In this study, a two–dimensional model is used to solve the problem of plastic waste transmission in the coastal estuary area of Da Nang–Quang Nam by DHI's MIKE 21/3 Couple Model FM model using hydrodynamic components (HD) and Particle Tracking (PT) applied to the problem of plastic waste transmission. Calculation results are calibrated, tested and simulated based on comparative assessment of water level factors between calculated and observated at hydrological stations (Cam Le, Cau Lau and Hoi An), marine–hydrometeorological stations. (Son Tra and Dung Quat) period 2018–2022. These results are evaluated according to the correlation index (R) greater than 0.9, the NSE index greater than 0.74 and the RSR index less than 0.2. From the calculation results of plastic waste transmission, there are seasonal fluctuations with specific typical months such as July 2021 (summer) with a tendency to move from South to North, December 2021 (winter) with a tendency to move from South to North. direction of movement from North to South.The calculation results show that it is possible to develop further studies with more realistic input conditions.Trong nghiên cứu này sử dụng mô hình hai chiều để giải quyết bài toán truyền tải rác thải nhựa khu vực cửa sông ven bờ Đà Nẵng–Quảng Nam bằng mô hình MIKE 21/3 Couple Model FM của DHI có sử dụng thành phần thủy động lực (HD) và thành quy đạo vật thể trôi (PT) áp dụng đối với bài toán truyền tải rác thải nhựa.
