Why it matters
This experiment helps researchers understand how substances disperse in river systems.
Key points
- In September 2017, USGS released 72.57 kg of Rhodamine WT dye into the Kootenai River.
- The dye was released from the Kootenai Tribal Fish Hatchery in just 90 seconds.
- An aircraft mapped the dye plume using hyperspectral imaging from 1,000 meters above.
- Five water quality sondes tracked the dye concentration in the river.
- Measurements continued for nearly 40 hours after the dye was released.
Key insights
- The experiment could improve methods for tracking pollutants in rivers.
- Remote sensing may provide valuable data for environmental monitoring.
- Findings could support hydrodynamic models used in river studies.
