ISC3
ISC3 model is a popular steady-state Gaussian plume model which can be used to assess pollutant concentrations from a wide variety of sources associated with an industrial complex.
This model can account for the following:
- Point, area, line, and volume sources
- Settling and dry deposition of particles
- Downwash
- Separation of point sources
- Limited terrain adjustment
Very recently, the status of ISC3 as a Preferred/Recommended Model of the US Environmental Protection Agency has been withdrawn, but it can still be used as an alternative to the Preferred/Recommended models in regulatory applications with case-by-case justification to the reviewing authority.
