Global net increase in surface water connectivity in river–floodplain systems

This repository contains the relevant code and data for the paper Global net increase in surface water connectivity in river–floodplain systems (https://doi.org/10.1038/s41561-026-01953-y). Specifically, the code_SurfaceWaterConnectivity.rar file includes the associated codes for calculating the surface water connectivity based on the binary images. The SurfaceWaterConnectivity_InRiverFloodplainSystem.rar file is a shapefile containing 28,723 polylines of river centerlines. The Y40M50.rar file contains surface water connectivity data at the pixel level for the period 1984-2019 under normal inundation conditions. Please reser to the readme.docx file for more detailed infomation.
