In recent years, with the emergence of water environment problems, the surface water environment is not only the focus of public attention, but also the focus of environmental protection, water affairs and other departments. It has become a decisive factor in project approval, planning formulation, and even leadership assessment. In particular, the State Council’s water ten is about to be released, which will surely set off a new round of surface water environmental quality policy, planning, and scientific research. In order to quantitatively describe the dynamic relationship between surface water environmental quality and pollution discharge, numerical models such as EFDC, MIKE, Delft3D, and Qual2K are widely used in many fields such as environment, water affairs, and oceans. Environmental Fluid Dynamics Code (EFDC) is a general model package for simulating 3D flow, solute transport, and biochemical processes in rivers, lakes, estuaries, reservoirs, wetlands, and offshore surface water systems. The EFDC model was originally a public domain software developed by John Hamrick et al. of the Virginia Institute of Marine Science (VIMS), College of Oceanography, University of William and Mary (Hamrick, 1992). With the support of the U.S. Environmental Protection Agency (EPA), EFDC has become an important member of the recommended model family for the Total Maximum Daily Load (TMDLs), and is increasingly favored by domestic scientific researchers. EFDC is a free and open source numerical model with hundreds of related parameters. However, there are few introductions and examples related to EFDC at present, and even fewer Chinese books.
Dr. Qi: He has long been engaged in water environment simulation, surface water environmental impact assessment, sewage outlet setting demonstration and other related work, and has rich practical experience in EFDC application.
