The groundwater system allows for injection and extraction of subsurface flow from the stream table, making possible a wide array of experiments and demonstrations. A small pump supplies a spray bar at the upstream end of the table to produce groundwater flow. Extraction filters are installed at the downstream end of the table. The extraction filters connect to tubes that empty into the reservoir. The extraction tubes have valves allowing the user to increase, decrease, or turn off groundwater extraction.
Watch the video below to see setup of the groundwater system controller and multiple experiment ideas.
With the Groundwater System, you can:
- Create groundwater-fed springs, headwaters, and lakes
- Study tributary dynamics and multi-channel systems
- Study headwater stream migration
- Observe flooding lake overflow
