rib and groove topography
- rib and groove topography
A local scale topography composed of repeating, small, high-angle (slopes generally 20 - 90 %), tertiary spur ridges or mini-interfluves (ribs) separated by small, natural, narrow drainageways (grooves); the overall effect is a corrugated transverse surface, common on the mid and lower slopes of well dissected uplands in semiarid to humid environments (e.g., Basin and Range, Ozarks, etc.). Micro-elevational differences generally range from < 3 to < 15 m.
