The manual is a major revision of the original QUAL2E program documentation released in 1985. It includes a description of the recent modifications and improvements to the widely used water quality models QUAL-II and QUAL2E. The enhancements include an extensive capability for uncertainty analysis with the QUAL2E-UNCAS model, an option for reach-variable climatology input for steady-state temperature simulation, and an option for plotting observed dissolved oxygen data on the line printer plots of predicted dissolved oxygen concentrations. QUAL2E, which can be operated either as a steady-state or as a dynamic model, is intended for use as a water quality planning tool. QUAL2E-UNCAS is an enhancement to QUAL2E that allows the user to perform uncertainty analysis.
