The local displacement in the downstream of the embankment dam has been observed since the 2nd precise inspection was investigated. It appears that this displacement is caused by the differential settlement on the different properties of the zone during the construction. Therefore, using the advanced inspection method of the 3D scanning determines whether to proceed with the displacement. In this study, reviewing a field application and analyzing results of the 3D scanning method are drowned a conclusion for improvement in the inspection and maintenance method on the Rock-fill type embankment dam.
