This document outlines the advection-dispersion model used to quantify the dynamics of the treated wastewater plume discharged from the Wastewater Treatment Plant south of Titahi Bay at Kaumanga Point. 

It provides details of field data carried out for the study, a review of monitoring data used to calibrate the model, an overview of the hydrodynamics of the area offshore of the discharge and results from long-term model simulations.
