QUAL2K: River and Stream Water Quality Model
QUAL2K (or Q2K) is a river and stream water quality model that is intended to rep-resent a modernized version of the QUAL2E (or Q2E) model (Brown and Barnwell 1987). The models are one dimensional and the channel is well-mixed vertically and laterally. It has Steady state hydraulics and is Non-uniform; its steady flow is simulated. The diurnal heat budget and temperature are simulated as a function of meteorology on a diurnal time scale. All diurnal water-quality kinetics are simulated on a diurnal time scale. It has heat and mass inputs. Its point and non-point loads and abstractions are simulated.
