Comparisons of channels in intertidal mudflats and simulated planforms. (A) Low-sinuosity channels in an intertidal river bank and (B) a simulated low-sinuosity channel (R = 0.005; S = 0.01; R/S = 0.5). (C) High-sinuosity channels in an intertidal mudflat and (D) a simulated high-sinuosity channel (R = 0.005; S = 0.001; R/S = 5). (E) Intertidal channels that cross a break in slope (dotted line) from gentle (A–A′) to steep (B–B′), and (F) a simulated channel over a slope break based on (E) (25), where S ∼ 0.005 between A and A′ and S ∼ 0.04 between B and B′, using a resistance of R ∼ 0.05 derived from Fig. 2.
