In the News: Spencer Dam Failure
Early in the morning on March 14, 2019, the 92-year-old Spencer Dam located on the Niobrara River in Nebraska failed due to a combination of ice accumulation and high flows.
Ask The Experts: Sediment Transport Modeling
For sediment transport modeling, EFDC requires a modeler to define particle size classes and specify the median diameter for each class, which can represent the average behavior of the particles.
In the News: Algae Bloom off the Coast of Florida
In case you are lucky enough to be missing the recent cold snap that has passed the US by, here is some “cool” time-lapse footage of the impact of wind and cold weather on Lake Michigan.
In the News: Taylor Oil Spill in the Gulf of Mexico
The United States is quickly becoming the world's largest oil producer, a significant component of this increased production capacity is related to an expansion of offshore oil drilling.
Ask the Experts: What is the correct wind direction convention to use in EFDC?
While the standard meteorological convention for the wind direction is the compass direction that the wind is coming from (direction from), in EFDC the standard convention is the compass direction that the wind is going towards (direction towards).
Industrialization's Effect on the Yellow Sea

Han River Development
There's no doubt the waterways of Europe are tourist attractions in themselves, drawing millions to stroll the banks of the River Thames in London and the River Seine in Paris every year.
The History of Hydrodynamic Studies
This is the first in a three-part blog series that provides an introduction to hydrodynamic modeling, an overview of how models work, and, finally, an exploration of their many applications.
EFDC+ vs. Other EFDC Versions
The Dynamic Solutions International (DSI) version of EFDC is called EFDC+ (formerly EFDC_DSI). EFDC+ is one of the most used versions of the EFDC model available to the scientific and engineering community.
West Lake Fish Die-Off
This past weekend, a major fish die-off occurred in West Lake, the largest freshwater lake located in Vietnam's capital of Hanoi.
EFDC+ Explorer and the Future of Hydropower
The U.S. Department of Energy has the answer with its recently released forecast and roadmap for hydropower from the present to the year 2050.
Lake Washington Sigma-Zed Application
Lake Washington is the second largest natural lake in the State of Washington, USA. It is a lake with steeply sloping sides and also has long-term
Sigma-Zed Model in EFDC+
This new version of the code is called the Sigma-Zed code (SGZ) and has been integrated into the EFDC+.
Sigma-Zed Model in EFDC+
DSI has developed an improved version of the EFDC code to help deal with pressure gradient errors that occur in simulations that have steep changes in bed elevation. This new version of the code is called the Sigma-Zed code (SGZ) and has been integrated into the EFDC+
Lake Mead Sigma-Zed Application
Lake Mead is the largest reservoir in the USA, and 16th largest man-made lake in the world. Lake Mead is formed by the Hoover Dam along the Colorado River.
Subscription or Perpetual Licensing
In the old days, when you purchased software, there was a tangible element: You received a package of one or more floppy disks or CD-ROMs, which you then used to install the software.
