Abstract: The fate and transport of the fine suspended particulate (floc) discharged within the effluent of a proposed pulp mill plant in Tasmania, Australia is investigated. Through a range of ad-hoc physical modelling laboratory experiments we determined: particle size distribution (1 to 100 μm) under different level of turbulence, settling rates (1 to 3 mm/s) and critical bed shear stress for resuspension (0.006 N/m2). The aim of the investigation was to track by physical simulation the suspended floc throughout its dynamic transport cycle through the discharge pipe and in the marine receiving environment within the near-field zone, including settling and re-suspension dynamics.
