Summary
Abstract:
QUAL2Kw is a river and stream water quality model that is intended to represent
a modernized version of the QUAL2E model (Brown and Barnwell, 1987). QUAL2Kw is
related to the QUAL2K model that was developed by Dr. Steven Chapra (Chapra and
Pelletier, 2003).
QUAL2Kw includes some processes and options that are not in QUAL2K. QUAL2Kw is
similar to QUAL2E in the following respects:
* One dimensional. The channel is well-mixed vertically and laterally.
* Steady state hydraulics. Non-uniform, steady flow is simulated.
* Diel heat budget. The heat budget and temperature are dynamically
simulated as a function of meteorology on a diel time scale.
* Diel water-quality kinetics. All water quality variables are dynamically
simulated on a diel time scale.
* Heat and mass inputs. Point and non-point loads and abstractions are
simulated.

Description:
The Models Knowledge Base is an inventory of EPA?s environmental models. It
contains information about model use (What are the requirements?, How can it be
obtained?, and How is it used?) and model science (What is the scientific basis
for the model?, How was the model developed?, and Was the model evaluated?).
The modeling community is encouraged to provide feedback about the Models
Knowledge Base and its models.
