This study is on the stability re-evaluation of armor stones in saemangum seadike according to recently increased sea-level and frequent high waveincoming and the results are in the following. The field inspection of armor stones in the seadike revealed that damages of armor stones have been causedby higher waves than designed waves and that the reconstruction of armor stones and concrete grouting method have been used as the reinforcementwork. The result of numerical simulation of wave channel conducted to estimate the safety weight of armor stones influenced by flows revealed that thesafety weight of armor stones in the seadike No.4 was estimated as 5.47 tons by using the Isbash method, which is about 122 % more than 4.49 tonsestimated by using Van der Meer method. Therefore, in designing armor stones which can be influenced by high waves such as the case of Saemangumseadike, it is necessary to apply the safety weight method of armor stones, based on the Isbash method, which produced the significant figures among thesafety weight methods using flows as well as the safety weight method using high waves based on the Hudson method.
