Using EEMS to Model the Effects of Sediment Dredging
Dredging refers to excavating sediments under a water body. The purpose for each dredging operation varies…
High-Resolution Marine Cadastre AIS Data for Propwash Modeling
Propeller wash (propwash) causes sediment scour in the seabed that can threaten the safety of structures….
Coupling HSPF Water Quality Model with EFDC+
Developing a hydrodynamic or a water quality model may require input of boundary conditions from other models…
Kingston Ferry Terminal Propwash Simulation
Kingston Ferry Terminal Propwash Simulation Sediment erosion caused by propeller wash from ships is of considerable…
Lake Washington Real-Time Model
DSI recently developed a real-time model for Lake Washington, along with a public-access model portal…
JSON Formatted Files in EEMS
JSON (JavaScript Object Notation) is an increasingly common standard data format to store and transmit data objects that us…
Enhancements to the EEMS GUI
As we added new features to EFDC+, our Graphical User Interface (GUI), EFDC_Explorer (EE) has also changed to…
Modeling Interaction Between Phytoplankton and Zooplankton in EEMS
Zooplankton population modeling is a significant new feature in the recently released version of …
Transforming Node Time Series Model Result to EE Field File
There can be multiple reasons when a modeler needs to incorporate results from another model. It can be the lack of direct measurement of specific properties or…
Testing EFDC+ Propeller Wash Module with Sediment Transport Process
This post introduces a simple testing process to demonstrate how the propeller wash module works with EFDC+’s sediment transport process modeling features.
NetCDF-CF and UGRID Formats
The Network Common Data Form (NetCDF) data format was originally intended to create, access, and share array-oriented data in a form that is self-describing and portable…
Creating Great Animations in EEMS
Communicating your modeling results to a wide variety of audience is as important as developing a good model. Animating the processes is one of the most powerful ways in which a modeler…
Simulating Wind-Induced Waves in EEMS
Wind-induced waves affect the propagation of gravity waves. Wave modeling hindcast is a critical step for wave energy development and…
Propeller Wash
Cleanup of contaminated sediment sites may include dredging, capping, or in-situ treatment, or a combination of these three techniques. Long-term stability of sediments is key to the success of these remedial actions…

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.
