The three-dimensional hydrodynamic model was established based on FVCOM, coupled with the Lagrangian particle tracking module to study the water exchange ability of 15 drain outlets of North and South Changshan Island. Meanwhile, the 30-day influence distance was introduced to quantify the water exchange ability. The drain outlets with a strong water exchange capacity are mainly located in the east of North and South Changshan Islands and the southwest corner of South Changshan Island, and those with a weak water exchange capacity are mainly located in the northwest corner of North Changshan Island, joint of South Changshan Island and the tombolo dyke and inside the Changdao Harbor. The 30-day influence range of the 15 drain outlets of North and South Changshan Islands is significantly affected by monsoon. East Asian monsoon accelerates the dispersion of the pollutants in the south sea areas of Bohai Strait.
