Results
Our data compare very well to the 25 validation reaches, with a mean
absolute error of 2.84 meters per year and a bias of 0.39 meters per
year (Figure 2a). Unfortunately these limited validation sites are not
equally distributed around the world and do not represent a very broad
range of morphologies (Figure S5). Nevertheless, our validation results
suggest that our method and implementation in GEE can capture riverbank
erosion with similar accuracy to studies focused on smaller domains.
