AEE has established high reputation in software development and training, including:
¡¡
| EFDC |
The EFDC model is a public-domain modeling package for simulating three-dimensional flow, transport, and biogeochemical processes in surface water systems, including rivers, lakes, estuaries, reservoirs, wetlands and coastal regions. In addition to hydrodynamics, salinity, and temperature transport simulations, EFDC is capable of simulating cohesive and noncohesive sediment transport, near field and far field discharge dilution from multiple sources, eutrophication processes, and the transport and fate of toxic contaminants in the water and sediment phases. The EFDC model has been tested and documented in more than 100 modeling studies, and is currently used by universities, governmental organizations, and private industries. |
| BASINS | BASINS (Better Assessment Science Integrating Point and Nonpoint Sources) is a multipurpose environmental analysis system designed for use by regional, state, and local agencies in performing watershed and water quality-based studies. This system makes it possible to quickly assess large amounts of point source and non-point source data in a format that is easy to use and understand. Installed on a personal computer, BASINS allows the user to assess water quality at selected stream sites or throughout an entire watershed. This invaluable tool integrates environmental data, analytical tools, and modeling programs to support development of cost-effective approaches to watershed management and environmental protection, including TMDLs. |
| HSPF |
HSPF (Hydrological Simulation Program) is a comprehensive, conceptual, continuous watershed simulation model designed to simulate all the water quantity and water quality processes that occur in a watershed, including sediment transport and movement of contaminants. Although it is usually classified as a lumped model, it can reproduce spatial variability by dividing the basin in hydrologically homogeneous land segments and simulating runoff for each land segment independently, using different meteorologic input data and watershed parameters. The model includes fitted parameters as well as parameters that can be measured in the watershed. |
| WASP | WASP (Water Quality Analysis Simulation Program) helps users interpret and predict water quality responses to natural phenomena and manmade pollution for various pollution management decisions. WASP is a dynamic compartment-modeling program for aquatic systems, including both the water column and the underlying benthos. WASP allows the user to investigate 1, 2, and 3 dimensional systems, and a variety of pollutant types. The state variables for the given modules are given in the table below. The time varying processes of advection, dispersion, point and diffuse mass loading and boundary exchange are represented in the model. WASP also can be linked with hydrodynamic and sediment transport models that can provide flows, depths velocities, temperature, salinity and sediment fluxes. |
| SEAWAT | SEAWAT is a computer program that couples tow popular programs, MODFLOW and MT3DMS for flow with variable density in porous media. It is a useful tool especially for the study of the saltwater intrusion problems along the coastal areas. |
| MODFLOW | MODFLOW is the most popular computer program used for simulation of groundwater flow. The code was developed by the U. S. Geological Survey. AEE has conducted two MODLFOW training classes in China: MODFLOW document has been translated into Chinese by AEE employee and published by the U. S. Geological Survey. |
| MT3DMS | MT3DMS is a new version of the Modular 3-D Transport model, where MS denotes the Multi-Species structure for accommodating add-on reaction packages. MT3DMS has a comprehensive set of options and capabilities for simulating advection, dispersion/diffusion, and chemical reactions of contaminants in groundwater flow systems under general hydrogeological conditions. |
