Water flowing downhill following the path of steepest descent is a foundational physical principle based on gravity and basic topography, requiring no citation.

The analysis

The claim states a fundamental physical truism regarding gravity and fluid flow on slopes (water follows the path of steepest descent as a first-order approximation), which is common knowledge in earth sciences and everyday observation. Papers on landscape evolution and hydrology assume this baseline without needing it as a contested hypothesis.
