In dry and semidry regions, changes in precipitation in terms of time and level have significant fluctuations, which make management of water resources in these regions very important. The aim of this research is to first identify well-suited sites for constructing groundwater dams, such that there is no limitation for constructing such dams in these regions. For this purpose, by benefiting from Boolean logic and using the physiographic, topographic, geological, land-use, fault, and aqueduct criteria, the regions that had no limitation for constructing groundwater dams were determined. Next, using analytical hierarchy process as well as the quantity and quality criteria of water, economic and social, dam reservoir, and land use, the suitable regions for constructing groundwater dams were prioritized. The inconsistency rate in this research was obtained as 0.05. Investigation of the inconsistency rate indicated that the scoring performed for the criteria and sub-criteria studied here was acceptable. The results of prioritization of the region showed that the watershed slope is one of the most important criteria in determining suitable regions for constructing groundwater dams, and constructing dams at high slopes is not economical. The watershed slope to construct groundwater dams has been studied across all investigations dealing with site selection for groundwater dams. In this regard, the maximum slope for constructing groundwater dams has been considered as 5%. Furthermore, given the geological conditions of the region and high score of this criterion in constructing groundwater dams, this criterion should be paid more attention to in groundwater dam construction. Overall, the results indicated that the regions located in the western and central parts of the watershed had a higher score for groundwater dam construction. Considering the importance of groundwater dam in dry and semidry regions, it can be stated that by constructing groundwater dam in these regions, it is possible to improve the situation of water resources in the region.

通过布尔逻辑和层次分析法（AHP）选择地下水大坝的选址（案例研究：Imamzadeh Jafar Gachsaran的分水岭）

在干旱和半干旱地区，降水的时间和水平变化很大，这使得这些地区的水资源管理非常重要。这项研究的目的是首先确定建造地下水大坝的合适地点，以便在这些地区建造此类大坝没有限制。为此，通过利用布尔逻辑并利用地理，地形，地质，土地利用，断层和渡槽标准，确定了没有限制建造地下水坝的区域。接下来，使用层次分析法以及水，经济和社会，水坝水库和土地利用的数量和质量标准，优先考虑建造地下水水坝的合适区域。在这项研究中的不一致率为0.05。对不一致率的调查表明，对此处研究的标准和子标准进行的评分是可以接受的。该区域的优先排序结果表明，分水岭边坡是确定建造地下水大坝的合适区域的最重要标准之一，而在高边坡上建造大坝是不经济的。在所有有关地下水坝选址的调查中，都对修建地下水坝的分水岭进行了研究。在这方面，建设地下水大坝的最大坡度被认为是5％。此外，考虑到该地区的地质条件和该标准在修建地下水大坝中的高分，在地下水大坝建设中应更加重视这一标准。总体而言，结果表明，位于流域西部和中部的地区对地下水大坝的建设得分较高。考虑到干旱和半干旱地区地下水坝的重要性，可以说，通过在这些地区建造地下水坝，可以改善该地区的水资源状况。
