“…The main purpose of this study is to use the finite element code MOTIF (Model Qf Transport !n Fractured/porous media) to predict the groundwater flow and tracer distribution oattern in a tracer test in the Twin Lake aquifer. The code has already been verified (Chan et. a/., 1987), tested on groundwater flow field experiments (Davison and Guvanasen,1985), and tracer tested in a fracture zone (Scheier et.…”

The economic importance of groundwater has increased in recent times. The problem of groundwater contamination and the consequent health threat has been of major concern to groundwater engineers and scientists. This has given rise to an increase in the use of numerical models in predicting contaminant concentrations and travel times in aquifers. In this paper, the numerical model code MoIF (Model Qf Transport !n Fractured/porous media) is used to predict the groundwater flow pattern and conservative tracer transport in the Twin Lake aquifer, Ontario. The MorlF code is a three-dimensional finite element code designed to model the coupled processes of groundwater flow, contaminant and heat transport in porous media. The groundwater flow pattern in the Twin Lake aquifer is simulated in both twoand three-dimensions and the results are compared to field data. The influence of dimensionality on the flow simulation is evaluated by comparing the results of two-and three-dimensional flow simulations. The two sets of flow simulation results were in good agreement with the field data. The results of the three-dimensional flow simulation compared better with the field measuremenrs than those of the two-dimensional simulation. The velocities calculated from the three-dimensional flow model were projected onto a two-dimensional section through the model and used to predict the spatial and temporal distribution pattern of the tracer concentration in a tracer test in the aquifer. The predicted tracer plume compared well with the observed plume in the initial stages but began to show some deviations with time.

“…Picard's iterative scheme is used to solve the coupled flow and transpott equations in which fluid density and dynamic viscosity can be dependent on temperature, pressure and solute concentration. Furlher details can be found in Chan et al, (1987). In the present application constant fluid properties were assumed.…”

“…Yet, Grisak and Pickens (1981) have already been presented an analytical solution for comparatively simple cases, such as tracer flow through a single fracture. Chan et al (1987) compared analytical solutions for a single fracture with the numerical 3-D-code MOTIF (model of transport in fractured/porous media) while Reimus and Haga (1999) provided analytical solutions for a dual porosity conceptual model.

“…In the geosphere model, the transport of contaminants through segments of the rock is treated using one-dimensional diffusion-advection equations. The segments and equations are based on the groundwater flow paths and velocities calculated by three-dimensional modeling using the MOTIF computer program [6]. In the biosphere model, transport of contaminants in the soil is modeled as a statistical representation of the predictions of SCEMR, a computer program used to model the transport mechanisms in detail [7].…”

Abstract. In order to establish the safety of a disposl system for high-level radioactive waste, the system must be shown to satisfy radiological safety criteria imposed by regulatory agencies. In Canada, for example, the regulatory policy includes a quantitative limit on radiological risk to an individual for a period of 10,000 years following disposal. Mathematical modeling of the performance of the disposal system is essential to demonstrate that the system meets such quantitative criteria. There is considerable uncertainty in modeling the system because of the limited knowledge of both the geological environment of the disposal facility and the behavior of the engineered and natural components of the system far into the future. Procedures to reduce the uncertainty must be carried out during the entire life of the disposal project, and the uncertainty must be quantified to the extent possible. It is important that the limitations of the models be recognized, as well as their effectiveness in providing essential information in the siting, design, and regulatory process. A case study based on the concept proposed for the disposal of nuclear fuel waste in Canada demonstrates the use of mathematical modeling of a disposal system.
