Abstract: Effects of discharge polluted by heat or some hazardous materials on waterenvironment have been arousing a worldwide interest.To estimate the effectshydraulic researchers have presented many numerical and physical models basedon the equations of fluid motion,continuity and heat and/or material conserv-ation.The motion equation consists of many terms including inertia,externaland Coriolis forces,Dressure gradient force and diffusion.Some terms amongthese,however,are generally omitted in the propose for simplification of cal-culations.In field near the outlet,the inertia force may be most predominant.When there exist coastal currents induced by tide,waves and other causes,thebehavior of effluent in the sea will be influenced by them.In the case thatscale of the effluent is large enough to reach the offing far off the land,theeffects of Coriolis force and oceanic currents may become predominant.Respecting this matter,interesting things are to know where the boundary divi-ding the near and far fields exist and how these two fields are interconnectedin the practical field.
