4 sources for · 0 against

Geomorphological studies consistently show that river channel width scales predictably in relation to its contributing drainage area, typically expressed through power-law relationships.

Downstream hydraulic geometry relationships: Gathering reference reach-scale width values from LiDAR
2015 · cited by 25
The study relates downstream channel morphology, specifically bankfull widths, to drainage area and flow parameters.

The analysis

Multiple relevant geomorphology papers (e.g., [3], [4], [5], [8]) discuss and utilize the predictable scaling relationship between channel width and drainage area, supporting the claim without contradictory evidence.
