Development of Geophysical Tools for Mapping Geoenvironmental Remediation

Successful remediation of DNAPL-contaminated sites requires adequate characterization of the volume and extent of the DNAPL source zone. Geo-electrical techniques, such as electrical resistivity tomography, can be sensitive to subsurface electrical changes caused by the presence and/or movement of contaminants. Despite the potential of these methods and the success of controlled field and laboratory experiments, field application of ERT, IP and GPR to locate or map contaminant source zones is not extensively practiced.

The focus of Mehrnoosh's Master's program is the exploration of this topic within a theoretical and computer modeling framework. The unique coupling and development of hydrogeological and geophysical numerical models have provided a methodology for valuable and realistic exploratory simulations and a framework for developing and testing new ERT, IP and GPR quantitative interpretation tools. The project includes the development of novel coupled numerical models, fundamental advances in knowledge in an emerging, cross-disciplinary area, and real applicability to current field practice with future commercial potential.

Personal Background

Mehrnoosh obtained her BSc (Aug 2008) and MSc (May 2011) in Mining Engineering from Tehran University which is one of the most prestigious and well known universities in Iran. During her master thesis, she applied a novel method of modeling; wavelet neural network (WNN) to oil reservoir characteristics. WNN offers new aspects of modeling by selecting an appropriate function according to data characteristics.

Mining activities disturb existing geo-water systems balance and cause serious long period environmental impact. Because of acidic mine drainage and heavy metals, groundwater contamination is a common environmental problem in mining area. Based on her prior knowledge and strong passionate about environmental issues, she was eager to deepen her knowledge in the area of Contaminant Hydrogeology. She made a decision to join the RESTORE research group at The Western University. Mehrnoosh joined the RESTORE group as a Master of Engineering Science student in January 2012.
