Catchments do not strictly follow Budyko curves over multiple decades but deviations are minor and predictable

The supplementary data is provided in the form of an Excel file which consists of two sheets. ST-1 consists of data for individual catchments, and ST-2 consists of data for regional marginal distributions of deviations

ST-1: The topographic characteristics for all study catchments (Latitude, Longitude, Area, Elevation), the length of the runoff data availability, mean precipitation for the period 1901-2015, mean 20-year evaporative indices for the five 20-year periods, median deviation values along with the skew normal distribution parameters and p-values of the Wilcoxon Signed Rank Test for each 20-year distribution deviation are provided. p-values of the Kolmogorov-Smirnov Test, performed on the two consecutive distribution of deviations, are provided in the next columns. Similarly, the long-term median deviation values, IQR of the deviations, fitted distribution parameters and temporal stability flag of aggregated marginal distribution of deviations along with associated changes in Q are provided. The last column shows the IQR of median deviation values for the 20 individual moving window aggregated marginal distribution of deviations.

ST-2: Long-term median deviation values, IQR of deviations, and parameters of the fitted regional distributions of deviations along with the number of catchments in each category are provided.
