Anomalous transport on regular fracture networks: Impact of conductivity heterogeneity and mixing at fracture intersections.
We investigate transport on regular fracture networks that are characterized by heterogeneity in hydraulic conductivity. We discuss the impact of conductivity heterogeneity and mixing within fracture intersections on particle spreading. We show the emergence of non-Fickian transport due to the interplay between the network conductivity heterogeneity and the degree of mixing at nodes. Specifical...
متن کاملDiscretizing the fracture-matrix interface to simulate solute transport.
This article examines the required spatial discretization perpendicular to the fracture-matrix interface (FMI) for numerical simulation of solute transport in discretely fractured porous media. The discrete-fracture, finite-element model HydroGeoSphere (Therrien et al. 2005) and a discrete-fracture implementation of MT3DMS (Zheng 1990) were used to model solute transport in a single fracture, a...
متن کاملEstimation of zeolite application effect on solute transport parameters at different soils using HYDRUS-1D model
ABSTRACT-Application of models for simulation of solute and pollutants transport in soil can reduce time and costs for remediation process. HYDRUS-1D model was developed to simulate the one–dimensional flow of soil water, heat, solute and viruses in variably saturated–unsaturated porous media. The objective of this investigation is to determine the solute transport parameters in disturbed soil ...
متن کاملSolute transport in a coupled fracture- matrix system with sinusoidal fracture geometry
ABSTRACT Modeling of fluid flow and solute transport through fractured rock is an important component of engineering analysis in many disciplines including groundwater contamination, nuclear waste disposal, petroleum and gas production, mine excavation and geothermal production. Several studies have been conducted on single rock fracture using parallel plate model. An attempt has been made to s...
متن کاملExtraction of model parameters for reactive solute transport
In the present study, tried to examine the reactive solute relationships for transport and degradation processes through the rockfill media. By applying the analytical solution of reactive transport, the 1st to 3rd theoretical temporal moments have been extracted then, by using two methods of curve fitting and temporal moment matching, the coefficients of dispersion and degradation have been ex...
