Microrelief surface forms and shapes define the degree of vehicle mobility and terrain trafficability with their deviations (Weiss, 1981;Mintzer and Messmore, 1984;Terrain Analysis, 1990;Shoop, 1993;Murphy and Randolph, 1994;Baylot et al, 2005;Pahernik et al, 2006;Durst et al, 2010;Rybansky et al, 2015). Microrelief forms and phenomena that affect surface roughness include canals, embankments, gullies, ravines, surface rocks, surface stones, and landslides.…”
