Hydro-CH2018-Runoff Ensemble: Daily Simulated Runoff for 93 Swiss Catchments (1981-2099)

93 Swiss catchments have daily runoff simulations from 1981 to 2099 under three RCP scenarios. The dataset was generated by researchers at the University of Bern using the PREVAH hydrological model and published in 2021. It includes daily, monthly, seasonal, and yearly aggregated data from multiple GCM-RCM chains for each scenario.

Use Cases

• Projecting long-term changes in river discharge based on multi-model climate ensembles.
• Analyzing seasonal runoff patterns (winter, spring, summer, autumn) under different emission scenarios.
• Comparing hydrological responses across 93 different Swiss catchments.
• Validating and calibrating other hydrological models using the provided simulated runoff data.

Strengths

• Covers a long future projection period from 1981 to 2099.
• Includes data for 93 distinct catchments across Switzerland.
• Provides an ensemble of simulations from 12, 25, and 30 GCM-RCM chains for RCP2.6, RCP4.5, and RCP8.5 scenarios respectively.
• Data is structured at daily, monthly, seasonal, and yearly temporal aggregations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
