A river plume is not a line on a map. It is a moving body of water with different temperature, color, chemistry, and density.
Seeing the pulse
Satellite imagery can track suspended sediment and chlorophyll, while models estimate how wind and currents move the plume after storms.
Why timing matters
Communities downstream care about where the plume carries nutrients, pollutants, and heat. A forecast can help target sampling boats and protect sensitive sites.
The field check
Water samples still anchor the remote signal. Without them, color can be mistaken for chemistry and a sharp boundary can hide vertical structure.
