Flood dynamics of large lake floodplain systems are typically complex. This paper analyses the characteristics and factors that influence the hysteresis of water area–stage curves for Poyang Lake, the largest freshwater lake in China characterized by complex geomorphology and upstream–downstream exchange conditions. For this purpose, a two-dimensional hydrodynamic model (EFDC) based on seven sc...

in order to achieve more effective management and monitoring of water environment, an automatic system is designed for the environment Heihe River Basin Zhangye through GIS (geographic information system). The EFDC (environmental fluid dynamics code) model used establish annual average data permanganate index Yingluoxia, Gaoya hydrological station, Liubaqiao from 2015 2019 are fit verify qualit...

Accidental oil spills not only deteriorate biodiversity but also cause immediate threats to coastal environments. This study quantitatively investigates the initial dispersion of spilled using environmental fluid dynamics code (EFDC) model, loosely coupled with an endorsed spill model (MEDSLIK-II) accounting for time-dependent advection, diffusion, and physiochemical weathering surface slick. F...

The purpose of this study is to investigate the effects of the wind drift factor under strong tidal conditions in the western coastal area of Korea on the movement of oil slicks caused by the Hebei Spirit oil spill accident in 2007. The movement of oil slicks was computed using a simple simulation model based on the empirical formula as a function of surface current, wind speed, and the wind dr...

In this study, the Mudan River, which is the most typical river in the northern cold region of China was selected as the research object; Environmental Fluid Dynamics Code (EFDC) was adopted to construct a new two-dimensional water quality model for the urban sections of the Mudan River, and concentrations of COD(Cr) and NH₃N during ice-covered and open-water periods were simulated and analyzed...

In this study, the water quality change in a stagnant controlled river containing hard management structures due to pulsed flow was simulated. The Environmental Fluid Dynamics Code (EFDC) model used for simulation, and improvement effect caused by simulated multiple scenarios. Based on Case 1, which 274.2–291.8 CMS discharged five hours, other scenarios, gate opened 0.5 m 1.0 while discharge ti...
