Abstract: At present, the impacts of ships berthing have been rarely considered in the analysis and calculation of siltation and deposition reduction. In this paper, a 2-D mathematical model is applied to studying the current and sediment transport of a busy wharf in the Jintang waterway, and the simulated results of current and suspended sediment are verified by the measured data from the site. The influences of ships berthing on changes of the tide field and scouring and silting amaunt are studied. The calculated results show that the ships berthing hinders the flowing of the current, thus it results in reduction of the current speed and siltation. But the ships only affect their surrounding areas. Considering the berthing of ships, the max monthly sediment silting strength of NO.1 and 2 berths can reach up to 1.15 meters, which is more approximate to the measured data. For the heavily deposited areas, three kinds of schemes for siltation abatement are put forward, and the calculation and analysis of current and siltation after taking measures against sitation are carried out. For the siltation abatement, the dikes with different lengths have different effects. A comprehensive comparison show that the short dikes have effective effects on the siltation abatement. The scheme of short dikes is recommended for reduction of siltation in the dock basin.
