RISStudy on the Self-Sustaining Inlet Boundary Conditions for Numerical Simulation on Local Scour
Publisher: ASCE
Abstract: In previous numerical simulations of local scour, the steady flow is normally adopted as the inlet boundary condition, and the approach flow is always assumed as a homogeneous isotropic turbulence. In the present study, ...
Hierarchical Bayesian Estimation of Safety Performance Functions for Two-Lane Highways Using Markov Chain Monte Carlo Modeling
Publisher: American Society of Civil Engineers
Abstract: A critical part of any risk assessment is identifying how to represent exposure to the risk involved. Recent research shows that the relationship between crash count and traffic volume is nonlinear; consequently, a simple ...
Photolysis, Biodegradation, and Sorption Behavior of Three Selected Phenolic Compounds on the Surface and Sediment of Rivers
Publisher: American Society of Civil Engineers
Abstract: In this study, laboratory experiments were carried out to investigate the environmental behavior of three selected phenolic compounds [2, 4-Dichlorophenol (DCP), 2, 4-Dinitrophenol (DNP) and 2, 4-Dimethylphenol (DMP)] in ...
Combined Impacts of Land Use and Climate Change in the Modeling of Future Groundwater Vulnerability
Publisher: American Society of Civil Engineers
Abstract: Groundwater vulnerability assessment delineating areas that are susceptible to contamination from future scenarios has aroused worldwide attention. In this study, the authors (1) estimate future groundwater vulnerability ...
Collecting Particulate Matter and Particle-Bound Polycyclic Aromatic Hydrocarbons Using a Cylindrical Thermal Precipitator
Publisher: American Society of Civil Engineers
Abstract: Thermophoresis has been used to develop various thermal precipitators; however, their collection performance for ambient particulate matter (PM) with an aerodynamic diameter less than 10 μm (PM10) has been rarely ...
