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 3.7. The model release includes executables, source
codes, and examples for the W2 V3.7 model and preprocessor. There is also a
stand-alone V3.7 GUI preprocessor as part of the download package. There is a new post-processor for W2 for the V3.7 model by the DSI, Inc.
group and an Excel macro utility that aids the model user in writing out files compatible with CE-QUAL-W2. A model blog on updates and fixes is included below. Version 3.6 which is no longer supported is also
available from the download page.
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.
