Short Summary

This study empirically compares cascading drought-flood events (CDFEs) with flood-only events (FEs) in Central Europe, revealing that CDFEs are associated with significantly higher streamflow, deeper water depths, and greater economic losses.

Objective

• To identify and characterize cascading drought-flood events (CDFEs) and flood-only events (FEs) across Central Europe.
• To link these event types to their flood impacts, specifically comparing physical characteristics (streamflow, water depth) and economic losses between CDFEs and FEs.

Study Configuration

• Spatial Scale: Central Europe
• Temporal Scale: Historical period (specific range not specified in abstract)

Methodology and Data

• Models used: Identification of CDFEs and FEs; linking to flood impacts. Specific models for event identification/impact assessment not detailed in abstract.
• Data sources: Modelled Historical Analysis of Natural Hazards in Europe database

Main Results

• Cascading drought-flood events (CDFEs) are associated with significantly higher maximum daily mean streamflow (58.51 m³ s⁻¹) compared to flood-only events (FEs) (38.20 m³ s⁻¹).
• CDFEs exhibit deeper mean water depths (1.90 m) compared to FEs (1.88 m).
• CDFEs result in greater economic losses (€33.09 million km⁻²) compared to FEs (€29.75 million km⁻²).

Contributions

• Provides empirical evidence on the distinct physical characteristics and economic impacts of cascading drought-flood events (CDFEs) compared to flood-only events (FEs).
• Addresses a critical gap in understanding how drought-flood interactions translate to economic losses.
• Underscores the necessity of considering the special features of CDFEs in flood risk management strategies.
