Rameshk is one of the villages of Ghaleh Ganj city in Kerman province. Construction of underground dams is one of the most effective ways to deal with water crisis and dehydration, especially in arid climates such as this village. For an underground dam to have an efficient yield, an accurate and optimal combination of the location of the dam and the engineering of the underground dam is necessary. In this regard, the failure and error in estimating either of these factors significantly lower the efficiency of the underground dam. In this study, considering the most important factors required in selecting a suitable site for underground dam construction, the proposed axis for Rameshk Dam underground is investigated through desktop studies, field surveys, engineering geological studies, and geophysical exploration. According to the satellite images and data from drilling and geophysical methods, there is a fault at the selected axis. Also, the thickness of the alluvium at the intersection of the fault and the selected axis is 32 m. The results show that the alluvial in the location of the selected axis is mainly of SC type. Based on SPT and Lefranc test data, the results show that with increasing the depth, the dam site is highly dense and permeability is reduced. Alluvial compaction with increasing depth, calcite cement between grains from depths of 15 m and below, and the water table at a depth of 7 m indicate that the probable fault location of the proposed axis does not have much drainage power. Although it is not an ideal option, it is suitable for constructing an underground dam regarding the regional and economic conditions of the study area.
