EFDC+ Release Notes

Enhancements

• COARE 3.6 Integration: COARE is one of the most frequently used algorithms in the air-sea interaction community to predict surface temperatures. It is designed to give estimates of the turbulent fluxes of sensible and latent heat and the stress from measurements of bulk variables such as water temperature, air pressure, and specific humidity. With the release of EEMS 12.1, the Environmental Fluid Dynamics Code Plus (EFDC+) will allow users to simulate these fluxes by incorporating the COARE subroutines. You can learn more about the implementation of this feature in our introductory blog post. In this more recent blog post, we have also demonstrated that the algorithm can be applied in freshwater bodies such as Lake Mendota.
• Vertical Layering Enhancements: A new vertical layering option following the Sigma-Zed (SGZ) approach has recently been added to EEMS. The new SGZ scheme allows the user to specify layer thickness in meters from the water surface. Itoffers significant flexibility in configuring the vertical layering system, complementing the existing options, including the original Sigma Stretch (SIG) and the current Sigma-Zed (SGZ). Learn more about these changes by reviewing this blog post or reading the Knowledge Base.
• Volatilization Option: When simulating chemical fate and transport, volatile chemicals at the air-water interface frequently off-gas from the water into the atmosphere. The Chemical Fate module in EEMS is designed to work primarily in conjunction with the Sediment module, as the toxic substances sorb to sediments. In cases where sediment data is sparse or missing altogether, using a dye class as a proxy for the dissolved chemicals is recommended. To help users more accurately simulate this case, a volatilization component has been added to the dye proxy. To learn more, read this blog post or the EFDC+ Theory Document.
• 3 Time Level Scheme Updates: A number of improvements have been made to the 3 Time Level (3TL) computational scheme. This numerical solution option is often more stable and faster than the 2 Time Level (2TL) scheme since it allows a larger computational time step. However, the 3TL scheme was not fully implemented in the original EFDC from Hamrick. DSI has refactored the code for the application of parallel computing using OMP-MPI. DSI has also fixed several bugs in the code so that 3TL has now become our favored solution option for hydrodynamic models.
• NetCDF Updates: EFDC+ has recently been integrated into studies as part of the Delft-Flood forecasting and Early Warning System (FEWS) platform. Delft-FEWS is open software using a modular framework to link big data to a local area or from other modeling systems. In this study, EFDC+ was required as one of the modules, and the NetCDF capabilities were required to be updated to the latest convention to allow seamless integration. Some of the improvements for EEMS 12.1 include:
  • Upgraded NetCDF CF Conventions 1.4 to 1.11
  • Upgraded to UGRID 1.0 Conventions
  • Fixed standard names and units according to NetCDF CF Conventions 1.8 checker
