Ambient current begins at 2 m/s right to left, then reverses. In tidal mode, CORMIX gives estimates of reduced dilution due to tidal re-entrainment. Minimum initial dilution generally occurs shortly after slack tide, when re-entrainment of the plume from the previous tidal cycle occurs. Laser Induced Fluorescent (LIF) images courtesy of J.

4. Remote Sensing and Outfall Monitoring

With USEPA SBIR Phase II program support, MixZon Inc has developed an aerial remote sensing system for monitoring water quality at site scales. We have demonstrated the ability of our platform to obtain geo-referenced water quality data from point source mixing zones.

More details about the aerial remote sensing project and MixZon Inc's outfall monitoring services are available at the following MixZon websites:

5. OR DEQ IMD on Regulatory Mixing Zone

The Oregon Department of Environmental Quality (DEQ) OR DEQ has published its mixing zone guidance (officially known as the Regulatory Mixing Zone Internal Management Directive (IMD)) document.

The IMD went into effect on July 1, 2008.

OR DEQ now processes all completed and new permit applications received after this date under the guidelines contained in the IMD, as per their website.

The OR DEQ IMD documents can be downloaded from OR DEQ, using the links below:
