Application of a Near-Field Water Quality Model.

Abstract

A two-dimensional near-field water quality model has been developed to describe the behavior of effluents dominated by jet mixing. Verification against data is good and demonstrates the model's utility and reliability. It can be employed as a planning and assessment tool for water quality studies. The model provides the ability to assess localized impacts in excess of that shown by the usual one-dimensional models. The primary limitations of the model are: 1) the model is invalid for cases where vertical mixing is significant; 2) the model does not deal well with highly buoyant discharges; 3) the model does not account for the existence of solid boundaries; 4) the model may become invalid before the one-dimensional region is reached, requiring the use of a diffusion model to carry the calculations further downstream.
