North Esk and Tamar River Flood Water Surface Profiles

Featuring flood water surface profiles for the North Esk and Tamar rivers in Tasmania, Australia, intended for planning purposes. It includes profiles for 100-year and 200-year Average Recurrence Interval (ARI) events, with discharges derived from studies by the University of New South Wales Water Research Laboratory and Hydro Consulting. The data was calibrated against historical floods from 2005 and 2011.

Use Cases

• Model flood inundation extents using the provided 100-year and 200-year ARI water surface profiles for urban planning.
• Analyze the impact of an 800mm sea level rise on flood levels by comparing the two provided 100-year ARI profiles.
• Calibrate hydrological models using the discharge values for different ARI events, such as the 10-year and 50-year discharges listed in Table 1.
• Assess flood risk for infrastructure by referencing the adopted tail-water level of 2.1 m AHD at the river junction.

Strengths

• Includes specific flood profiles for 100-year and 200-year Average Recurrence Interval events.
• Hydrological data is derived from studies by authoritative institutions: University of New South Wales Water Research Laboratory and Hydro Consulting.
• Model calibration is based on two recorded historical flood events from 2005 and 2011.

Limitations

• The dataset's spatial coverage is limited to the North Esk River from Black Bridge to Corra Linn and the Tamar River confluence.
• No row or column count is provided, making the dataset's exact size and structure unknown.
• The primary focus is on planning, which may limit its granularity for detailed hydraulic engineering analysis.
