“…In the literature, river networks have been studied from a physical, geometrical, and hydraulic point of view, introducing specific scaling laws that represent, within a given river basin, the relationships of scale invariance between topological variables (Dodds & Rothman, ; Gangodagamage et al, ; Hooshyar et al, ; Le & Kumar, ; Mantilla et al, ; Rodriguez‐Iturbe & Rinaldo, ) or between channel characteristics such as mean depth, water surface width, mean velocity, length of active wet channels, and discharge (among the most recent studies, Dodov & Foufoula‐Georgiou, ; Godsey & Kirchner, ; Hooshyar et al, ; Lawrence, ; Mersel et al, ; Nardi et al, ; Stewardson, ). In this research field, based on the contribution made by Mandelbrot (), several studies have applied fractal and multifractal analysis of river basins and networks in order to characterize many relevant geomorphologic and hydraulic‐hydrologic variables (Ariza‐Villaverde et al, , ; De Bartolo et al, , , ; De Bartolo, Primavera, et al, ; Dodds & Rothman, ; Dombradi et al, ; Ijjasz‐Vasquez et al, ; Perron et al, ; Rigon et al, ; Rinaldo et al, , ; Saa et al, ; Veneziano & Iacobellis, ; Veneziano & Niemann, ), while in very recent years, they have been extended also into the context of urban drainage basins (Gires et al, , ).…”
