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.
