Water quality synthetic forecast model for sea outfall

This paper introduces a 3-D synthetic model for simulating the diffusion of warm sewage pollution sources at weakly mixing sea outfall. This model considers the vertical velocity,the vertical gradient of flow field,the vertical temperature gradient and heat exchange of the region around sewage outfall. A multilayer 2-D model is used for the region for away from sewage outfall,which considers the velocity gradient and temperature gradient for every layer. The calculated results agree with the observative data.
