Scenario of the water quality modelisation:

-Pollutant : Escherichia Coli (bacteriological pollution)

-4 different pollutant sources

-Flow of the sources imposed constant and equal to 1 m3/s

-Pollutant concentration in the outlet equal to 1E9 EC/100 ml

Methodology proposed to interpret TELEMAC results is based on the European Directive concerning the Quality of Bathing Water.


Mandatory Value = 2000 EC / 100 mlGuide Value = 500 EC / 100 ml
