“…The EFDC is an integrated modeling system that has been widely used for a wide range of environmental studies including simulating hydrodynamics, thermal stratification, water age, transport, Langrangian particle tracers and eutrophication processes in rivers, lakes, estuaries, reservoirs, wetlands and coastal regions (Çalışkan and Elçi, 2009;Gong et al, 2009;Hamrick, 1992;He et al, 2011;Li et al, 2009a;Li et al, 2013). The hydrodynamics of the EFDC is based on the Princeton Ocean Model (Blumberg and Mellor, 1987). The mass balance equation for each of the water quality state variables in the EFDC may be expressed as (Wu and Xu, 2011):…”
