Abstract
The present study focuses on understanding the transport and fate of dissolved waste from aquaculture pens in near-coastal environments using the hydrodynamic code SUNTANS, which employs unstructured grids to compute flows at very high resolution. We perform simulations of the dissolved waste field and study the effects of different flow conditions (tides and currents) on the evolution of the waste plume. The fish pen causes partial blockage of the flow, leading to the deceleration of the approaching flow and the formation of a downstream wake. Results of the concentration field for an oscillatory flow condition superimposed on a mean current are presented and compared with the concentration resulting from a unidirectional flow field. The simulation results highlight the complex (and different) circulation patterns that occur around a submerged fish pen under oscillatory flow conditions and provide an understanding of the impact of aquaculture fish pens on coastal water quality. © 2009 ASCE.
