Fig. 6

Spatial distribution of randomly generated multiscale patches for 15 cases, randomly generated under the same fractal size–number distribution. Each model includes three different ranks of patches (\(k = 2,3,\;{\text{and}}\;4\)), denoted by light blue, dark blue, and purple, respectively. The background region is yellow, with \(w_{c} = 0. 8 {\text{m}}\) and \(w_{0} = 2. 4 {\text{m}}\), and is assumed to represent a larger patch of rank \(k = 1\)
