Using satellite images to understand changes in river flow

Researchers used satellite images to derive a global dataset of river width data, expanding the understanding of at-a-station hydraulic geometry. The study found that a 1% increase in discharge leads to a median 0.2% increase in river width worldwide, with weaker responses in areas with cohesive soil and high forest coverage.
