Overview

EART30182 (Hydrogeology) outlines the principles of physical and chemical hydrogeology; includes consideration of landfill site design with regard to aquifer protection; and the nature & dispersion of key contaminants in aquifers.

Aims

To introduce the principles of physical and chemical hydrogeology and the description of aquifers; to consider important aspects of groundwater contamination and aquifer protection.

Learning outcomes

Upon the successful completion of the module, students should be able to

* outline the major factors controlling the movement of groundwater,

* quantify such movement given appropriate well test or other data,

* outline the key characteristics of the major exploited aquifers within the UK

* demonstrate an understanding of the physical and chemical influences on the quality of groundwater resources and their vulnerability to contamination from human activities

* outline the variations of major elements in unpolluted waters as well as the sources and nature of key inorganic and organic pollutants,

* understand the principles of dispersion of pollutants in groundwater,

* appreciate the critical factors in the design of landfill waste disposal sites, particularly with regard to groundwater protection,

* quantify dispersion of pollutants given appropriate data

Syllabus

Physical Hydrogeology

[1] Introduction: definition, related disciplines, applications, aquifer properties.

[2] Fluid flow in aquifers: Darcy's Law.

[3] Fluid flow in aquifers: Flow Nets, Modelling Fluid Flow, Numerical Methods.

[4] Aquifer properties and their determination from pump tests.

[5] British aquifers: key characteristics of important aquifers.

Chemical Hydrogeology

[6] Groundwater chemistry: natural controls and variability.

[7] Groundwater pollution: nature of pollutants as chemicals; sources and behaviour.

[8] Chemical dispersion: patterns, processes and prediction.

[9] Disposal of waste by landfill: landfill site design and aquifer protection.

[10] Landfill leachates: chemical evolution and gas generation.

Assessment methods

ASSESSMENT

 

2 hour practical examination in May (40 % of marks).

1.5 hour written examination in May/June (60 % of marks).

 

All learning outcomes may be assessed by each assessment method but to varying degrees depending upon the assessment method, in particular:

(i) the practical examination will focus substantively more on assessing quantitative applications of theory;

(ii) the written examination will focus substantively more on assessing understanding of theory

 

FEEDBACK

 

Feedback on practicals and presentations will be made during practical classes.

Feedback on all formal assessment will be made via Blackboard and/or through a centrally arranged class feedback session.
