Wastewater Field Thickness and Initial Dilution

Abstract

A method is proposed which can be used to couple the two phenomena of plume rise and gravitational spreading in obtaining an integrated solution to the mixing in wastewater plumes from multiple port diffusers. Explicit solutions are obtained for the special case of two‐dimensional pure plumes in either uniform or linear density profiles. These solutions are of practical importance in providing estimates of initial dilution for both design calculations and environmental monitoring purposes.
