Measurement items of phenomena reflecting the overall condition of the structure during the measurement for safety management in the dam include water volume and displacement depending on the number of water leaks. Leakage measurements, which are important indicators to be measured on a dam, require significant accuracy and reliability. However, the dam design basis includes general measurement equipment, but the lower the limit for calculating the water leakage, and the lack of accuracy and reliability is a phenomenon. Therefore, in order to improve accuracy and reliability of the dam's major measurement items, the standards of the dam water measuring meter and the suitability of the water leak calculation formula (based on USBR) are reviewed to elicit problems and suggest solutions.

Recently, there are few cases of the Precise Inspection for Safety and Diagnosis for transverse crack of CFRD. The presumable causes and characteristics of transverse cracks have suggested in this paper based on field survey and related NDT. Also, the maintenance of transverse crack of CFRD are proposed.

‘Seismic assessment and retrofitting guidelines’ of the foundation and soil was published to ensure the seismic safety of the existing structures by MLTM(Ministry of Land, Transport and Maritime Affairs) and KISTEC(Korea Infrastructure Safety & Technology Corporation) in 2004. In this study, it is desired to figure out the improvement items through consideration and analysis of problems for seismic assessment and retrofitting guidelines, which are necessary to be supplemented and improved in this time.
