Resumen:
The fractal dimension (D) was estimated for nine tidal channels depicted in thematic mapper (TM) Landsat-5 imagery toderive information about the degree of geomorphological control on a tidal channel network characteristic of the Bahı´a BlancaEstuary (Argentina). Two methods, box counting and contiguity, were used to estimate fractal dimensions for each tidalchannel. All channels produced D values close to 1, meaning that they are self-affine fractal features. However, these fractaldimensions do not represent the meandering pattern complexity characteristic of the tidal channels analysed. Although bothmethods allowed for estimation of D, the contiguity method showed that three of the channels actually are not fractal but havesinusoidal characteristics, a condition that was not detected by the former method.
