The study objective was to define flood behaviour in the catchments of Bungambrawatha Creek, Lavington, South Albury and West Albury for flood frequencies ranging between 5 and 500 year average recurrence interval, as well as for the Probable Maximum Flood. The flood study has three components:

• Review of available hydrologic and hydraulic data and previous investigations.
• A hydrologic component which included preparation of the hydrologic model of the study catchments.
• A hydraulic component which comprised the preparation and testing of hydraulic models of the main streams and floodplain areas.
