Norfolk Tide Sensor Readings From Five Waterways

Data.norfolk.gov provides tide level readings from five sensor stations in Norfolk, Virginia waterways. The dataset tracks daily water levels from September 30, 2020 to the present. The City of Norfolk publishes this data with a disclaimer regarding its unverified status and accuracy.

Use Cases

• Model water level correlations between stations like 'Lafayette River at Mayflower Rd' and 'Elizabeth River Main Branch at Nauticus'.
• Analyze tidal patterns and anomalies using the 'LocalTime' and 'Timestamp' columns across all five gauge locations.
• Compare typical tide readings from standard gauges against data from the altered flow at 'Mason Creek at Granby St'.
• Forecast local flooding by monitoring real-time levels at key points like 'Little Creek at 20th Bay St'.

Strengths

• Data spans from September 30, 2020 to present, providing a multi-year time series.
• Includes concurrent readings from five distinct geographic locations within Norfolk.
• Updated daily, offering recent observations for analysis.

Limitations

• Data from the Mason Creek station flows through a weir system, making its readings not directly comparable to others.
• The City explicitly disclaims expert review, verification, and guaranteed accuracy of the gauge calibrations and recordings.
• Unknown sample size and row count limits statistical analysis scope.
