The word "navigable" has been employed in literature to describe not only the physical condition of waterways but also their practical and economic potential. In many of the accounts by Lewis and Clark ([1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11]), the term is used with precise detail to indicate whether a river or stream could accommodate canoes, boats, rafts, or even steamers, emphasizing aspects like width, depth, current, and obstacles such as rapids. In other historical texts and documents—including those by Livy ([12]), Strabo ([13], [14]), and various political treatises ([15], [16], [17], [18])—"navigable" similarly underscores the economic and strategic significance of waterways, suggesting that their usability could influence trade, transport, and even military logistics. Additionally, its usage by authors like E.M. Forster ([19]) hints at metaphorical and playful connotations, extending the idea of navigation to structured or harmonious progress. Thus, across a range of contexts, "navigable" serves as a key descriptor, linking natural conditions to broader human endeavors.
