Abstract
Hot water discharge in marine environments, especially semi-enclosed seas and bays, has significant impacts on hydrophysical properties and the marine environment. The discharge of hot water leads to an increase in the surface temperature of the water and, as a result, a decrease in its density. These temperature changes and subsequent salinity changes affect the distribution of nutrients, such as nitrogen and phosphorus, and oxygen. Reduced oxygen levels, especially in areas near hot spring discharges, can lead to reduced water quality and the loss of marine life. In the Persian Gulf, where the depth is shallow and evaporation rates are high, these changes are more severe and will have more destructive effects on marine ecosystems. These environmental impacts can lead to ecological crises. In order to investigate the fluctuations in the hydrophysical properties of seawater and to accurately manage wastewater discharge in industrial units, it is necessary to optimally design and model the hot water discharge process to reduce negative impacts on the environment. Solutions such as using closed cooling systems, preventing water discharge in sensitive areas, and proper design for more uniform mixing and distribution of warm water can help reduce environmental damage and maintain the balance of marine ecosystems. In the present study, the MIKE software model was used to investigate and analyze the hydrophysical fluctuations occurring at the hot industrial wastewater discharge site in the Persian Gulf.
