Calculation Methods and Application of a Hydrodynamic-Based Marine Pollution Mixing Zone

Abstract:

In water environment management, a mixing zone is an area within which the concentration of pollutants are allowed to be higher than the water quality standards and beside which the water quality should satisfy the standards. A reasonable range of a mixing zone is important for the water function and environment manage. At present, there is no agreed method for mixing zone calculation. In this paper, a new calculation method of a hydrodynamic-based marine pollution mixing zone was proposed; it comprehensively considered both the source intensity and the specific hydrodynamic conditions. The example results showed that the method could really reflect the mixed state after sewage entering into the sea water and could be used in a mixing zone calculation.
