Model
Description
CE-QUAL-W2
is a water quality and hydrodynamic model in 2D (longitudinal-vertical) for
rivers, estuaries, lakes, reservoirs and river basin systems. W2 models basic
eutrophication processes such as temperature-nutrient-algae-dissolved
oxygen-organic matter and sediment relationships. The current model release
enhancements have been developed under research contracts between the Corps and
Portland State University under supervision of Dr. Scott Wells.
The current model release is Version 3.6. The model release includes
executables, source codes, and examples for the W2 V3.6 model and preprocessor.
There is also a stand-alone V3.6 GUI preprocessor available for download.
Model
Capabilities: Longitudinal-vertical hydrodynamics and
water quality in stratified and non-stratified systems, multiple algae,
epiphyton/periphyton, zooplankton, macrophyte, CBOD, and generic water quality
groups, internal dynamic pipe/culvert model, hydraulic structures (weirs,
spillways) algorithms including for submerged and 2-way flow over submerged
hydraulic structures, dynamic shading algorithm based on topographic and
vegetative cover.
Model
Limitations: Well-mixed in lateral direction (but can be
used in a Quasi-3-D mode by use of additional model branches), hydrostatic
assumption for vertical momentum equation.
