DESCRIPTION

Studies and Measurements Diagnosis of coastal morphodynamics. Calculation of wave conditions. Application of mathematical model of heat diffusion CORMIX. Calculation of sand income in the intake of CWS. Study of the thermal plume dispersion. Current measurements (Langranian and Eurelian). Scenarios simulation. Application of mathematical model OUTRAY. Recommended solution. The purpose of this study was to optimize the location of the intake and the discharge of seawater. The specific objectives were: To Prevent recirculation of water coming from the discharge to the Intake. To Reduce the possibility to have a variation in water temperature greater than 3 º C. in a radius of 100 meters around the intake. Minimize sand income to the intake. Minimize the physical impact of the intake and discharge into the seabed sedimentary processes.

SCOPE OF WORK

The scope of this study may be summarized as: Review background information of the physical parameters that influence the analysis and solutions, such as: Waves, tides, currents, seawater density and density gradients, seawater temperature and temperature gradients, etc. Define the distribution of grain size characteristics of bottom sediments. Diagnosis of coastal morphodynamic in the sector. Calculations of resuspended bottom sediments by waves and currents. Mathematical modeling of heat diffusion and dispersion. Analysis of the impact on the sedimentary processes by the solutions proposed.
