Abstract

The invention discloses a method and system for determining the transport flux of pollutants in a sea area section, and relates to the field of pollutant diffusion in the sea area. The numerical simulation data of the tidal current is interpolated on the measuring points of the sea area section to be detected, and the water depth, flow velocity and flow direction corresponding to the measuring points are extracted; Average flow rate; Interpolate the data of marine pollutants at the measuring points of the sea area to be detected to determine the average concentration of pollutants between two adjacent measuring points; determine the transport channel of pollutants in the sea area to be detected according to the average flow and the average concentration of pollutants quantity. The invention can realize the detection of pollutant transport flux in the sea area with complex flow state.

Description

technical field [0001] The invention relates to the field of pollutant diffusion in sea areas, in particular to a method and system for determining transport flux of pollutants in sea area sections. Background technique [0002] With the rapid development of coastal economy, my country's coastal water environment continues to deteriorate, and marine ecological functions are seriously damaged. Coastal water pollution is a global environmental problem that will seriously affect the health of the marine ecosystem and the sustainable development of the marine economy. Human activities in the coastal waters are often dense, and they are important functional areas such as breeding areas, scenic tourist areas, and marine protection areas. Therefore, it is extremely urgent to control pollution and protect the water environment of coastal waters. Reasonable calculation of sea area pollutant transport flux is the premise and foundation of sea area pollution control; establishing the...
