Data for: Channel mobility and floodplain reworking across river planform morphologies

Source-to-sink transfer of sediment and organic carbon (OC) is regulated by river mobility. Quantifying trends in river mobility is, however, challenging due to diverse planform morphologies (e.g., meandering, braided) and measurement methods. Here, we utilize a state-of-the-art remote-sensing method applicable to all planform morphologies to quantify the mobility timescales of 80 rivers worldwide. Results show that, across the continuum from meandering to braided rivers, there is a systematic reduction in timescale of channel mobility and—to a lesser extent—the timescale of floodplain reworking. This leads to an overall decrease in the efficiency at which braided river channels rework old floodplain material compared to their meandering counterparts. Reduced reworking efficiency of braided channels stems from their relatively smaller channel-belt areas relative to their channel area. Results suggest that river-mobility timescales can help us characterize sediment and OC storage and tra..., This dataset was collected using a novel framework to quantify river mobility from remotely sensed data. We use Google Earth Engine hosted Landsat 5, 7, and 8 multi-spectral images to generate channel mask time series for 80 rivers across the globe., , This README file was generated on 2024-04-15

# General information:

## Dataset title

Data for \"Planform Morphology Control on River Mobility and Floodplain Reworking\"

## Overview

This supplementary dataset includes all underlying data included in the associated manuscript. The bulk of the included files are the binary channel masks to derive mobility measurements. We include all the necessary files to generate your own raster data, and reproduce the analyses used in the article. We also include all the tabular mobility calutations for the 80 rivers.

## Data Formats

* **Tabular Files:**:
* **.csv**: Broadly used to record mobility calculations at the individual river level as well as aggregated data across all rivers. Naming conventions are descriptive, and include the river name and what the data the file contains.
* **Text Files:**
* **.txt**: Used to describe directory-sepcific metadata--primarily column descriptions for tabular .csv files.
* **Raster Files:**...
