Brief Description
The course provides an introduction to quantitative (analytical and numerical) analysis of groundwater flow, solute transport, and unsaturated flow.
Four Fundamental Aspects
Groundwater is treated as:
- Natural System - Part of hydrologic cycle; distribution, movement, interaction with geologic framework
- Resource - Exploration, development, production; mapping and simulation tools
- Environmental System - Aquifers as dispersive propagation systems for chemical/pollution stresses
- Managed System - Integrated approach to use, conservation, remediation, quality control
Special emphasis on cross-over between hydrogeology and rock mechanics / engineering geology.

Common Student Questions (FAQ)
| Question | Response |
|---|---|
| "Do I need to know Python?" | Basic familiarity helps, but you won't write code from scratch. Focus on understanding what the code does. |
| "What's on the exam?" | Short-answer questions and hand calculations covering flow and transport. Exercises are representative. One A4 notes page allowed. |
| "Does the quiz count?" | No, the formative quiz is ungraded. It's for your benefit to check understanding before the exam. |
| "How is the project graded?" | Report (25%) + presentation (25%). Rubric published at project start. Focus on understanding over complexity. |
| "Can I use AI tools?" | For learning, yes. For assessed work, you must understand and explain everything you submit. |
| "How much time should the project take?" | Target ~40-50 hours over the project phase. If it's taking much longer, ask for help. |
