Abstract
This article presents a case study of numerical simulation of effluent in Konarak plant. by collecting data related to the case study which includes data such as output water characteristics of desalination (water concentration, discharge, temperature, outlet geometry), environmental conditions including wind speed in the region, the velocity of water flow, tidal velocity, tidal depth, and sea surface profile, to launch a numerical distribution model pollution at the seashore have been investigated using Cormix11 software at different depths and the effect of important parameters of effluent distribution on distribution and considering environmental conditions have been studied.
Numerical results show that increasing the discharge of effluent leads to more salinity in the sea. but in some cases, it can be managed with flow velocity and tidal time so that increasing discharge has less effect on water distribution in the sea.

Abstract
These days, the sea level rising and excessive harvesting of coastal aquifers has caused the intrusion of saltwater into underground water sources. In this study, the performance of the use of cut of wall, discharge well, and their simultaneous use in preventing saltwater intrusion has been evaluated in a laboratory model and under different scenarios. The results show that the appropriate use of the wall will reduce saltwater penetration by 15%. In addition, the use of a discharge well with flow rates of 0.065, 0.13, and 0.2 liters per minute will cause the return of salt water wedge by 5, 30, and 37%, respectively. The results of the simultaneous use of the discharge well with flow rates of 0.13 and 0.2 liters per minute and the cut of wall showed that the salt water wedge has retreated by 38 and 41%, respectively.
