Yangtze Estuary Tidal Height Data During 1954 and 2020 Flood Periods

Hourly tidal height data from eight gauges in the Yangtze Estuary, China, collected during two major flood periods. The dataset covers 15 July to 15 August 1954 and 1 July to 31 July 2020, with heights referenced to the Wusong datum. Leicheng Guo published this data on figshare in 2026 to support a related paper in AGU Advances.

Use Cases

• Modeling flood risk in tidal rivers based on hourly tidal height data from eight gauges.
• Comparing historical flood events based on data from the 1954 and 2020 flood periods.
• Analyzing tidal response to river discharge based on data referenced to a common datum (Wusong).
• Validating hydrodynamic models for the Yangtze Estuary based on gauge-specific time-series data.

Strengths

• Data spans two significant flood events separated by 66 years (1954 and 2020).
• Includes hourly measurements from eight distinct gauge stations (Datong, Wuhu, Maanshan, Nanjing, Zhenjiang, Jiangyin, Xuliujing, Wusong).
• Data is referenced to a consistent vertical datum (Wusong mean low water).
• Sourced from official hydrological books and regional water resource management departments.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Temporal coverage is limited to specific one-month periods for each year.
