Mathematical modelling for distribution of heavy metals in estuary area of Red River (Vietnam)
In this paper, the authors studied the features of spatial distribution of some heavy metals (Pb, Hg, As) in the system "suspended substance - bottom sediments" in the mouth area of the Red River (Vietnam). A mathematical modelling for diffusion processes of heavy metals in a suspended for...

| description | In this paper, the authors studied the features of spatial distribution of some heavy metals (Pb, Hg, As) in the system "suspended substance - bottom sediments" in the mouth area of the Red River (Vietnam). A mathematical modelling for diffusion processes of heavy metals in a suspended form, in bottom sediments and the spatial analysis for the results of these models were proposed and implemented. The studies were carried out during main hydrological seasons of 2014 - 2016 (during the flood and inter-natal periods). The propagation of heavy metals was modeled by solving the equation of turbulent diffusion. A spatial analysis of the content of heavy metals in the suspended form and in the bottom sediments was implemented by using the interpolation model in ArcGIS 10.2.2. The distribution of Pb, Hg, As concentration of the suspended form and bottom sediment phases in the estuary area of the Red River was characterized by maximum in the mouths of the branches and general decreasing gradient towards the sea. Maximum concentrations of Pb, Hg in suspended forms were observed in the surface layer of water at the river-sea barrier. The content of Hg and As in the estuary region of the Red River was observed in the following order: SSsurf< SSbott< BS; and content of Pb - SS >BS. |
