Abstract:

Effluent diffusers are used to gain relief from end-of-pipe acute toxicity criteria in NPDES water quality-based discharge permitting. Regulatory agencies require that the dilution provided by a diffuser be demonstrated through field measurements and/or numerical modeling. It is important that field measurements yield an estimate of flux-averaged dilution so comparisons with numerical diffuser models can be made.
