The study of dilution operations of sewage water pollutants through the sea outfalls in both far field and near field are no more than two sides for one coin. Regardless of dilution operations in near field, dilution operation in far field have been studied by various references, the closest of which to reality is "Gauss Distribution "already accredited in our study as foundation for determining mathematical models that study mass balance for mixing processes through lateral eddy diffusion in a plume form, and study and analyze the models in both cases of steady and instantaneous state plume.

In this regard rises the importance of Richardson Law(1926)concerning horizontal lateral diffusion of pollutants, to which the modern scientific references resort for conformity of results. The study of coastal sea water quality to be fit for swimming requires concluding the bacterial inactivation factors. Thus, calculation of controlling Parameters of pollutants lateral diffusion gives the chance of approximation between the theoretically calculated or estimated values of pollutants and their realistic ones. The research includes the information and surveying monitoring program required for establishing a whole and integral model to help in determination and prediction Of the various pollutants status in water environment of whatever nature and in different times.
