North Esk and Tamar River Flood Water Surface Profiles

Aggregating flood water surface profiles for the North Esk and Tamar rivers in Tasmania, Australia, derived from hydrological studies. It includes profiles for 100-year and 200-year Average Recurrence Interval (ARI) flood events, with adjustments for sea level rise. The underlying hydrology was reviewed by Hydro Consulting for the South Esk and derived by the University of New South Wales Water Research Laboratory for the North Esk.

Use Cases

• Model 100-year and 200-year Average Recurrence Interval (ARI) flood profiles for infrastructure planning.
• Analyze the impact of an 800mm sea level rise on 100-year ARI flood levels in the Tamar estuary.
• Calibrate hydraulic models using peak discharge data from historical floods, such as the 470 cumecs event in August 2005.

Strengths

• Includes specific flood profiles for 100-year and 200-year Average Recurrence Interval (ARI) events.
• Hydrological analysis was conducted by specialized entities: Hydro Consulting and the University of New South Wales Water Research Laboratory.
• Model calibration references two historical flood events with recorded peak discharges (470 cumecs in 2005, 251 cumecs in 2011).

Limitations

• The dataset's core structure (e.g., row count, column names) is not explicitly defined in the provided metadata.
• Spatial coverage is limited to specific river reaches from the Black Bridge to Corra Linn on the North Esk and the Tamar estuary.
• Temporal coverage of the underlying hydrological studies (2006, 2008) may not reflect recent climate or land-use changes.
