Topographic Anisotropy Figure 5

Figure 5: A) Sine wave surface used as a simplified replication of synform-antiform pairs found in Central Otago. B) Anisotropy measured at two points in Manuherikia River Valley (red) and the secondary gorge (yellow). Numbers represent the wavelength in kilometers for the indicated ellipses. Anisotropy measured up to maximum wavelength of 25 km in the valley, 7.5 km in the gorge. C) Anisotropy magnitude and D) orientation map at 1 km, E) F) 5 km, and G) H) 10 km wavelength.
