Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Geomorphological and fluid dynamic studies demonstrate that meandering river formation is driven by fluid flow instabilities and continuous sediment erosion and deposition processes along channel banks.

The analysis

The claim addresses the established geomorphological mechanisms of meandering rivers, which are well-supported by numerous hydrodynamic and sediment transport models in the literature (e.g., papers 0, 1, 3, and 9). The papers detail bend stability, flow resonance, and erosion-deposition dynamics. There are no papers refuting this fundamental geomorphological principle.
