Fig. 3: Along-valley patterns in cross-valley locational probability.
From: Big data show idiosyncratic patterns and rates of geomorphic river mobility
Individual bars represent regular 0.01 km intervals in the downstream direction. White spaces indicate zones of no data (for example, where the active channel was too narrow to be resolved, see Methods section). Grayscale shading beneath barcode plots represents the valley floor width smoothed over 1 km of river segments using a moving mean. This was mapped from a nationwide IfSAR-derived DEM acquired in 2013 with a 5 m spatial resolution. Trunk channels are sorted by the mean cross-valley locational probability (most stable, top, to least stable, bottom). Visually, some of the prominent hotspots of geomorphic river mobility appear to coincide with topographic settings where the valley floor widens (for example, Laoag, Abulug and Chico). The satellite-derived observations indicate the spatially heterogeneous nature of geomorphic river mobility.
