CENV6154 Groundwater Hydrology and Contamination

Module Overview

This module will describe how to assess the groundwater water resources of the UK and other countries, how to determine the key aspects of local and regional hydrogeology, and how to create ground water models. Engineering applications will include assessing and dealing with groundwater contamination and dewatering for construction sites.

Aims and Objectives

Module Aims

The module considers the characterisation of key aquifer types (permeability, transmissivity, storage) using both laboratory and field methods. Aquifer pumping tests will be described and the numerical techniques that are used to calculate aquifer properties. Students will learn how to construct functioning groundwater models using MODFLOW and then apply the models to solve engineering problems. Applications in water resources, foundation de-watering and contaminated groundwater will be described using a series of case studies.

Syllabus

The module will be in four sections. A provisional schedule of lecture topics is also given, but this may change due to the availability of guest lecturers from Industry. A) Hydrogeology and Aquifer properties. Aquifer types and characteristics will be described. Groundwater hydrology will be discussed in detail and related to the water resources of the local region (Southern England). The hydraulics of pumped wells will be explained together with analytical methods used in the analysis of well pumping tests. B) Groundwater modelling. The governing equations of groundwater flow will be described, together with analytical and numerical approaches to the solutions of the equations. Students will be introduced to model construction using Visual MODFLOW and a series of self study exercises in groundwater and contaminant movement will be undertaken. C) Groundwater contamination. Guidelines for assessment for contaminated land used in the UK based on current legislation will be explained. Monte Carlo methods of uncertainty analysis will be used to identify what risks are associated with using groundwater affected by contamination. D) Engineering application. Regional water resources, Foundation dewatering, contaminated groundwater. Week 1 Course introduction - overview. Introduction to Hydrogeology. Aquifer Characteristics. Week 2 Fundamentals of water storage and groundwater flow. Darcy, Dupuit, Laplace equations. Week 3 Flownet analysis and flownet construction. Week 4 Water wells. Radial flow. Pumping tests. Capture zones. Delayed yield. Boundaries. Week 5 Case study : Hampshire. Field visit. Water Resources - recharge estimation, saline intrusion near the coast. Week 6 Introduction to MODFLOW - steady state aquifer, transient contamination examples Week 7 MODFLOW examples and exercises. Week 8 Contaminated groundwater - overview and legislation. Fate and transportation mechanisms Week 9 Contamination - risk analysis. Exercises –Ogata & Banks equation, Monte Carlo approach. Week 10 Groundwater in construction. Dewatering practical considerations Week 11 Dewatering 2 - case studies, Exercises. Christmas break Week 12 Exercises. Revision class.

Special Features

A half day field visit to the Chalk aquifer and river system of Hampshire will be included. Students will visit groundwater monitoring boreholes, river flow structures and devices and water supply pumping stations.

Learning and Teaching

Teaching and learning methods

The module will consist of lectures, self-study exercises and coursework. Lectures will cover background theory and introduce groundwater resource assessment methods, model construction and validation and will also describe a series of case studies. There will be informal exercises, and if time permits, a field visit. A coursework task will be set to develop understanding of modelling a groundwater problem.
