The Persian Gulf is one of the aquatic ecosystems which has recently been faced
with different pollutions. Cooling water discharges due to various industries such
as power plants can cause important disorders on the present ecosystem balance
and on aquatic creatures because of their high temperature. Thermal pollution
leads to their migration, crea...

... Typical examples include the application of numerical modeling with Delft3D-FLOW to simulate thermal plumes originating from the Veracruz Power Plant in the Gulf of Mexico (Durán-Colmenares et al., 2016), and the Yanbu-Saudi Arabia Power Plant (Aljohani et al., 2022). Numerical modeling of water thermal dispersion using MIKE has been carried out in different locations, including the Paiton Power Plant (Fudlailah et al., 2015;Fikri et al., 2020), Lekki Coast-Nigeria (Panigrahi & Tripathy, 2011), Bandar Abbas Power Plant-Iran (Abbaspour et al., 2006), and PT Kilang Pertamina International Kasim process plant in Sele Strait, West Papua (Yesaya et al., 2023). Additionally, the numerical simulation of water temperature in the R´ıo de la Plata River and Montevideo's Bay was conducted using the finite element numerical model RMA-10 in its 2D vertical integrated mode (Fossati et al., 2011). ...
... The modeling effort also included calculations near the emission source, using the Coupled to MIKE 3 Solution module. However, the verified results of hydrodynamic and thermal dispersion modeling using MIKE21 showed a similar pattern compared to field measurements (Abbaspour et al., 2006;Fikri et al., 2020). The results of the study conducted on the exhaust cooling system of LNG facilities in Kutch Bay, India, showed that the correlation coefficient between the modeling predictions and actual measurements was in the range of 86 and 98% (Gupta et al., 2014). ...

Muara Karang Power Plant (MKPP) is one of the main power plants on Java Island in Indonesia. Presently, the Jakarta provincial government has issued a reclamation project on Island G in the marine waters around MKPP. This reclamation effort is predicted to lead to a rise in the seawater temperature around the intake, which MKPP will address with the addition of intake channel of 250 - 957 m. Therefore, this study aimed to determine the effect of intake channel extension on the water temperature at the intake point using numerical modeling comprising hydrodynamics and dispersion advection modules. A total of 10 scenarios were modeled by varying intake channel length and season. The result showed that adding intake channel was less effective because the average water temperature was less than 0.24oC with an effectiveness below 0.78%. Based on the validation of the modeling results on the measurement data, the NRMSD values in west and east seasons were 9.13% and 12.63%, respectively. Under existing conditions, the average and maximum seawater temperatures were 31.40oC and 32.08oC. Meanwhile, by extending intake channel, the average and maximum water temperatures were 31.16oC and 31.60oC. These results showed that by extending intake channel, the temperature at the intake point was generally lower than the existing conditions. Intake channel length was more effective in reducing the temperature at the intake point during west monsoon than east monsoon. Vertically, the temperature at the bottom was relatively colder than near the surface. In west monsoon, the average temperature difference between the bottom and the surface ranged from 0.16-0.21oC, while in east, it was between 0.23 and 0.50oC. In conclusion, the addition of subsequent structures to increase effectiveness was necessary, specifically to hold hot water in east monsoon.
This work presents a numerical simulation of the distribution of heat sinks generated as a result of cooling generators of nuclear power plants in a natural reservoir. The aim of the work was to assess the thermal effect on the water area of Lake Balkhash, near the city of Ulken, where a site for a nuclear power plant was prepared. To obtain real results using computer modeling, the calculations took into account changes in air temperature, as well as the direction and speed of the wind in the area under study. One of the main tasks of the work was to evaluate the effectiveness of the use of jet-guide dams for natural cooling reservoirs. According to the obtained results, the longer the length of the barrier, the slower the heated water entered the tank for collecting cold water. Thus, the developed model made it possible to predict changes in the temperature regimes of the lake due to thermal pollution and to select the optimal volume of discharged water in order to minimize the negative impact. The obtained results will help to optimize the use of stream-guide dams for natural cooling reservoirs with real meteorological data.
Desalination is an energy intensive technology, especially when applied to seawater. Therefore, desalination has both high costs and a very large carbon footprint when conventional energy sources are used to power the various desalination processes. A variety of renewable energy sources are available that can be applied to reduce the carbon footprint of desalination. The global environmental impact of desalination can be reduced in terms of carbon dioxide emissions, but at a cost. Seawater desalination facilities will still have some environmental impacts on local areas related to intakes and outfalls of concentrate. Brackish-water desalination of groundwater can create a potential resource depletion problem and also faces the challenge of finding an economical and environmentally sound means of concentrate disposal, particularly for inland facilities.
The numerical simulation of the water temperature in the Río de la Plata
River and Montevideo's Bay was done using the numerical model of finite
elements RMA-10 in its 2D vertical integrated mode. Parameters involved in the
formulations of thermal exchange with the atmosphere were adjusted using
measurements of water temperature in several locations of the water body. After
calibrating the model, it was used to represent the operation of a power plant
located in Montevideo's Bay. This central takes water from the bay in
order to cool its generators and also discharges high-temperature water into the
bay. The correct representation of temperatures at the water intake and
discharge of the plant reflects that the model is able to represent the
operation of the central. Several analysis were made to study the thermal plume,
the effects of the water discharge on the water intake of the power plant, and
the effect on environmental variables of the study area like currents.
