Abstract:

A two-layer two-dimensional mathematical model for transport and mixing of oil in rivers is presented. In this model, oil in the river is considered to consist of a surface slick moving on the water surface and a layer containing suspended oil droplets extending over the depth of the flow, with continuous exchanges of oil between the two layers. Oil slick transformation processes considered in the model include: advection, mechanical spreading, turbulent diffusion and mixing, evaporation, emulsification, dissolution, shoreline deposition, and sinking.
