Flow and Transport Modelling
Flow and transport models allow us to predict the behaviour of groundwater systems and the movement of contamination through these systems. This knowledge can be applied in evaluating remediation alternatives and defining areas of concern for wellhead protection. Other uses include source identification and impact assessment.
Intera has a strong heritage in developing, testing and applying numeric models for groundwater flow and transport. We have applied a variety of models ranging from commonly used models such as MODFLOW and MODPATH to more specialized codes such as FRAC3DVS, SWIFT, TOUGH2 and UTCHEM. In addition, Intera has developed and modified existing codes for specific projects. For example, one-dimensional unsaturated and unsaturated flow and transport codes were modified for use in a coupled unsaturated-saturated stochastic model.
Our staff are proficient in applying models in complex settings, taking into consideration both the capabilities and the limitations of numeric models. We have used computer models to simulate:
- Assessment of remediation alternatives at historic waste management facilities.
- Migration of radioactive waste from geologic disposal sites in fractured media
- Capture zone delineation and identification of wellhead protection zones for municipal supply wells
- Infiltration of contaminants from underground storage tanks, agricultural activity and road salting
- Leachate plume development and migration at landfills
- Dewatering of pits, quarries, mines and underground facilities
- Migration of contaminants from mine tailings disposal facilities and performance of in-pit tailings management facilities
- Analysis of hydraulic tests performed under non-ideal test conditions
- Multivariate mixing and mass balance of hydrogeochemical data
As flow and transport models are typically complex and associated with large data sets, effective visualization of results is essential. Intera uses mView, a software application developed in-house for the support of numeric modeling, to generate report-quality graphics. Animations of results can also be produced to enhance the presentation of results.
