Supplementary data for "Accelerated river mobility linked to water discharge variability"

Supplementary data for the paper "Accelerated river mobility linked to water discharge variability", by Leenman et al.

This repository contains 3 datasets underlying the figures in the manuscript and supporting material.

ds01_flow_gauge_metadata: Details and locations of flow records used in our analysis.

ds02_Qvar_and_TR: Floodplain reworking timescales, channel characteristics, sediment concentrations, and discharge variability metrics (i.e. all metrics used in our figures and modeling). Floodplain reworking timescale data are from Greenberg et al., 2024. Channel slopes, widths, planforms and catchment areas are from Galeazzi et al., 2021. Bed-material sediment concentration estimates are generated from WBMsed (Cohen et al., 2022). 

ds03_channel_threads_GRWL: Data used to make one of our supplemental figures. Frequency count of the number of reaches that have a given number of channel threads in the Global River Widths from Landsat (GRWL) database (Allen and Pavelsky, 2018). Data downloaded via Google Earth Engine. Only reaches wider than 1000 m are included.
