Model Information
For more information about this model, go to www.epa.gov
Spatial Resolution
The spatial resolution is defined at the stream reach scale.
Temporal Resolution
The model uses a monthly model time step and then performs subsequent statistical evaluations. Model output is peak stream flow or flood frequency.
Outputs
Outputs include fish population metrics.
