“…[12] implemented three-dimensional modelling for the simulation of water temperature distribution. There have been several studies that reported the use of commercial tools as the key tools for the simulation of thermal dispersion in nearshore coastal environments, estuaries, and lakes [15][16][17][18].…”

Environmental Impacts of Thermal and Brine Dispersion Using Hydrodynamic Modelling for Yanbu Desalination Plant, on the Eastern Coast of the Red Sea

et al. 2022

For any coastal desalination plant, the most effective and practical way to dispose of their brine is to thermally discharge it into the sea via outfalls at some distance from the coast. This study focused on the environmental impacts associated with brine and thermal discharge arising from seawater desalination plants at Yanbu, Saudi Arabia, on the southeastern coast of the Red Sea. The impacts associated with recirculation patterns and dispersions were investigated with the calibrated three-dimensional numerical model Delft3d. The environmental impact assessment and the process of identification and characterisation could help improve strategies for better planning and management of the technological solutions related to desalination. Analysis of the model simulations for the different seasons also suggested that around the outfall location, the magnitude of the flow was always high when considered together with the presence of seasonal eddy circulations. Although the tidal flow is lower, the ambient current and wind cause the far-field discharge to spread along the north–south direction during the winter and summer. The thermal and brine dispersion and environmental compliance were assessed in terms of the extent of dispersion. The well-mixed environment caused more rapid dispersion. From the impact level assessment perspective, the study indicated rapid dilution and dispersion of the wastewater at the study region. The present offshore outfall and further offshore locations were far enough to ensure quick dispersion.

“…[15,16] analysed thermal dispersion simulation results with the use of the MIKE software. In the Red Sea and Lake Ontario, a finite element model was used to simulate the thermal dispersion characteristics [17,18]. Thermal dispersion at the Bohai Sea was simulated by the COHERENS model [19].…”

“…Literature also reports the use of commercial soft tools for simulation of thermal dispersion in lakes, rivers and coastal environments [14][15][16][17][18][19][20][21][22][23][24][25][26]. Abbaspour et al [14], Lowe et al [15], Liu et al [16] and Ahmed et al [17] used MIKE software in order to estimate thermal dispersion in coastal and confined water bodies.…”

“…MIKE requires bathymetric data, stationary tidal variation, wind speed input and water discharge temperature to numerically estimate thermal dispersion. Demenet and Bae [18] and Prodanovic [19] used TELEMAC-3D to model the red sea and Lake Ontario respectively. Demenet and Bae [18] reported physical modelling of the red sea by scale ratio of 1:43.…”

Analysis of dispersion of heated effluent from power plant: a case study

et al. 2017

View full text Add to dashboard Cite

Thermal dispersion of heated effluent in a lake near nuclear power plant is analysed. Lake Bathymetry is established by data collection at a pre-planned matrix of sample points in the lake. Threedimensional geometric model of the lake is developed based on the geometric data collected, using a high accuracy GPS and a dead weight based depth meter at respective sample points of the lake matrix. A turbine type digital flow meter is used to measure the velocities at the intake and blow down points of the lake. Numerical analysis of flow and thermal dispersion is carried out using PLIC-VOF two-phase model with the two-equation k-epsilon model for turbulence closure. Numerical results for varying flow and blow down temperature conditions and wind speed are studied. It is observed that the thermal gradients are steeper in the curved area near the blowdown point. Small increase in main inlet (inlet II) velocity suppresses the dispersion of high-temperature contours significantly. Thermal discharge and dispersed temperature is monitored using temperature sensor mounted floating buoy at various locations in the lake. It is established that the thermal dispersion is influenced by wind velocity and the presence of water hyacinth in the lake.
