Fractal characterization of a hydrological basin using SAR satellite images

We propose a methodology to analyze self-similar organization of hydrologic al basins from satellite imagery and, more specifically, adapted to high-re solution radar images. We show that, when it is applied to several Amazonia n rivers and lakes, it provides results in excellent agreement with the fra ctal theory. This allows us to suggest some novel relations between the riv er stream length, the river bed area, and the catchment basin area.
