Description A water quality modeling study of the Snohomish River Estuary system from Possession Sound to river mile 20 was conducted using an Environmental Protection Agency supported water quality simulation program (WASP5) model to simulate hydrodynamics and water quality. The WASP5 model was developed to assess the capacity of the estuary system to assimilate oxygen consuming pollutants from point and nonpoint sources. The model was calibrated using data collected in August and September 1993 and confirmed (verified) using data collected in August 1996.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
