The latest EFDCPlus/EFDC_Explorer Modeling System, version EE8.2, has now been released. This update of DSI’s hydrodynamic, sediment transport and WQ modeling tool comes with enhancements to better support Sandia National Lab’s developments to EFDC, namely the SEDZLJ sediment transport model, and the Marine & Hydrokinetics module, and much more.
Alberta Environment and Parks recently awarded DSI the contract for a hydrodynamic and water quality model of the upper Little Bow River main stem, including the Twin Valley Reservoir, and its tributary Mosquito Creek. DSI is using EFDC for the set-up, calibration, validation and implementation of this in-stream water quality model.
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….
This past weekend, a major fish die-off occurred in West Lake, the largest freshwater lake located in Vietnam’s capital of Hanoi….
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 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.
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 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).
Most people who read to obtain information prefer to have the text supplemented with visuals. The advantages of 2D and 3D data visualization are numerous. Aside from effectively summarizing….
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….
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
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…
