North Esk and Tamar River Flood Water Surface Profiles

Featuring 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) events, with discharges modeled for specific historical floods. The data is intended for planning purposes.

Use Cases

• Model flood water surface profiles for the North Esk River from Black Bridge to Corra Linn using the provided ARI profiles.
• Analyze the impact of an 800mm sea level rise on 100-year ARI flood levels in the Tamar River region.
• Calibrate hydrological models using discharge data from the 2005 (470 cumecs) and 2011 (251 cumecs) flood events mentioned in the description.
• Compare flood discharge estimates for the North Esk and South Esk rivers across different Average Recurrence Intervals (e.g., 10, 20, 50, 100, 500 years).

Strengths

• Includes modeled flood profiles for specific 100-year and 200-year Average Recurrence Interval (ARI) events.
• Hydrology derived from studies by the University of New South Wales Water Research Laboratory (2006) and Hydro Consulting (2008).
• Models were calibrated against two recorded historical flood events with peak discharges of 470 and 251 cumecs.

Limitations

• The specific data format and structure (e.g., row/column count) are not detailed in the provided input.
• Geographic coverage is limited to the North Esk and Tamar river systems in Tasmania, Australia.
• The dataset's primary stated purpose is planning, which may limit its granularity for other analytical uses.
