Implementation of four conceptual rainfall-runoff models to simulate drought-to-flood transitions in Chile and Switzerland

Here, we present the calibrated parameters for the different 60 KGE configurations (5 KGE formulations x 3 streamflow transformations x 4 weights), 4 hydrological models (GR4J, GR5J, GR6J, and TUW), and 63 catchments (24 in Chile and 39 in Switzerland; see "_Study_domain_filter_v2025_v4.png") used to prepare the manuscript “How well do hydrological models simulate streamflow extremes and drought-to-flood transitions” submitted for consideration for publication in Hydrology and Earth System Sciences (HESS). Additionally, performance metrics and figures for the observed and simulated transitions are included.

Each ZIP file contains several CSV data files and PNG images (see "Folders_structure.png"). The name of the folders is given by the database (i.e., CAMELS-CL or CAMELS-CH), followed by the code associated with the station (id_gauge). Thus, the file "camelscl_5722002.zip" corresponds to the catchment with code 5722002 associated with the CAMELS-CL database.

Additionally, two zip folders are included, containing:

• Basic_Scripts.zip: Basic R-functions used to configure the hydrological models, identify streamflow extreme events and their transitions, and analyze the ability of models to capture such events.
• summary.zip: Compilation of the results retrieved from the analysis of the simulations across catchments (i.e. merge the '02_Analysis_DDS' folders).
