Given the uncertainty as to the behaviour of the diffuser designed in the preliminary project and environmental impact assessment phase, INCREA was asked for a complete study of initial dilution (using the CORJET model) for two purposes:

. To calculate the initial dilution in the different phases of operation of the desalination plant

. To calculate the number of outlets that must be open during each operation phase to ensure the proper initial dilution.

The characteristics of the brine outfall are:

. A diffuser section 200 m long with 20 outlets, separated 10 m apart with a dumping angle of 45º and a face diameter of 198 mm.

. Dumping depth 21.2 m

. Variable flow rate based on the number of lines

. Salinity: 73 psu
