Abstract

The invention provides a forecasting method for influence of ship waste on a bathing beach environment under a strong wind condition. On the basis of a set of three-dimensional wave-flow-sediment coupled model on which an SWAN wave model, an FVCOM flow field model and an FVCOM sediment model are integrated, flow field and wave field information required by a pollutant diffusion model is calculated. According to the three-dimensional wave-flow-sediment coupled model, wind field data calculated through adoption of a WRF atmosphere model is taken as surface force, and tide information calculatedthrough utilization of a TPXO tide model is taken as a model boundary drive condition. According to the pollutant diffusion model, on the basis of a Lagrange particle tracking technology, various pollutant diffusion submodels corresponding to different pollutant types are integrated, and the influence of wind on motion of different types of pollutants is taken into full consideration in an oil pollutant diffusion model.

Description

technical field

[0001] The invention relates to the field of beach environment forecasting, in particular to a method for forecasting the impact of ship waste on the beach environment under strong wind conditions. Background technique

[0002] Pollutants that affect the beach environment include floating debris, fecal coliform bacteria, and petroleum, and the discharge of ship waste is also one of the main sources of these pollutants. After the ship waste is discharged from the hull, it can follow the ocean current for a long distance and cause serious impact on the environment of the passing beach. Numerical model methods have been widely used in the simulation of marine oil spills and the dispersion of pollutants, but most numerical models do not distinguish the types of pollutants when simulating the movement of pollutants, but generally treat pollutants as a class of substances . Obviously, different types of pollutants have different properties in the process of movem...
