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. Among the findings, researchers….
Lake Washington Sigma-Zed Application
Lake Washington is second largest natural lake in the State of Washington, USA. It is lake with steeply sloping sides and also has long-term, high quality vertical temperature records. This makes it an ideal case to test the Sigma-Zed layering approach. DSI developed a hydrodynamic model of this water body with 1,183 cells and 55 layers to assess the accuracy for prediction of the epilimnion and hypolimnion.
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….
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. EFDC modeling studies have indicated that water level drawdown plays an important role in thermal stratification and water movement of Lake Mead during receding water levels (Li, 2010).

West Lake Real-time Hydrodynamic and WQ Model
DSI has recently developed a demonstration real-time model of West Lake, Hanoi. Input data snd simulation results from the EFDC hydrodynamic and water quality model may be viewed on-line at the link provided below. More Info
Pearl Harbor Model Development
DSI recently completed development of an EFDC model of the Pearl Harbor, Hawaii. We supported Sea Engineering International in this work, which will simulate the transport and deposition of suspended sediment caused by the dredging. The model accurately reproduces the flow dynamics inside and outside of Pearl Harbor and will be used for a planning…
Velocity Post Processing – Part II
Did you know that EFDC_Explorer has a Downstream Velocity Projection feature? This feature allows the user to specify an orientation angle (degrees clockwise from north, looking downstream) …
Velocity Post Processing – Part I
Did you know that EFDC_Explorer has a Velocity Rose feature? This feature allows the user to view the speed and direction distribution of a given cell over a user defined period of time….
“Warm Start” function
Did you know that EFDC_Explorer has a “Warm Start” function that allows you to create the initial conditions for the model at a specified time. This is useful for diagnostic and sensitivity analyses….
A context specific menu for hot-key actions
Did you know that EFDC_Explorer has a context specific menu for hot-key actions that can be accessed with the “F2” key?
Dragging and dropping project files into EE
Beginning with EFDC_Explorer 6, users have the ability to open projects by dragging and dropping project files into EE….
