Otago extreme sea levels analysis

The ORC commissioned the National Institute of Water and Atmospheric Research Ltd (NIWA) to determine extreme sea levels with return periods of 2, 5, 10, 20, 50 and 100 years for eight locations along the Otago coastline.

The eight locations are:

  • Oamaru
  • Kakanui River Mouth
  • Shag Point
  • Otago Heads (Spit Jetty)
  • Otago Harbour (Port of Dunedin)
  • Taieri River mouth
  • Clutha River mouth
  • Catlins River mouth

The focus is on extreme sea levels to be used as ocean boundary conditions for river flood modelling.
