RISComparing Two Methods for Addressing Uncertainty in Risk Assessments
Publisher: American Society of Civil Engineers
Abstract: The Monte Carlo method is a popular method for incorporating uncertainty relative to parameter values in risk assessment modeling. But risk assessment models are often used as screening tools in situations where information ...
Hybrid Approach for Addressing Uncertainty in Risk Assessments
Publisher: American Society of Civil Engineers
Abstract: Parameter uncertainty is a major aspect of the model-based estimation of the risk of human exposure to pollutants. The Monte Carlo method, which applies probability theory to address model parameter uncertainty, relies on ...
Geosynthetic Clay Liner Interaction with Leachate: Correlation between Permeability, Microstructure, and Surface Chemistry
Publisher: American Society of Civil Engineers
Abstract: When a geosynthetic clay liner (GCL) containing sodium bentonite is brought into contact with fluids containing other cations, the latter may exchange with the sodium present between clay layers. This modification of clay ...
