CORNELL MIXING ZONE EXPERT SYSTEM (CORMIX)
Description:
Cornell mixing zone expert system (CORMIX) can be used for the analysis, prediction, and design of aqueous toxic or conventional pollutant discharges into diverse water bodies. The major emphasis is on the geometry and dilution characteristics of the initial mixing zone -- including compliance with regulatory constraints, but the system also predicts the behavior of the discharge plume at larger distances. The highly user-interactive cormix system is implemented on microcomputers (IBM-pc, or compatible), and consists of three integrated subsystems: cormix1 for submerged single port discharges, CORMIX2 for submerged multiport diffuser discharges, and cormix3 for buoyant surface discharges. While CORMIX was originally developed under the assumption of steady ambient conditions, Version 3 also allows application to highly unsteady environments, such as tidal reversal conditions, in which transient recirculation and pollutant build-up effects can occur. Two post-processing models are linked to the CORMIX system, but can also be used independently. These are corjet (the Cornell buoyant jet integral model) for the detailed analysis of the near-field behavior of buoyant jets, and fflocatr (the far-field plume locator) for the far-field delineation of discharge plumes in non-uniform river or estuary environments. The users manual gives a comprehensive description of the CORMIX system; it provides guidance for assembly and preparation of required input data for the three subsystems; it delineates ranges of applicability; it provides guidance for interpretation and graphical display of system output; and it illustrates practical system application through several case studies.
