An international flood warning specialist is examining the effectiveness of emergency warnings during Wimmera floods as part of a Horsham and Wartook Valley Flood Investigation.

Neil Dufty from Sydney-based natural hazard, ecological and environmental company Molino Stewart will speak at community meetings this month in Laharum, Wonwondah and Horsham.

Mr Dufty is the Regional Director of The International Emergency Management Society (TIEMS) for Australia, New Zealand and Oceania and a member of the International Advisory Board of the Centre for Floods, Communities and Resilience at the University of Western England.

He has more than 35 years’ experience in environmental education and management and has worked specifically in developing disaster plans for schools, communities, government agencies and businesses.

The first meeting is at Laharum Community Hall on Tuesday November 28. Another meeting is at the Wonwondah Community Hall on Wednesday November 29, then at Horsham Golf Club on Thursday November 30. All meetings are from 7.30 to 9pm.

Meeting organisers are seeking community feedback on new flood maps and potential mitigation options for the MacKenzie River, Burnt and Bungalally Creeks and other waterways south of Horsham.

The flood extent maps for the Horsham and Wartook Valley Flood Investigation are a result of 12 months of analysis of community flood knowledge including learnings from the January 2011 and September 2016 floods.

The investigation is also more accurately mapping the impact of stormwater in Horsham during January 2011 and September 2016.

Wimmera CMA chief executive David Brennan said it was exciting to reach this stage. He said they were keen for the community to review the maps and compare them with their own observations. 

“We are seeking community input on mitigation options to reduce flood impacts for the 121,500-hectare study area.

“Following the first round of meetings last year we received lots of valuable information in terms of flooding extents, depth and timing. This is a good chance for the community to ask questions and comment upon the new mapping.”

Mr Brennan reiterated that local flood information and validation was invaluable to flood investigations.

“The more information we receive the more confidence we have in the final products the flood investigation produces,” he said.

The investigation will inform flood response agencies and enable better protection and improved preparedness for future flood events. 

Results will also form part of Local Government planning schemes, giving the community and councils a better indication of likely flood impacts on future building developments. 

“All this information will help emergency services, Local Government and other agencies prioritise future work helping to improve emergency planning for future flood events,” Mr Brennan said.
