This paper aims at examinig the behavior of oil, droplets beneath an oil slick at water surface confined by a floating oil barrier in its upper and lower reaches. By analyzing the features of oil droplet formation, transport, diffusion and floating, the oil droplet transport and diffusion equation was established, the boundary condition was given and then the fourpoint difference form was worked out, with which numerical computation was conducted. According to the orthogonal experiment table L 8(2 5), a numerical experiment was carried out. On the basis of the direct analysis of the orthogonal experiment, from dimensional analysis and curve fitting, for determining the pollution zone in depth of oil droplets beneath water surface and the corresponding longitudinal coordinate, an empirical formula was resulted for parameters describing the changing law of oil concentration on water surface in the lower reach.
