1/T90 (1/seconds): This coefficient considers the half life of the pollutant if this disappears by means of chemical reactions (non-conservative pollutant). This is the T90 for E.Coli. For towns with less than 10,000 inhabitants we can take a T90=2 hours (1/T90=0,5 hours-1) in the Mediterranean and T90=3 hours (1/T90=0,33 hours-1) in the Atlantic.
Number of openings: DESCAR allows for different types of discharge geometries. There are three options: Single port, Multiport diffuser and Separated ports. We have a multiport diffuser when the separation among the ports is less than 3% of the depth. We have Separated ports when the separation among the ports is bigger than 20% of the water depth.
