There are about 12,000 dams in Korea and large dams are about 1,200. The large dams are well operated and maintained by KWATER(Korea Water Resource Corporation), EKR(Korea Rural Community & Agriculture Corporation) and KHNP(Korea Hydro & Nuclear Power Co., Ltd.). Several research reports concern with the safety of these large dams are presented but there is no paper concerned with small dams which has tunnel in the middle of dam body.
The purpose of this study is to shows the common defects of small dams according to various cases of degradation of dams and the repair and retrofit methods which applied to the damaged dams. Also, this study tries to present the solution which concerned with these common defects in maintenance and design steps.
