Fig. 1: Global distribution of sea-level trends and time series analysis for major estuaries.
From: Global acceleration of compound flood risks through fluvial-tidal interactions in a warming climate
a Spatial distribution of sea-level rise trends (mm/year) across global coastal stations. The inset histogram displays the probability density of the trend distribution. The 20 major river-estuary systems (marked with their respective names and IDs 1–20) were selected based on the ranking of highest annual runoff volume and drainage basin area. The specific estuarine locations were defined by identifying the terminal grid point of the river flow and matching it to the nearest coastal grid point with valid sea-level data. b Historical time series of annual mean sea levels for the 20 selected major estuaries from 1950 to 2024. The red dashed line represents the linear trend. Note: The numbering corresponds to the basin IDs (1–20). The statistical significance of the trends is indicated in the top-left corner of each panel: an upward arrow followed by an asterisk (*) denotes a statistically significant increasing trend (\(p\)<0.05), whereas “ns” denotes a non-significant trend (\(p\)>0.05).
