This dataset presents the results presented in Couasnon et al. (2019) - Measuring compound flood potential from river discharge and storm surge extremes at the global scale. For more information about the methods, please refer to the paper. This dataset was created using as input time series of discharge and maximum storm surge at river mouths globally from 1980 - 2014.
