CE-QUAL-W2 is a longitudinal/vertical hydrodynamic and water quality model that has received extensive use throughout the US and the
world as a management and research tool with more than 300 applications worldwide. V3 is a significant update to CE-QUAL-W2 V2 that
now includes the ability to model multiple waterbodies and the river reaches in between them. The model can now be applied to entire
waterbasins including rivers, reservoirs, and estuaries.
Author of the abstract:
A number of additional capabilities have been added to the kinetic routines in V3
including multiple algal, suspended solids, and CBOD groups, residence time, derived variables such as TN, TKN, TOC, chl a, total
dissolved gas, etc. The model now has the ability to be as simple or complicated as the application demands and the data allow. With the
addition of sloping river sections, the user now has the option to choose between various vertical turbulence closure and rearation schemes
depending upon the type of waterbody being simulated. Version 3 also includes enhancements that allow modeling of weirs/spillways, gates,
pipes, and pumps for highly engineered systems. Planned future enhancements include sediment transport, contaminants, zooplankton,
periphyton, macrophytes, and sediment diagenesis capabilities.

VI. Additional remarks
A search for CE-QUAL-W2 at http://www.google.com will generate hundreds of links to the model including model applications, journal articles, conference abstracts, and reports. Additionally, a number of GUI pre/postprocessors have been developed by others for free/fee for V2 (a web search at google.com will generate the relevant links). Several developers have or are planning to upgrade the GUI's to V3. V2 is still available for use on single lakes, rivers, reservoirs, and estuaries and can be obtained by e-mailing a request to Thomas.M.Cole@erdc.usace.army.mil
