In this study, enhancements to the numerical representation of sluice gates and turbines were made to the hydro-environmental model Environmental Fluid Dynamics Code (EFDC), and applied to the Severn Tidal Power Group Cardiff–Weston Barrage. The extended domain of the EFDC Continental Shelf Model (CSM) allows far-field hydrodynamic impact assessment of the Severn Barrage, preand post-enhancemen...

Cost-effective implementation of microalgae as a solar-to-chemical energy conversion platform requires extensive system optimization; computer modeling can bring this to bear. This work uses modified versions of the U.S. Environmental Protection Agency's (EPA's) Environmental Fluid Dynamics Code (EFDC) in conjunction with the U.S. Army Corp of Engineers' water-quality code (CE-QUAL) to simulate...

This paper presents a methodology for using hydrodynamic modeling to estimate inundation areas and water depths during a hurricane event. The Environmental Fluid Dynamic Code (EFDC) is used in this research. EFDC is one of the most commonly applied models to Gulf of Mexico estuaries. The event with which the hydrodynamic model was tested was hurricane Ivan. This hurricane made landfall at the A...

In this study, SEDDEER (Sediment Deposition and Erosion), a stand-alone sediment and contaminant model which simulates one water box and the underlying multiple sediment bed layers, was incorporated into Water Quality Analysis Simulation Program (WASP7.4). WASP7.4 toxic module (TOXI7) was modified to include SEDDEER to develop WASP_SEDDEER model. Tests were designed to ensure that the coupling ...

This paper presents a comparison of two hydrodynamic models of the Weeks Bay sub-estuary (Alabama, USA). One model was developed using the Environmental Fluid Dynamic Code (EFDC). The resulting model was compared to an existing hydrodynamic model (of the same water body) that was developed using the Adaptive Hydraulic modeling system (ADH). Comparisons were performed in terms of predicted water...

the johor strait is an estuarine system located on the coast of the state of johor in malaysia.the western part of johor strait is a shallow estuarine located between causeway and pulai river. ahydrodynamic model was calibrated based on the environmental fluid dynamic code (efdc) from 4th to 17th of october, 2009. in this calibration, the efdc hydrodynamic model was configured to simulate time ...

Water-quality model simulation is the key to understanding hydrological processes and water-quality dynamic(s). In this study, Jingpo Lake, which most typical lake in northern cold region of China, was selected as research object. A numerical for transporting diffusing chemical oxygen demand (CODMn) ammonia nitrogen (NH3N) with ice-covered open-water periods constructed calibrated using Environ...

Laguna Lake is one of the widely used fresh water source in Metropolitan Manila. Numerous studies have been conducted for the water quality monitoring of the lake. Large amounts of pollutants are continuously received by the lake from domestic, industrial and others sources. The physical appearance of the lake alone needs attention. Physical characteristics of water include depth, flow velocity...

Green algae play an important role in ecosystems as primary producers, but they can cause algal blooms, which are socio-environmental burdens responding to them requires water resources from dam reservoirs. This study proposes alternative for reducing blooms through operation without using additional resources. A novel oscillation flow concept was suggested: oscillating discharge of irregular f...
