We use multifractal analysis to estimate the Renyi
dimensions of river basins by two different partition methods.
These methods differ in the way that the Euclidian plane
support of the measure is covered, partitioning it by using
mutually exclusive boxes or by gliding a box over the plane.
Images of two different drainage basins, for the Ebro and
Tajo rivers, located in Spain, were digitalized with a resolution
of 0.5 km, giving image sizes of 617×1059 pixels and
515×1059, respectively. Box sizes were chosen as powers
of 2, ranging from 2×4 pixels to 512×1024 pixels located
within the image, with the purpose of covering the entire network.
The resulting measures were plotted versus the logarithmic
value of the box area instead of the box size length.
Multifractal Analysis (MFA) using a box counting algorithm
was carried out according to the method of moments
ranging from −5 | |
