EFDC+ now uses a hybrid MPI/OMP domain decomposition approach for vastly improved model run times. Using cluster systems, this approach can be scaled up to run as much as 25 times faster than other approaches. MPI enables you to run models faster than ever before to meet tight project deadlines while maintaining performance.
Develop robust and defensible numerical solutions for complex hydrodynamic and water quality problems with this leading-edge computational model.
Fully Coupled Model
Save time and avoid mistakes with a fully coupled model. No external linkages are required between the hydrodynamic model and other sub-models. Sediments, toxics, or water quality sub-models are all natively linked for improved speed and performance.
Maintained & Supported
Unlike many versions of the EFDC code, EFDC+ is centrally maintained and supported. This means that you have one go-to source for code improvements and reporting any bugs you think might be in the code. We fix them and release updates to our active users.
SEDflume Sediment Model
As part of EFDC+, you can use Sandia National Laboratory’s state-of-the-art SEDZLJ sediment transport sub-model, which incorporates site-specific erosion rate (SEDflume) and shear stress data, while maintaining a physically consistent, unified treatment of bedload and suspended load. The model has now been further enhanced to support toxics.
