“In September 2017, the US Geological Survey (#USGS) carried out an unusual experiment on Idaho’s Kootenai River. Researchers released 72.57 kg (160 pounds) of Rhodamine WT dye into the river and then followed its movement through the water. The aim was to understand how a substance spreads as it travels through a flowing river.
According to USGS, the dye was released from a single point at the Kootenai Tribal Fish Hatchery on September 26, 2017. The entire release took just 90 seconds. Researchers then had to track what happened to the dye as it moved downstream and spread across the river.
They used two methods to follow the plume. Instruments placed in the river measured the dye directly, while an aircraft flew over the Kootenai River the following day, capturing images of the plume from above. Together, the two sets of observations helped researchers study how the dye changed as it moved through the river.
The aircraft carried a hyperspectral imaging system, which can record information from different parts of the electromagnetic spectrum rather than taking an ordinary photograph. It flew about 1,000 metres above the ground while making several passes along the river. The images showed the changing plume across the river channel…
The experiment was not simply about photographing a coloured patch moving through the Kootenai River. The researchers were testing whether remote sensing could help measure the concentration of a tracer dye as it spread…”
