The purpose of this study is to save maintenance dredging cost at Sam Chuk harbor which is located on the east coast of Korea and deposited silt of 140,000㎥ annually by drifting of sands. We have tested 4 cases of littoral drift experiment and 2 cases of stability of break water experiment. In littoral drift experiment, we prolong the length of groyne about 200m which reaches depth of -7.5m for the ship of drift of -7.5m in spite of limits of depth of sediment move ment being -12.0m in this harbor. We arrange break water parallel to groyne to protect entrance of littoral drift from north side. In the first case, the scale of sectional stability of break water are as follows: H 1/3 6.5m T= 14.0 sec. Height of break water= 5.5m The slope of harbor side =1 : 1.5 *Engineer of hydraulic model study section. The slope of sea side = 1 : 2 In the second case, we design the section with the result of first case. The brief of littoral drift experiment is as below. In case A, the amount of accumulate and calmness are smallest at entrance of harbor, but the other parts is more than any other cases. In case C, the scouring drift moved to entrance harbor side and estuary side of 0. Sip Cheon, therefore, the amount of de position is more than case A. and calmness is more than case A. Case D is similar tendency case C and the amount of deposition is more than case C. Therefore the order of good case is A, C, D and B the result of sectional stability break water which summarized from case I and case II are as follows. (1) The weight of cap is satisfied. (2) The Crest EL, (+5.5m) and the width (12.0m) is also satisfied. (3) The armor stone (0.8㎥) of harbor side slope should increase 2.0㎥ in size. The sea side slope (1 : 4/3) is unease, so it needs the elope (1 : 2) using T.T.P. (20 ton).
