Ice velocity distribution at the Minjibu Bend. Subfigures (a), (b), and (c) respectively show the spatial distribution of ice velocity, scatter plots of ice velocity in the pixel coordinate system, and the variation of ice velocity along vertical cross-sections of the bend-apex upstream. Subfigures (d), (e), and (f) respectively show the spatial distribution of ice velocity, scatter plots of ice velocity in the pixel coordinate system, and the variation of ice velocity along vertical cross-sections of the bend-apex. Subfigures (g), (h), and (i) respectively show the spatial distribution of ice velocity, scatter plots of ice velocity in the pixel coordinate system, and the variation of ice velocity along vertical cross-sections of the bend-apex downstream. The original images in panels (a), (d), (g) are captured by the DJI Mavic 3Â T drone during the ice run period.
