Hydrodynamics and transport simulations were conducted with the modeling software TELEMAC-
2D on Icó-Mandantes bay, a branch of the Itaparica reservoir. The bay has a maximal operational
water level amplitude of 5 m and is suffering from eutrophication and algae bloom. Therefore, we
investigated low and high water level scenarios with two different high resolution meshes, with the
purpose to deeper understand their impact on transport of substances and to improve the
watershed management. In particular, nutrient emissions from a hypothetical net cage aquaculture
system located in the bay were investigated on half-year cycles. We observed a relevant impact on
water quality for a tilapia production of 130 t y-1; i.e. after 6 months’ simulation we obtained
around 8 μgP L-1 and 6 μgP L-1 at the source of emissions, for low and high water scenarios,
respectively. |
