Description:
U.S. water quality policy includes the concept of a mixing zone, a limited area or volume of water where the initial dilution of a discharge occurs. he Cornell Mixing Zone Expert System (CORMIX1) was developed to predict the dilution and trajectory of a submerged single port discharge of arbitrary density (positive, neutral, or negative) into a strafified or uniform density ambient envrionment with or without crossflow. ORMIX1 uses knowledge and inference rules based on hydrodynamic expertise to classify and predict buoyant jet missing. ORMIX1 gathers the necessary data, checks for ata consistency, assembles and executes the appropriate hydrodynamic simultion models, interprets the results of the simulation in terms of the legal requirements including toxic discharge criteria, and suggests design alternatives to mixing, assumes a conservative pollutant discharge neglecting any physical, chemical, or biological reaction or decay process. he predictive results can be readily converted, however, to adjust for first-order reaction process. he results of the hydrodynamic simulation are in good agreement with field and laboratory data. n particular, CORMIX1 correctly preducts highly complex discharge situations involving boundry interactions, dynamic bottom attachments, internal layer formation, and buoyant intrusions.
