The Moulamein Flood Study was prepared for Murray River Council and the NSW state government. The study area focused on the township of Moulamein, which is located on the confluence of the Edward River and Billabong Creek. The town is surrounded by three levee systems: the northern levee system around the village centre, the southern levee system around primary production land and the water treatment plant, and the western levee system around Moulamein Bowling Club.

The outcomes of this study include:

• A Flood Frequency Analysis (FFA);

• Establishment of a TUFLOW hydraulic model;

• Calibration of the model to the October 2016 and validation of the model to the July 1956 flood events;

• Modelling of design flood events as per ARR 2019 for the 20% AEP, 10% AEP, 5% AEP, 2% AEP, 1% AEP, 0.5% AEP, and the PMF event; and

• Mapping of peak flood depths, velocities, flood function, flood hazard, and interim flood planning areas.
