Challenges with Intake Analysis
Engineers often need to consider a range of layouts for hydropower intake design. The optimal design can depend on a range of factors including the type, number and location of intake structures.
Solutions Provided by EEMS
EEMS allows various design alternatives to be accurately modeled for shear stress, velocity and depth to arrive at the best solution. New hydrodynamic options may be built rapidly and model outputs analyzed efficiently, providing the decision makers with a variety of graphical outputs with which to make an informed assessment.
Examples of Studies Done with EEMS
NG Dam Safety Study Hydraulic Analysis for Emergency Response Plan (Laos)
The Nam Gnouang (NG) Dam, Bolikhamxai Province, Laos, is built on a major tributary of the Nam Theun/Kading river system, and located approximately 27 km upstream from the first Theun-Hinboun (TH) Diversion Dam, and 9 km upstream of the confluence. The reservoir behind the dam extends approximately 40 km upstream, and covers 105 square km at full storage. The dam is operated by the Theun-Hinboun Power Company (THPC). DSI performed a hydraulic analysis for failure on the NG Dam as part of the Theun-Hinboun Expansion Project (THXP) of the THPC

Use EFDC+ Explorer (EE) and EFDC+ to simulate hydrodynamics of a waterbody when time or water level controlled sluice gates or pumps are added. There are four models in this folder: 01_Uncontrolled, 02_Sluice_Time_Series, 03_Sluice_Control_Rules, 04_Pump, whose distinctives are described further below.
This model demonstrates the EFDC+ capabilities for hydraulic structures with the sluice gate option.
