Abstract
Ettema and Kempema document many unique geomorphological processes operating in ice-affected rivers, but state that major geometric parameters such as channel width, hydraulic radius, and thalweg sinuosity are not likely altered significantly by ice. While no thorough study has investigated this problem, I pose for discussion the idea that ice-affected rivers do imprint signatures on many so-called universal properties of river basins. I argue that the timing and magnitude of geomorphologically effective flows are altered by ice, and that this shouldaeffect the equilibrium form of rivers. I use hydraulic geometry in an arctic river as an example.
