Considering that the SWOT model was not able to prioritize strategies, hierarchical analytical model was used for prioritizing strategies. The criteria of economic, feasibility, protection of natural resources and environment, social acceptability, adaptability, flexibility and durability were considered as the most important criteria for evaluating strategies. Finally, the strategy of promoting the correct culture of water consumption and mechanization of agriculture were placed in the highest priority from the expert's point of view with a relative weight of 0.139 and 0.134 respectively.
