North Esk and Tamar River Flood Water Surface Profiles

A collection of 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 scenarios like a 100-year ARI with an 800mm 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 flood inundation extents using the 100-year and 200-year ARI flood water surface profiles for land-use planning.
• Analyze the impact of sea level rise on flood levels by comparing the standard 100-year ARI profile with the profile incorporating an 800mm rise.
• Calibrate hydraulic models using the documented peak discharges from historical flood events, such as the 470 cumecs event in August 2005.

Strengths

• Includes flood profiles for specific, high-impact recurrence intervals (100-year and 200-year ARI).
• Models incorporate a specific sea level rise scenario of 800mm for climate change impact assessment.
• Hydrological analysis is based on studies from authoritative institutions like the University of New South Wales Water Research Laboratory and Hydro Consulting.

Limitations

• The dataset's temporal coverage and update frequency for the underlying hydrological models are not explicitly stated.
• Spatial coverage is limited to specific river reaches from the Black Bridge to Corra Linn on the North Esk and into the Tamar.
