Figure 9.10 a) Final calibration curve between red band brightness and water depth after application of the correction procedure.
The three distinct bands seen in Figure 9.9 have merged into 1 after the correction procedure, b) Final validation relationship testing
the predictions of the calibration equation versus additional, independent, field data. From Carbonneau, P. E., Lane, S. N., and

fluvial environments. Earth Surface Processes and Landforms, 31(11), 1413-1423. Reproduced from Carbonneau et al. (2006), with
