Table 2.1.1 Selected Water Quality Models
Waterbody
Model
Description
River
STEADY
1-D longitudinal steady-state, temperature, DO, and BOD
QUAL2E
1-D longitudinal steady flow stream water quality model
(EPA).
FLUX
1-D loading model
CE-QUAL-RIV1
1-D dynamic flow, time-varying stream hydraulic (RIV1H)
and water quality (RIV1Q) models.
TWQM
Tailwater Quality Model, 1-D steady flow, steady-state
stream water quality model for reservoirs and tailwaters.
Includes reduced substances (e.g. iron, manganese, and
sulfides).
Reservoir
PROFILE
1-D vertical 2 layer (mixed upper layer and hypolimnion)
steady-state model, calculates oxygen deficit rates.
BATHTUB
1-D longitudinal 2 layer (mixed upper layer and hypolimnion)
steady-state empirical eutrophication model.
CE-THERM-R1
1-D vertical reservoir model for temperature.
CE-QUAL-R1
1-D vertical reservoir model for water quality.
WESTEX
1-D vertical reservoir model for temperature and conservative
constituents.
CE-QUAL-W2
2-D laterally-averaged, longitudinal, vertical, hydrodynamic
and water quality model for reservoirs, estuaries, and other 2-
D water bodies.
SELECT
1-D vertical, steady-state model for predicting the selective
withdrawal outflow distribution and release concentrations
for reservoir outlets.
Others
HEC-5Q
1-D vertical (reservoir) and 1-D longitudinal (stream)
reservoir systems operation model that includes water
quality.
CE-QUAL-ICM
1-D, 2-D, and/or 3-D water quality model. Must be linked to
hydrodynamic model output.
RECOVERY
Zero-Dimensional (water column) PC based screening model
to assess the impact of contaminated bottom sediments on
surface waters. The bottom sediments are modeled with 1-D
vertical layers.
