Locating and prioritizing the suitable place to build a pond with analytic hierarchy process (Northern region of Gorgan)

The integration of a multi-criteria decision-making system and a geographic information system was utilized to select appropriate locations for the construction of ponds. These ponds were intended to facilitate the storage and supply of water for agricultural purposes, the breeding of warm water fish, and the artificial feeding of underground water. This initiative was implemented in the flatlands to the north of the city of Gorgan. Thus, the Boolean model was used to locate the ponds, and the Hierarchical and Copeland analysis process was used to prioritize them. Google Earth was used to determine seven suitable axes for the construction of ponds in potential areas. The Hierarchy and Copeland analysis process was used to prioritize these places based on their main and sub-criteria. The results indicated that in the comparison of criteria with a consistency coefficient (0.03), the hydrometeorological criterion with weight (0.315) and the weighted rainfall sub-criterion (0.485) is the best criterion of hydrometeorology with the consistency coefficient (0.03) and the weighted sub-criterion of the slope of the area (0.394) is the highest criterion of geomorphology with the consistency coefficient (0.03) and the loan resources sub-criterion with weight (0.410) is the highest economic and social criterion with compatibility coefficient (0.004) and the sub-criterion of plant water requirement volume with weight (0.710) is the highest agricultural criterion with compatibility coefficient (0.004) and the sub-criterion of the cost of making a water seal by weight (0.349) is the highest technical criterion of construction with the compatibility factor (0.007) has been recognized as the superior criterion. The result of this work is that by dividing the layers of information with the composition, suitable places for the construction of dams have been selected. The findings of this research showed that the use of geographic information systems and decision support systems and the use of hierarchical analysis method as a powerful and flexible tool to reduce the complexities in identifying suitable places along with field visits in increasing accuracy, reducing costs and Determination has a role Location They are the place of construction of dams.
