Oil spill patterns detected from Envisat ASAR images were integrated with hydrodynamic and oil spill trajectory models for the purposes of understanding the August 11, 2006 M/T Solar 1 oil spill, and to evaluate the accuracy of the oil spill patterns simulated by an oil trajectory model. The oil spill incident event that occurred a few kilometers southwest of Guimaras Island in Panay Gulf and I...

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...

Vectorized isosurface mapping is critical for conducting scientific research in computational fluid dynamics (CFD). We provide a Python-based tool the vectorized of scalar field information CFD simulation results, with goal reducing file size while ensuring editability and graphical presentation independent resolution. The ideal interpolation angle first determined by spatially rotating target ...

Floating treatment wetlands (FTWs) are widely used in surface water. The nutrient removal performance depends on both physical processes and chemical/biological transformations FTWs. However, research describing the coupling of hydrodynamic water quality system remains limited. Therefore, a coupled three-dimensional model for FTWs was developed based Environmental Fluid Dynamics Code (EFDC). Ad...

A number of hydraulic structures have been installed along the Yeongsan River, including an estuary dam and two weirs (Seungchon Juksan). While these aid in regional water security use reduce flooding, they flow summer, thereby frequently causing algal blooms. This study simulated bloom quality characteristics sections River South Korea under different weir operating conditions using Environmen...

Ciénaga de Mallorquín is a coastal lagoon designated as a RAMSAR site due to its ecological regional and international importance. In this work, the environmental fluid dynamics code explorer modeling system was implemented to determine the spatio-temporal distribution of temperature, dissolved oxygen, chemical oxygen demand and nutrient levels, and assess the trophic status of Ciénaga de Mallo...

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...

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...

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...
