To enable DWR to confidently use water quality models for decision making purposes, DWR requires the following:
- The person(s) planning to develop the model must have a scoping meeting with the MAB. This will ensure that the model will include all parameters needed.
- A modeling plan must be prepared following the scoping meeting with DWR. Guidelines for preparing a modeling plan can be found here.
- The model used must be listed in EPA's TMDL Modeling Toolbox, or the model code must remain available to the public. Other methods such as the load duration curve, and simplified tidal prism approach may be used when appropriate.
- A modeling report or other appropriate documentation, along with all associated modeling files, must be submitted to DWR for review. Guidelines for preparing a modeling report can be found here.
