Swan Hill Drainage Strategy

This project addressed persistent challenges for the Swan Hill and Robinvale townships caused by inadequate drainage infrastructure and flat terrain, which have resulted in extended water retention after local storm events. The study focused on assessing the current stormwater infrastructure and developing computational models to identify optimal strategies for future drainage management.

The scope of the project involved establishing a 2D hydraulic model to better understand flood risk under existing conditions, the first of its kind for both townships. The models were used to assess current drainage performance during various storm events and identify capacity shortfalls. The models were then used to investigate potential mitigation options, informed by the priorities of local residents and council officers. Community consultations were conducted to ensure local insights were considered in the development of effective drainage solutions.

The study delivered a detailed report documenting the model establishment, and outlining proposed drainage improvements, including infrastructure upgrades tailored to meet the specific needs of each township. The findings support the council in prioritising flood mitigation projects, reducing flood risks, and ensuring the long-term sustainability and safety of the Swan Hill and Robinvale communities.
