Modeling working group:
Learning Finite Differences with a Darcy Apparatus
Summary
Our working group was charged with coming up with ways of introducing FD techniques. This is a visual (lab) methodology for teaching finite differences using a Darcy column. After students have learned Darcy's law, the apparatus can be used to introduce the concept of finite differences by dividing the column into sections.
Context
Audience
This is for an introductory level (junior, senior) hydrogeology course
Skills and concepts that students must have mastered
Students will learn the concepts of numerical methods and finite differences for simulating hydraulic heads
How the activity is situated in the course
Haven't used this yet. This was developed during the workshop this summer in our working group.
