Short Summary

This study developed a hydrological model based on the SCS-CN methodology and GIS to estimate flood hydrographs in the upper Biała Lądecka River basin, Poland, and analyzed a dam failure, aiming to corroborate climate change impacts on floods and aid future flood forecasting and adaptation.

Objective

• To develop a hydrological model using the SCS-CN curve methodology and GIS to estimate the flood hydrograph in the upper parts of the Biała Lądecka River basin in Poland.
• To analyze the possible causes of the Stronie Śląskie reservoir dam failure in the year 2024 using hydraulic routing calculations.
• To corroborate the influence of climate change on flood events and their consequences.
• To assist in forecasting future catastrophic hydrological events for earlier adaptation and infrastructure reinforcement against future flooding.

Study Configuration

• Spatial Scale: Upper Biała Lądecka River basin, Poland, with specific focus on the town of Lądek-Zdrój and the Stronie Śląskie reservoir.
• Temporal Scale: Event-based analysis of flood hydrographs and a specific dam failure event (2024), with implications for future flood forecasting and long-term adaptation.

Methodology and Data

• Models used: SCS-CN (Soil Conservation Service Curve Number) hydrological model, GIS (Geographic Information Systems), Hydraulic routing calculations.
• Data sources: Data from the Polish Institute of Meteorology and Water Management (IMGW) for model calibration.

Main Results

• The developed SCS-CN and GIS-based hydrological model successfully estimates the flood hydrograph in the upper Biała Lądecka River basin, demonstrating its effect at Lądek-Zdrój.
• Hydraulic routing calculations provided an analysis of the possible causes of the Stronie Śląskie reservoir dam failure in 2024.
• The study supports the influence of climate change on flood events and their consequences.

Contributions

• Development of a relatively simple and widely applicable SCS-CN and GIS-based hydrological model for flood forecasting in ungauged or data-scarce watersheds.
• Provision of a methodology for analyzing specific dam failure events and their potential causes.
• Corroboration of the link between climate change and flood events, offering a tool for forecasting future catastrophic hydrological events.
• Assistance in informing strategies for earlier adaptation and reinforcement of infrastructure against future flooding.
