Flood Emergency Response at the FMA Conference

Flood Emergency Response Community Meeting

Flood Emergency Response at the FMA Conference in Newcastle

The Floodplain Management Australia Annual Conference is being held next week (16-19th May 2017) in Newcastle, NSW. The conference theme, “Preparing for the Next Great Flood” will feature presenters from across the globe. This is an important floodplain management and flood emergency response event and Water Technology will be in attendance. A number of staff will attend with Ben Tate presenting a paper (Flood Emergency Response in Victoria) and Lachlan Inglis making a poster presentation (abstracts below).

Flood Emergency Response in Victoria – Ben Tate

During the 2010-11 floods the Victorian SES like many other agencies were stretched beyond imagination. The floods were difficult to respond to given the long duration. They brought much hardship to our flood prone communities. But it also began something innovative, and VICSES began to involve consultants in the flood emergency response. Water Technology assisted the VICSES through those floods and has been involved in all Victorian floods since.

Responding to a flood requires the cooperation of many agencies and community people. As a floodplain management consultant, we bring technical skills in hydrology, flood hydraulics, flood mapping, GIS, community consultation, and local knowledge on the floodplains where we have completed our studies. We have access to information and datasets that others may not. VICSES have found that involving consultants in the emergency response results in far superior outcomes. Not only do we have the technical skills to offer, but we also have a willingness to work in an emergency, with large teams to call on to help with resourcing through a prolonged flood.

Water Technology again assisted VICSES across three different Incident Control Centres in the recent floods in September 2016. This paper will discuss the role that consultants play in VICSES Incident Management Teams responding to floods. It is our understanding that consultants are not involved in flood emergency response in other States, and it is hoped that this paper may trigger discussions regarding how this Victorian approach may be worth considering and could benefit other States also.

If you would like to know more about how Water Technology provided support for flood emergency response attend the presentation or contact Ben to discuss.

Granite Creeks Regional Flood Mapping – The Good, the Bad and the Challenging – Lachlan Inglis and Ben Tate

 In the 6 years post the 2010-2011 Victorian floods, most of the larger flood prone regional towns have undertaken detailed flood mapping to provide a better understanding of the flood risk in these centres. To fill the gaps between townships the State has invested in regional scale flood mapping to improve flood mapping coverage across vast areas of rural floodplain.

This paper will provide a detailed analysis of the procedures undertaken for the Granite Creeks regional study, and ultimately highlight the benefits and challenges of undertaking flood mapping at a regional scale.

The Granite Creeks study is flood mapping 200,000 ha which encompasses three municipalities, with dozens of anabranching streams, and a contributing catchment area of over 400,000 ha. The mapping area extends from Avenel in the South to Baddaginnie in the north east and Shepparton in the North West. The catchment, much of which rises in the Strathbogie Ranges drains to the Goulburn and Broken Rivers and ultimately through the regional city of Shepparton. Detailed flood mapping currently exists for Shepparton as well as the townships of Euroa and Violet Town, however these three locations are only a fraction of the mapping area. Current mapping of the 1% AEP flood extent through much of the area lacks sufficient detail to undertake adequate decision making regarding planning, emergency management and insurance pricing.

The catchment lacks reliable streamflow and historical flood data, this was overcome using a range of hydrology and hydraulic calibration methods which also involved extensive community consultation. The hydraulic modelling approach incorporated the latest in flexible mesh floodplain modelling to provide detailed model results where required without compromising run time and data management.

The project included updating a streamflow gauge rating curve using the hydraulic model, online flood mapping, extensive community consultation, which resulted in an excellent product which was welcomed by agencies and the community.

If you are will be at the conference take some time to hear more about this project at the electronic poster display, or contact Lachlan to discuss. 


Ben Tate has been recognised as a finalist in the Floodplain Management Australia Excellence Award for The Allan Ezzy Flood Risk Manager of the Year with his flood emergency response assistance to VICSES and Victorian Catchment Management Authorities an important component of that recognition.
