AIMS

This subject covers theoretical and practical aspects of groundwater flow, and groundwater contaminant transport. The subject includes the field methods to characterise aquifers, the modelling of groundwater flow, and transport of, pollutants through porous media and reactions. The subject takes students fundamental knowledge of advanced differential calculus and flow processes and applies them to movement of pollutants in groundwater systems. Techniques learnt in this course may be applied in capstone design and research projects.

Concepts and techniques learnt in the subject are directly applicable to contemporary industry issues such contaminant movement through soils from poor historical industrial practice, the design and performance prediction of containment structures such as sanitary landfills or carbon dioxide geo-sequestration projects. The growth of manipulation of geological strata for coal seam gas extraction is another burgeoning area of industrial application of the learning of this subject.

INDICATIVE CONTENT

INTENDED LEARNING OUTCOMES (ILO)

On completion of this subject the student is expected to:

1. Design hydrogeological tests to obtain basic aquifer parameters
2. Compute groundwater flow and contaminant transport in porous media
3. Identify major sources and types of groundwater contamination
4. Recognize chemical reactions and biodegradation of groundwater contaminants
5. Quantitatively assess the fate of contaminants via modelling
6. Design basic site remediation.
