Probabilistic Analysis of Pollutant Migration from a Landfill Using Stochastic Finite Element Method
Publisher: American Society of Civil Engineers
Abstract: Here a probabilistic study is attempted to analyze the pollutant migration in the soil liner while assuming the parameters of the soil liner viz hydraulic conductivity, dispersion coefficient, porosity, and sorption ...
Spatial Moment Analysis for Transport of Nonreactive Solutes in Fracture-Matrix System
Publisher: American Society of Civil Engineers
Abstract: This paper presents an analysis using spatial moments for transport of nonreactive solutes in a single fracture-matrix system using a dual porosity framework. The velocity and dispersion obtained using the first and second ...
Numerical Modeling and Analysis of Solute Velocity and Macrodispersion for Linearly and Nonlinearly Sorbing Solutes in a Single Fracture with Matrix Diffusion
Publisher: American Society of Civil Engineers
Abstract: The behavior of the solute velocity and effective macrodispersivity of solute front in the fracture for the transport in a single fracture in the presence of rock matrix diffusion is analyzed using numerical modeling. The ...
Time-Dependent Dispersivity of Linearly Sorbing Solutes in a Single Fracture with Matrix Diffusion
Publisher: American Society of Civil Engineers
Abstract: Field studies show that the variance of travel distance often increases nonlinearly with time elapsed after release of solute tracers. The nonlinear relationship between variance of travel distance and time is attributed ...
Coupled Solution for Forced Recharge in Confined Aquifers
Publisher: American Society of Civil Engineers
Abstract: Analytical solutions for forced well recharge currently in use were initially developed for pumping scenarios and applied for recharge cases assuming that radial flow in the recharge well replicates a mirror image of that ...
Numerical Simulation of Groundwater Flow with Gradually Increasing Heterogeneity due to Clogging
Publisher: American Society of Civil Engineers
Abstract: Well injection replenishes depleting water levels in a well field. Observation well water levels some distance away from the injection well are the indicators of the success of a well injection program. Simulation of the ...
Temporal Moments for Reactive Transport through Fractured Impermeable/Permeable Formations
Publisher: American Society of Civil Engineers
Abstract: The transport of reactive solutes through fractured porous formations has been analyzed. The transport through the porous block is represented by a general multiprocess nonequilibrium equation (MPNE), which, for the fracture, ...
