This work focuses on the study of thermal dispersion of plumes emitted by power plants into the sea. Wastewater discharge from power stations causes impacts that require investigation or monitoring. A study to characterize the physical effects of thermal plumes into the sea is carried out here by numerical modeling and field measurements. The case study is the thermal discharges of the Presidente Adolfo López Mateos Power Plant, located in Veracruz, on the coast of the Gulf of Mexico. This plant is managed by the Federal Electricity Commission of Mexico. The physical effects of such plumes are related to the increase of seawater temperature caused by the hot water discharge of the plant. We focus on the implementation, calibration, and validation of the Delft3D-FLOW model, which solves the shallow-water equations. The numerical simulations consider a critical scenario where meteorological and oceanographic parameters are taken into account to reproduce the proper physical conditions of the environment. The results show a local physical effect of the thermal plumes within the study zone, given the predominant strong winds conditions of the scenario under study.

“…Many research groups have successfully applied the DESA method to incorporate bubble plumes into hydrodynamic lake models (e.g., Singleton et al, ). Morelissen et al () use the DESA approach to couple some CORMIX modules to Delft3D, finding good results for two test cases, and Morelissen et al () further extend the coupled CORMIX‐Delft3D model to handle high‐momentum buoyant line sources in the Sea of Japan. These outfalls are similar to the outfall in our case study with two important distinctions: they discharge into relatively deep water, where ambient stratification is relevant, and the near field extends only a few hundred meters, whereas our near field extends for many hundreds of meters.…”

This work is motivated by a case study in which cooling water effluent is discharged from a line source diffuser onto the shallow southern shelf of a large lake. The effluent is discharged with high momentum to the north, and the plume influences the surrounding flow for hundreds of meters before becoming a passive tracer. We plan to use a three-dimensional hydrodynamic model to examine the impact of this effluent on water residence time within the southern shelf, but in order to accomplish this task, we require a method for incorporating the effluent-driven flow into the hydrodynamic model, which by default does not predict the correct rate of spreading of the plume or the correct rate of lateral entrainment of ambient water. In this paper we develop a method for incorporating the effects of high-momentum line source discharges into any three-dimensional or two-dimensional (depth-averaged) hydrodynamic model that employs a horizontal eddy viscosity and diffusivity. Our approach is to modify horizontal eddy viscosity and diffusivity to enforce the correct rate of lateral entrainment of the plume. We validate the new method using three test cases relevant to our case study: a neutrally buoyant jet, a cylindrical gravity current, and a negatively buoyant jet.

In the article is considered the one of aspects of nature management regulation – an account of successive transformation of pollutants in a water body, that come with waste waters of industrial, municipal and agricultural enterprises. It is necessary at the determination of permissible pollutants emission with waste waters that doesn’t allow the excess of the permissible level of substances content in the control point of a water body. This problem is considered on the example of successive transformation of nitrogen-containing substances in the following transformation order: organic nitrogen – ammonium nitrogen - nitrite nitrogen – nitrate nitrogen. The topicality of the modeling of nitrogen-containing substances is conditioned by their role in water ecosystems functioning. At that existent mathematical models of natural water quality formation that take into account substances transformation contain the large number of unknown parameters. So, the use of such models in problems of nature management regulation is problematic, because identification of model parameters is a separate very complicated scientific problem. And existent models with relatively small number of parameters don’t take into account the natural pollution of water bodies, caused by the life activity of organisms; substance losses in the transformational chain are also possible. The improved matrix mathematical model of nitrogen-containing substances transformation without the indicated shortcomings is offered.
