The objectives of this part of the Warracknabeal and Brim Flood Investigation are to:

1. conduct an assessment of the existing total flood warning system (TFWS) for the investigation area

2. recommend improvements to the existing TFWS based on the assessment.

In Australia, the concept of the TFWS has been used to describe the full range of elements that must be developed if flood warning services are to be provided effectively. Guidance relating to the development and assessment of theTFWS has been provided by the Australian and Victorian governments.

Molino Stewart was commissioned by Water Technology to conduct this part of the investigation. It consulted with communities in the study area along Yarriambiack Creek. It consulted other stakeholders including the Bureau of Meteorology (BoM), Victoria State Emergency Service (VICSES), Wimmera Catchment Management Authority and Yarriambiack Shire Council. It also used data from the 2015 flood investigation conducted by Water Technology and demographic data sources such as the Australian Bureau of Statistics. The report makes several recommendations to develop a TFWS based on the findings of the investigation.
