Abstract : A one-dimensional reservoir water quality model, CE-QUAL-R1, is currently being developed for use by U.S. Army Corps of Engineers District and Division Offices. Tests are needed which will ensure that model predictions are satisfactory. Although the literature contains much information concerning model evaluation, there is little agreement among authors concerning specific tests. Two general types of tests are proposed. The first group of tests are used to ensure that the coding of the model is correct, and the second group to ensure that the model predictions are suitable for the needs of the Corps. The latter tests include both qualitative and quantitative comparisons of model predictions with field-measured values. It is argued here that a thorough model evaluation must include comparisons of fluxes between variables, as well as comparisons of the mass or concentrations of variables.
