Table 1 . Hydrological characteristics of selected categories (mean±S.D., N=10). Inundation frequency (IF) was calculated as the mean proportion of days where the pixel was inundated either for the central pixel or in the peripheral pixels (excluding the central pixel). Dry proportion is the proportion in the peripheral pixels with IF<0.45, and the heterogeneity index is calculated with the Shannon Diversity Index for the peripheral pixels.
