Fig. 6: Continuum of geomorphic river mobility behaviours for characteristic segments with single-thread and multi-thread channel patterns.
From: Big data show idiosyncratic patterns and rates of geomorphic river mobility
Upper panels show the spatial distribution of per-pixel locational probability across 20 km river segments; lower panels show the corresponding CFD curves. Bold numbers denote the segment averaged per-pixel locational probability (μ). Thick blue lines represent CFD curves for the full segment; thin grey lines represent non-overlapping 5 km reaches. The symbol (
) denotes coordinate locations close to the selected river segments: (a) Cagayan (17°09’52.6”N 121°49’43.9”E); (b) Cagayan (17°24’02.2”N 121°44’19.8”E); (c) Cagayan (17°49’04.0”N 121°39’31.1”E); (d) Abra (17°33’46.7”N 120°41’30.2”E); and, (e) Chico (17°32’09.1”N 121°25’50.7”E). For river segments with similar segment averaged per-pixel locational probabilities (for example, c and e), the shape of the CFD curves and intercept positions (λ) are comparable. We note that inter-reach variability is considerable within segments (for example, c), indicating a range of mobility behaviours over relatively short lengths. The base maps are (a–e) extracts of the hillshaded digital elevation model (see Methods section).
