Environmental & Water Quality Operational Studies. Evaluation of Selected One-Dimensional Stream Water-Quality Models with Field Data.
Abstract
Evaluation of the U.S. Geological Survey One-Dimensional Steady-State Stream Water-Quality Model (a modified Streeter-Phelps model), the QUAL II model (Southeast Michigan Council of Governments version), and the U.S. Army Hydrologic Engineering Center's Water Quality for River-Reservoir Systems model indicate that these readily available models for simulating water quality downstream of reservoirs were of comparable accuracy and performed according to their documentation. The evaluation was based on a wide range of accurate steady-state data collected on the Chattahoochee River in Georgia, the Willamette River in Oregon, and the Arkansas River in Colorado. A number of differences exist among these three models; each model has the flexibility to make these differences relatively unimportant for typical water quality studies. Each model had minor coding errors which have been corrected. Modeling capabilities are summarized in tabular form to facilitate comparison and selection. Although the modified Streeter-Phelphs and QUAL II models are equally valid, different modeling options may amke one preferable depending on the specific modeling application. (Author)
