Postgraduate Course: Environmental Site Assessment Project: A Field and Modelling Investigation (PGGE11281)
|School||School of Geosciences
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 11 (Postgraduate)
||Availability||Available to all students
|Summary||In this course students conduct a hydrogeological environmental site assessment of a real field site with a hands-on project involving each phase of a typical site assessment (i.e., desktop, field, modelling investigations) with a specific focus on learning to integrate field- and modelling investigations to develop a holistic understanding of hydrogeological systems. The first part of the course students learn the environmental site assessment process and will conduct a desktop investigation of the project site. The second involves a mix of learning field measurement techniques and field-site visits to characterise the project site. Finally, students implement their collected field data into an industry-standard commercial groundwater modelling package, learn to use geostatistical methods to fill gaps in their field data and account for field-measurement uncertainties. At the end of this course students will present their environmental site assessments in a professional written report.
Provide an academic description, and outline of the content covered by the course and a description of the learning experience students can expect to get.
While hydrogeology topics are often taught in isolation from one another, environmental site assessments and investigations require hydrogeologists to synthesize information from a broad range of topics and sources, including both field and modelling data. This is not straightforward as numerical models require precise information on the distribution of parameters across a site (e.g., permeability) yet field-investigations rely on techniques such as boreholes and pump-tests to produce point-source estimates of these parameters with large gaps between measurement points. As a result, synthesizing both field and modelling data to develop a holistic understanding of a groundwater system requires an understanding of their respective limitations and sources of uncertainties as well as the use of geostatistical techniques to interpolate between measurement points.
In this course, students will conduct an environmental site assessment for a real field site. For this project, students will: 1) conduct a desktop investigation of the site, 2) go to the project field site and characterising the site with hands-on field methods, and 3) implement the collected data into an industry-standard software package to model groundwater behaviour at the site. In the first half of the course, specific focus is placed on learning field measurement techniques and gaining hands-on experience with them at the project field site to characterise the groundwater system. The second half teaches students: a) an industry-standard commercial modelling software package, b) how to implement their collected field data into the model, c) the use of geostatistical techniques to extrapolate the collected field data across the entire site, and then d) model the field site. Students will then deliver a professional written environmental site assessment report including each phase of their investigation. During this process, students will learn how to critically evaluate field and numerical investigation techniques, and how to identify their limitations and sources of uncertainty.
The course lectures develop students┐ ability to synthesize knowledge and techniques learned from other courses into a single, comprehensive site investigation. Lectures are supported by hands-on practicals. The first part of the course, practicals have students visiting the field site and conducting their own field investigations. The second part of the course, practicals are focused on numerical modelling and report writing.
The course will consist of 3 hour lectures each week, as well as hands-on laboratory and field practicals.
