CEG8522 : Groundwater Chemistry (Inactive)

Semesters
Semester 2 Credit Value: 10
ECTS Credits: 5.0

Aims

This module will provide an understanding of:
•       the fundamental principles and factors that control and influence groundwater chemistry, rock-water reaction rates, and the application to various operational contexts;
•       how to develop and apply appropriate sampling and analytical approaches to collection and interpretation of hydro-chemical data;
•       the prediction of changes using a range of appropriate modelling approaches.

Teaching Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

Teaching Rationale And Relationship

Specialist knowledge and understanding are primarily imparted via lecture classes, supported by computer-hosted reference materials. Subject specific skills are taught through tutorials, and a computer-based workshop.

Students are encouraged and expected to learn through independent reading. They are supported in this by the provision of an extensive, but prioritised, reading list. Observations and discussions during the modelling workshop aid development of understanding.

Subject specific skills are learnt through practice on worked examples based on real life case studies, and participation in, and reflection on, the computer-based workshop using geochemical calculations.

Key skills are practised through participation in the computer-based workshop and in completion of the assessed coursework.

Assessment Rationale And Relationship

The specialist knowledge and understanding imparted during this module are assessed by means of unseen
written examination and a single coursework item.

The examination paper employs a range of approaches in order to accurately assess student abilities. These include multi-part questions aimed at testing basic knowledge, calculation methods, data interpretation, and practical application.

The coursework is designed to develop understanding and skills taught during the module through assessment and interpretation of hydrochemical data sets from a case study application.
