Simulating Biota in EFDC+
Water quality simulation in waterbodies involves the biochemical transformation of the nutrients, their movement through several water layers….
Velocity Profile of a Propeller moving through a Channel
In this post, we would like to demonstrate how the propeller transfers the energy to the water column causing sediment resuspension.
Propeller Wash Simulation Using Historical Ship Track Data
Simulation of the impacts of propeller wash in hydrodynamic and sediment transport models requires detailed information on ship travel routes and the physical characteristics of each ship.
The Importance of Propeller Wash Modeling
Many urban waterfronts are contaminated with metals, petroleum hydrocarbons, and other organic chemicals. The contamination could be as much as 20 feet…
Modeling Climate Change Impacts Using EE
Climate change is an accepted reality, so most infrastructure development and maintenance will require the evaluation of possible impacts of climate change.
Modeling Sediment Resuspension in a Coastal Environment Due to Ship Traffic
Sediment resuspension occurs in harbors across the world as a function of propeller-induced water velocities, and resulting shear stress, at the sediment-water interface. While such events occur with….
Simulation of Manatee Habitat with EEMS
The warm waters and shallow, vegetated waterways of the Gulf of Mexico provide valuable habitat to a diverse range of plants and animals….
EFDC+ with Hydrologic Simulation Program-Fortran (HSPF)
As part of DSI’s committment to the scientific and modeling community, DSI is now providing a template script that modelers can use to run an HSPF model, process the output, run the EFDC+ model, and plot the output.
Fortran – A Language for Engineering and Scientific Computing
With so many new computer languages available today, a question often asked is, “Why is EFDC+ coded in Fortran language?”
Generating Field Files for EFDC+ from External Data using Python
EFDC+ support input of spatially and temporally varying boundary conditions as field files, which means user can assign…

Following the release of EEMS10.2, the DSI Team is busy developing exciting new features for the next version of EEMS….
Webinar: Increasing the Performance of EFDC+ Models using Domain Decomposition
Join Mr. Paul Craig, the chief developer of EFDC+ and EEMS to learn how domain decomposition and MPI can help speed up your EFDC+ model.
Shellfish Farm Module in EEMS10.2
EEMS from version 10.2 onwards will include a Shellfish Farm Module. This module incorporates a modeling approach….
Implementation of Domain Decomposition in EFDC+ Using MPI
A primary function of EFDC+ is to solve the governing Partial Differential Equations (PDEs) for fluid flow and…
EFDC+ v10.2 MPI – Benchmark Test
The MPI implementation in EFDC+ offers a significant improvement in run time compared to the OMP versions of EFDC+.
