Abstract The mathematical water quality model QUAL-II was modified to reflect advances in the understanding of algal, nutrient, and light interactions. Code changes also were made to incorporate hydraulic, boundary condition, water quality constituent, and rate coefficient features that had utility in other steady state water quality models. The new model provides an increased number of simulation options and a comprehensive output format designed to aid in calibration and verification.
