User Guide for CE-QUAL-ELV2: A Longitudinal-Vertical, Time-Varying Estuarine Water Quality Model.

This report is the user guide for a FORTRAN program that permits time-varying hydrodynamic and transport simulations of estuaries. It also includes a summary of the development of this program, with emphasis on the characteristics of estuaries, estuarine boundary condition, turbulence, and validation tests. CE-QUAL-ELV2, an acronym for the Estuarine Longitudinal-Vertical 2-Dimensional model, consists of the original Laterally Averaged Estuary Model LAEM plus the water Quality Transport Module WQTM. The LAEM program was developed for a test application to the Potomac Estuary from the then-current version of the Laterally Averaged Reservoir Model LARM. The References section of this report lists all the available documents describing the related development of the LARM and LAEM programs. This report contains an overview of the capabilities of CE-QUAL-ELV2 a summary of its theoretical foundation and a discussion of the validation tests a synopsis of estuarine characteristics, including turbulence, with reference to the Patuxent Estuary and a detailed discussion of the application procedure, again with reference to the Patuxent example. The appendices contain an input data description with examples and user notes for two auxiliary codes.
