QUAL2K: A Model for River and Stream Water Quality
 Entry ID: EPA_QUAL2K

[ Update this Record ]

Summary
Abstract: QUAL2K (or Q2K) is a river and stream water quality model that is intended to
represent a modernized version of the QUAL2E (or Q2E) model (Brown and Barnwell
1987). Q2K is similar to Q2E in the following respects:

One dimensional. The channel is well-mixed vertically and laterally.

-Steady state hydraulics. Non-uniform, steady flow is simulated.

-Diurnal heat budget. The heat budget and temperature are simulated as a
function of meteorology on a diurnal time scale.

-Diurnal water-quality kinetics. All water quality variables are simulated
on a diurnal time scale.

-Heat and mass inputs. Point and non-point loads and abstractions are
simulated.
