Modelling Water Quality in a River

[cgomez@esph-sa.com]

Hi,
I will like to know which model you recommend for modeling the water quality in a river. The idea is to model process as BOD, OD, Nitrogen and E-Coli.
I am looking for a model similar to the QUAL2K model. I am familiar with Mohid Water however, I don’t know if I can use this one for what I´m want.
Looking forward for the response
Kind regards,
Cinthya
