Integrated interpretation of the three results together with several field evidences can help verifying the current condition of the old earthen dam. The applicable techniques are applied to twenty six earthen dams of RID for a five- year research project, and finally, exhibit a flowchart for the old earthen dam inspection by using integrated geophysical techniques. Solutions and recommendations from the research lead to big changes in maintenance and/or retreatment program of the RID dams in the present day. Keywords— Dam inspection, GPR, MASW, Resistivity. Fig. 1 Flow chart showing criteria of dam inspection, using geophysics. Note: at least resistivity, shear wave velocity and GPR play key technique in this account 846
