Summary

This activity has three exercises:
  1. measuring groundwater flow and velocity,
  2. measuring vertical gradients in piezometers, and
  3. sampling a well field.
These field exercises are meant to give students better comprehension of groundwater-stream interactions. It is better for use in smaller classes, as some instrumentation is needed.

Context

Audience

For upper level undergraduates and lower level graduate courses on hydrogeology or hydrology.

Skills and concepts that students must have mastered

Students must have reviewed Darcy's Law, concepts of hydraulic gradients, and some basic aquifer test methodology.

How the activity is situated in the course

Exercise should be coupled with lecture discussion of groundwater-surface water interactions.
