Virginia TechAuthor Profile
Used this activity? Share your experiences and modifications
This activity has three exercises:
- measuring groundwater flow and velocity,
- measuring vertical gradients in piezometers, and
- sampling a well field.
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.

Description of the activity/assignment
In class, instructor provides background on groundwater-surface water interactions, defines the hyporheic zone, and describes why knowledge of the HZ is important for both hydrology and ecology.
