Projected High-Tide Flooding Frequency for Jiangsu and Shanghai Coasts, China

The coasts of Jiangsu and Shanghai, China, are the focus of this dataset. It contains projections of future high-tide flooding frequency for six tide gauge stations, derived from a multi-factor statistical prediction framework. The data was authored by Shiwei Wen and last updated on June 1, 2026.

Use Cases

• Modeling future coastal flood risk based on sea-level rise projections under different emission scenarios.
• Assessing the regional modulation of flood risk based on tidal-amplitude amplification and non-tidal residuals.
• Comparing flood hotspot sensitivity across different coastal geomorphologies, such as Haizhou Bay and the Yangtze Estuary.
• Informing regionally differentiated coastal adaptation and resilience planning based on quantified factor contributions.

Strengths

• Projections are based on a multi-factor statistical framework that decomposes water levels into sea-level rise, tidal-amplitude, and non-tidal residual components.
• Quantifies specific contributions, such as tidal amplification alone contributing up to 124 additional flood days per year at Lianyungang by 2100.
• Covers six specific tide gauge stations along the Jiangsu and Shanghai coasts, providing localized risk assessment.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• The dataset is very small at 29.6 KB, indicating limited scope or summary-level data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
