Hello everyone,

I am familiar with the EPA's Cornell Mixing Zone Expert System (CORMIX), which is widely used for environmental impact assessments related to wastewater discharge. CORMIX offers three major subsystems for different discharge configurations and has proven effective in simulating site-specific scenarios.

However, I am looking for free and open-source alternatives to CORMIX that are used in the European Union or in other countries, which can predict and analyze plume characteristics and dilution in mixing zones. I would greatly appreciate any suggestions on such tools that are easy to install and user-friendly, particularly for modeling submerged discharges and surface discharges.

Thank you in advance for your insights!
