In this research the methodology of underground dams’ monitoring was expressed in order to study the effect of underground dam construction on the subsurface flows as a quantity or quality study. therefore a suitable site selected in the margin of desert in distance of 10 km from the east of Ravar city and the required investigation were done in several steps. Before constructing the dam the hydrological studies were done for for determining the volume of subsurface flow which passed from the alluvium of the river in the place of dam construction. In first a borehole which dug well excavated and used for pumpage test to determining the hydrodynamic coefficient and subsurface flows calculating. Then four piezometric well were drilled by percussion and rotary method in which two of them were in the upstream (one of them with a distance of 800 meters and the other with a distance of 850 meters from the underground dam axis) and the other two piezometric well were in downstream(one of them with a distance of 100 meters and the other with a distance of 150 meters from the underground dam axis) and they were piped and equipped for the monitoring operation in future. After constructing the dam , the well was collecting and tansfring the water of dam reservoir was prepared and equipped. Immediately , after complementing the dam’s constructing operation, measuring of the underground water level was stared in 4 peizometric well and the dam’s water transferring well.this operatioin was continued during the periods of 1 to 4 months for 4 years.and also measuring underground dam’s discharge was carried out during the different periods. Then the data were analyzed the results shows that the construction of dam has been very sussessfuly and was shown the positive effect on the underground flows as the quantity or quality.
