Temora Flood Study

The Temora Flood Study was commissioned by Temora Shire Council and the NSW state government to define the existing flood behaviour in the township of Temora; including the open channels through the town and Trigalong Creek that is located to the west of the town. The open channels through town (known as the eastern and western drainage lines) are concrete-lined and drain an urban area of 24 square kilometres to Lake Centenary. Trigalong Creek is a vegetated channel that drains an area of 153 square kilometres to Lake Centenary.

The outcomes of this study include:

  • Establishment of a WBNM hydrologic model and a TUFLOW hydraulic model;

  • Calibration of the models to the March 2012 and September 2016 flood events;

  • Modelling of design flood events as per ARR 2016 for the 0.2 EY, 10% AEP, 5% AEP, 2% AEP, 1% AEP, 0.5% AEP, 0.2% AEP and the PMF event; and

  • Mapping of peak flood depths, velocities, flood function, flood hazard, emergency response classification of communities, and interim flood planning areas.
