Fig. 11From: Morphometric measurements of bedrock rivers at different spatial scales and applications to geomorphological heritage researchSurface scans of a 5 × 5 mm area on crest slopes. The stoss slopes (a) show elongated scratches corresponding to the main northeast-southwest flow direction, which superimposes to the secondary flow forming the crests and troughs. Pits of various sizes on lee slopes (b) are formed by the action of the secondary flow forming crests and troughsBack to article page
