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
