In this regard, it is necessary to investigate the problems of agricultural water management in this network in order to find effective solutions to solve these problems by tracking the main problems. The purpose of this research is to investigate the challenges facing water resource management in the paddy fields of Sefidroud irrigation and drainage network. In this regard, after forming a decision tree based on the opinion of experts and reviewing the existing experimental models, the required data were collected through questionnaires and face-to-face interviews with the water sector experts of Guilan province. The decision tree has three levels, the first level has three sub-indices, the second level has 16 sub-indices and the third level has 85 sub-indices.
