Abstract
The rate of initial development and its characteristics play an important role in the design of wastewater discharge into the sea. It is very common to use mixing zone models to estimate the initial gradient. Considering that salty sea water causes environmental damage due to mixing with wastewater discharged from the desalination site into the sea on the coasts, it was determined by modeling the angled channels that distribute the wastewater on the sea floor that the wastewater from the water site The sweetener enters the sea through the angled channels of the spreader and is pulled towards the shore due to the speed of the current. The lowest density is in the areas between the spreaders, which shows that the promotion system works well and prevents the sedimentation of the effluent on the sea floor and has reduced the density of the effluent. Also, the lowest speed is in the areas between the spreaders, which shows that the promotion system works well and prevents the sewage from settling on the sea floor.
