Abstract
This repository contains the datasets required to reproduce the five figures presented in Astagneau et al. (2026). These data were generated according to the methods described in the paper. Users are encouraged to consult the Methods section to understand the data processing and derivation steps. Users are also encouraged to read the readMe file. Simulations for individual locations are subject to significant uncertainty. Therefore, interpretations of these simulations must be made carefully, especially for catchments smaller than 50 km², where uncertainties are particularly high.

## ReadMe file corresponding to "Daily and hourly projections of flood peaks, snowmelt and precipitation extremes for 384 catchments in Switzerland and Austria" ## 26.02.2026 ## Author: Paul C. Astagneau ## Please refer to the paper and to the description on the HYDROSHARE repository. ## ## Disclaimers ## Each file corresponds to the data needed to reproduce each Figure. ## The file names correspond to the figure number and the time resolution. If the variable is not indicated in the name, then it is streamflow. ## For Figure 5, the streamflow table used is the same as the table used for Figure 1. ## Please note that all variables are simulated variables from a hdyro-climatic modelling framework. Therefore they should not be considered as observations. ## If the name of the column is "Historical" or "Future", it means that the values are from the corresponding variable on the historical or the future period. ## The two files for Figure 2 are very heavy. Consider opening them from a programming language instead of Excel. ## ## Column/variable names: ## streamflow: specific streamflow [mm/timestep] ## snowmelt: snowmelt [mm/timestep] ## precipitation: total precipitation [mm/timestep] ## return_period: return period [year] ## Historical: values for the historical period (1991-2020) ## Future: values for the future period (2070-2099) ## middle_year: middle year of the 30-year period ## time: day of the selected flood peak [year-month-day] ## member: code referring to the climate member of the CRCM5-LE ## catch_code: code referring to one of the catchments (see catch_code.csv) ## resolution: time resolution of the underlying simulations (and reported variable -> important for the units) ## period: historical or future period ## subSample: bootstrap sample number
