EFDC+ Explorer
Enhancements
- EE can now access ship info from the “EEMS Ship Database”
- Improved the propeller wash module layout to make it more user-friendly
- Updated the propeller wash HTML reports.
- Added the capability to export the Habitat Module HSC maps to shapefiles.
- Improved the presentation for the Sediment Bed parameter list in the “2DH View Option” form
- Updated the Oil parameters, including group ID and the precision format for DRIFTERS.INP
- Changed “High frequency” to “Entire Domain” in the “EFDC Model Linkages” form.
Bug Fixes
- When a user set values in the “Contour Settings” form, it would reset after moving the time control or animation.
- The initial condition RPEM values were not displayed correctly in the 2DH view after setting them for the “Spatially Varying” option in the “EFDC Rooted Plant And Epiphyte Algae Model” form.
- Failed to use the Wind speed conversion factor when reading WSER.INP.
- Column index not saved when importing the wind time series data.
- When importing the wind time series data, the user defines the index of the column for wind speed and wind direction by clicking Multiple Column and then clicking the OK button. However, when clicking the Multiple Column button again, the fields that were chosen previously disappeared. EE now remembers the user selection until the user changes it.
- In the “SEDZLJ Sediment and Sediment Bed Properties” form, after entering a value in the cell, the font size increased after pressing the Enter key.
- Labels of River Mile (Creek Mile), sets the interval to 0.1 miles, but the label displayed too many decimal points.
- The timing values in the “Simulation Timing Options” form changed unexpectedly
- SEDSTART precision in BED.SDF and C37 of EFDC.INP was not consistent.
- The PBIAS calculation in EE11.4 and earlier was incorrect. The calculation now compares every paired data value in the time series, instead of the overall average.
EFDC+
Enhancements
- Added “fast settling” sediment classes during propwash erosion events. The fast settling classes reflect the process of mass erosion due to a more turbulent and energetic flowfield in the propwash plume. These mass eroded sediments then behave differently in the water column than the original sediment classes, predominantly by reflecting a faster settling rate than the original sediment classes. The addition of the fast settling classes and the fate and transport of these sediments is dynamically handled by EFDC+. The fast settling classes are fully integrated into the toxics transport of EFDC+.
- Added two new open boundary condition types. A free tangential and a zero tangential anti-reflection boundary condition were added to improve the propagation of waves out of the model domain without reflecting off the open boundary.
- Improved the zero tangential and free tangential radiation boundary conditions previously in EFDC+ to handle non-zero average tidal levels.
- Added capability of macrophyte growth between layers and for the base of the macrophytes to be in any layer. Allows for floating macrophytes to start at the surface and drape down into the water column.
- Added more detail to the executable logging for the efdc+ output files
- Limit the withdrawal layers to only active layers. This check was needed because the Sigma-Zed vertical layering approach can use different numbers of layers per cell.
- Removed duplicate timing variables ISTL_ and IS2TL_ from all subroutines. These variables were available in the global module.
- Disabled horizontal eddy diffusivity and viscosity for large aspect ratio cells on the open boundary.
- Improved reporting of ice generation limitations when cells are shallow and/or dry.
- Added more checks for toxic bed initial conditions.
Bug Fixes
- Fixed issues with multiple toxics using multiple OpenMP threads. Now when using multiple threads or single threads, the toxic calculations are reproducible.
- Fixed water quality mass loading when using withdrawal flow conditions as the original mass loading approach for water quality state variables did not address withdrawals.
- Forced dry cells to be wet for point source loading inflows.
- Fixed a bug for converting groundwater inflow time series from input units to cubic meters per second.
- PSMLMULTIPLIER was added to the mass loading option to correct for 3TL solutions. Historically, the mass loading for 3TL was underestimating loads due to the trapezoidal correction. For 2TL solutions, the PSMLMULTIPLIER is = 1.0, but for 3TL solutions, PSMLMULTIPLIER is adjusted for the number of steps between the corrector step.
Tools - EEMS-BASINS Plugin
This EEMS plugin for BASINS exports a BASINS model and creates a grid and hydrodynamic model in EEMS. The download includes a pdf file with instructions for installation and use. We have also made a detailed video demonstration that outlines the steps starting from building a watershed model in BASINS with Lake Mendota. Anurag Mishra, one of the BASINS developers, walks us through this process in the video.
Understanding EEMS Version Numbers
DSI now provides a stable and an edge release version of EEMS. We will provide only GUI bug fixes to the stable version and not add any new features, or make changes to the computational engine.
Edge release will include minor enhancements, features, and fixes to both the GUI and computational engine (EFDC+).
The naming system works in such a way that the second number, 10.x.0 represents, at minimum, a change to EFDC+, and the third number 10.3.x represents a fix to EE.
Details of all of the improvements for EFDC+ Explorer and EFDC+ can be found in these links.
