“…Parsa et al therefore considered the effect of wave characteristics on the vertical concentration distribution of oil. Their study found that wave steepness has a direct effect on the oil dispersion in the water column, the oil concentration tends to vary linearly with wave steepness, and the oil concentration increases with the increase in wave height or the shortening of the wave period [109,141]. However, the existing research results obtained are basically qualitative conclusions, lacking theoretically rigorous quantitative results, and also cannot properly reflect the vertical diffusion characteristics of oil, while the characterizing parameters such as vertical diffusion coefficient are still mainly referred to the relevant forms of sediment in the construction of oil spill models.…”

Accidentally spilled oil can cause great harm to the ecological balance of water once it enters the environmental waters. Clarifying its movement behavior and migration law in water has been the focus of environmental hydraulics research. This review starts from the mechanism of the oil spill migration process, and firstly reviews the kinematic characteristics of the smallest moving unit of the oil spill, the individual oil droplet, as well as focusing on several key aspects such as droplet shape, trajectory, terminal velocity and drag coefficient. Subsequently, considering the commonalities and differences between inland riverine and oceanic environments, different aspects of oil droplet collision, coalescence, breakage, particle size distribution, and vertical diffusion are discussed separately. Finally, the current status of research on the migration laws of accidental oil spills in environmental waters is summarized, and feasible future research directions are proposed to address the emerging research problems and research gaps.

“…Also, an equation was proposed to predict oil droplet size distribution. In addition, an experimental program is conducted by Reza Parsa et al [22] to investigate the vertical oil dispersion of surface oil spills in a regular wave field, and which determines the trends of oil concentration variations due to natural oil dispersion and formulate the magnitude and time of maximum oil concentration.…”

After analyzing and summarizing previous research, it is obvious that the characteristic parameter, surface spilled oil concentration, is the key limiting condition for the usage of the spilled oil vertical concentration distribution formula, because there are no appropriate field detection condition and measurements. However, the vertical concentration distribution should receive more attention in the environmental risk assessment in consideration of the location of the aquatic organism and the water intakes. Based on the formula of vertical concentration distribution, a mathematic calculation method of the characteristic parameter, spilled oil surface concentration, was put forward, which mainly applies to the stage of surface tension and viscous force for marine oil spill. That is to say we establish the response relationship of the vertical concentration and the surface concentration under the most unfavorable situation by integrating along the vertical direction to get the average concentration. Finally, the key characteristic parameter, surface concentration, is available and it can be used to predict the characteristics of the vertical concentration distribution, which will provide water pollution characteristic parameters for the emergency warning of sea water quality.
