Abstract : When dredging soft sea bottom sediments, it is important to estimate the suspended solids (SS) concentration in the effluent from the overflow weir. In some cases, special effluent treatment methods must be adopted to meet the SS concentration level and environmental quality standard. One effective means for reducting the SS concentration level of the effluent is to employ the SS removal ability of the diked containment area through the hydraulically appropriate layout of inlet/outlet or baffle walls in the containment area. To estimate the effluent SS concentration and to evaluate the sedimentation promotion, model tests were performed on the influence of the SS concentration in the influent and on the effect of inlet/outlet layouts and installation of battle walls in the containment area.
