                                Summary

PLUMES
~~~~~~
PLUMES includes two initial dilution plume models (RSB and UM) and a model
interface manager for preparing common input and running the models.  Two
farfield algorithms are automatically initiated beyond the zone of initial
dilution.  PLUMES also incorporates the flow classification scheme of the
Cornell Mixing Zone Models (CORMIX) with recommendations for model usage,
thereby providing a linkage between the systems.  PLUMES models are intended
for use with plumes discharged to marine and some freshwater bodies.  Both
buoyant and dense plumes, single sources, and many diffuser outfall
configurations can be modeled.
