WMS was engaged by Latrobe City Council (LCC) to conduct a comprehensive flood mitigation study for the township of Glengarry. This project aimed to review and enhance previous hydraulic models, particularly focusing on the waterways Eaglehawk Creek and Four Mile Creek in alignment with the updated Australian Rainfall and Runoff Guidelines (ARR19). The study involved hydraulic modelling using TUFLOW software for flood behaviour assessment during a 1% Annual Exceedance Probability event.

The project assessed four mitigation options collaboratively developed with LCC and the West Gippsland Catchment Management Authority (WGCMA). Results indicated that the Traralgon Maffra Road Levee Mitigation Option was the most effective, significantly reducing flood risk with minimal adverse off-site impacts.

WMS recommended further steps, including a comprehensive cost-benefit analysis of the detailed mitigation options. These proactive measures guided Council in prioritising flood risk reduction strategies, ensuring community resilience and long-term sustainability for the Glengarry township.
