DESCRIPTION - summary of the module content

Groundwater is important as a resource but also as an environmental contamination pathway; it also has an impact on engineering and mining projects. The Hydrogeology module covers all these aspects and provides a detailed practical introduction to groundwater and how it can be investigated and modelled. There are no pre-requisite modules but a mathematical background from CSM 1027 or equivalent is necessary.

AIMS - intentions of the module

A comprehensive introduction to hydrogeology introducing basic concepts and principles, derivation and application of mathematical models and applications of hydrogeological investigations, interpretation, assessment and problem solving.

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

On successful completion of this module you should be able to demonstrate:

Module Specific Skills and Knowledge:

1.An understanding of the basic principles and concepts applied in hydrogeology.

2.Application of hydrogeological assessment techniques.

3.Use of analytical and numerical models for hydrogeological quantification and problem solving.

4.An ability to design, plan, conduct and interpret hydrogeological investigations.

5.An awareness of the implications of actions on the water environment and foresee, avoid and remedy engineering problems associated with adverse groundwater conditions.

Discipline Specific Skills and Knowledge:

6.Analyse engineering and environmental problems and situations.

7.Conduct calculations correctly, neatly and be able to comment whether their answers make senseÓ”.

Personal and Key Transferable/ Employment Skills and  Knowledge:

8.Learning, problem solving, data-handling, applied mathematics and reporting.
