North Esk and Tamar River Flood Profiles for Planning

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) events, with discharges calibrated to historical floods from 2005 and 2011. The data is intended for general planning purposes.

Use Cases

• Model flood inundation extents using the 100-year ARI profile with current sea level conditions for urban planning.
• Assess climate change impacts by comparing the 100-year ARI profile with an 800mm sea level rise scenario.
• Analyze flood discharge relationships between the North Esk and South Esk rivers using the provided discharge tables.
• Calibrate hydrological models using the successfully calibrated North Esk model data from the 2005 and 2011 flood events.

Strengths

• Profiles are based on specific hydrological studies from the University of New South Wales Water Research Laboratory (2006) and Hydro Consulting (2008).
• Model calibration is validated against two recorded historical flood events (2005 and 2011).
• Includes multiple planning scenarios such as 100-year ARI, 200-year ARI, and a sea level rise condition.

Limitations

• The spatial coverage is limited to the North Esk River from Black Bridge to Corra Linn and the Tamar River confluence.
• The dataset's primary stated purpose is for general planning, which may limit its suitability for detailed engineering design without additional validation.
• The underlying raw data tables and full model parameters may not be fully accessible within the provided file formats.
