Extended Data Fig. 8: Bank erosion assessment.
a, Example cross-sections on the right bank near km 151 with estimated erosion line (red triangles). b, Cross-section at km 151.14 (yellow line in panel a) and eroded area based on cross-sectional profiles and impoundment level. c, Example erosion lines before (blue) and after (red) the flood. d, Matching erosion volumes per section of 10 m long (distance in flow direction). e, Erosion volume per 5 km river length at the left and right banks. Dotted black lines show the locations of 7 barrages in the river. f, Average bank displacement per 5 km river length at the left and right banks.
