Partial Depth Flow Blocking - Part 1
DSI has added a new capability to EFDC+ 10.1. This new capability allows the model to simulate partially blocked depths due to floating objects
Partial Depth Flow Blocking - Part 2
Lake Washington is a very deep lake that made conventional bridge construction difficult. To allow a traffic to cross the lake, a floating bridge was constructed.
New EEMS Feature Timely For Hurricane Season- 4 Weeks Until Release
EEMS10 now has the ability to simulate spatially and temporally varying fields, such as a wind or barometric pressure fields.
Things are only getting better with EEMS
The release of EEMS 10.1 is now just five weeks away. Thank you for joining us last week as we showed how using EEMS 10.1 you can create multiple simultaneous model views.
Magnuson Park Closed for High E. Coli Levels
Beaches and parks along Lake Washington provide a great environment for outdoor activities and relaxation for residents nearby.
EFDC in China
Paul Craig, DSI Chief Consultant, made a presentation looking at the development history of EFDC at the inaugural iSymWater conference in Beijing on 8 July, 2019. EFDC continues to be a key tool for water quality modeling in China.
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+
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.
