Experimental and Numerical Investigation of Evaluation of Grain Size–Based Porosity Models for Solute Transport through Porous Medium
Publisher: ASCE
Abstract: Uncertainties associated in tracer transport arising through various geological formations are often sorted by laboratory experiments on representative elementary volume (REV). To understand the effect of grain size and ...
Application of Triple Porosity Nonequilibrium Model to Simulate Fate of Solute through Heterogeneous Soil Column
Publisher: ASCE
Abstract: This study presents the application of a triple-porosity nonequilibrium model (TPNE) trifurcating the liquid phase within representative elementary volume (REV) in a saturated porous medium. The model accounts for both ...
Sustainable Landfill Liner Using Local Soils and Wastes Amended with Bentonite: Hydraulic Conductivity and Stochastic Leachate Transport Modeling
Publisher: ASCE
Abstract: Groundwater quality can be deteriorated by leachate that seeps through the landfills. Placing a low permeable barrier beneath the landfill is a cost-effective approach to protect the subsurface environment. Recently local ...
Corn Yield Simulation under Different Nitrogen Loading and Climate Change Scenarios
Publisher: American Society of Civil Engineers
Abstract: Climate change in recent years has been affecting agriculture and especially crop production worldwide. This study analyzes the effect of two different climate change scenarios on crop production of an experimental site ...
Reactive Transport in Fractured Permeable Porous Media
Publisher: American Society of Civil Engineers
Abstract: The transport of reactive solutes can be influenced by transport-related and sorption-related nonequilibrium processes. The reactive contaminant transport model for fracture and the multiprocess nonequilibrium (MPNE) model ...
Breakthrough Curves and Simulation of Virus Transport through Fractured Porous Media
Publisher: American Society of Civil Engineers
Abstract: In this paper, an advective dispersive virus transport equation, including first-order adsorption and an inactivation constant, is used for simulating the movement of viruses in fractured porous media. The implicit ...
Study of Dynamic Concentration Gradient on Mass Transfer Coefficient: New Approach to Mobile–Immobile Modeling
Publisher: ASCE
Abstract: The theory of mobile–immobile partitioning to capture a medium’s heterogeneity for simulating the interaction of contaminant mass between these two regions is still limited to the lump value of mass transfer coefficient ...
