Flood Analysis and Emergency Response
Producing network damage analysis and reporting in the midst of a flood emergency.
In March 2021, an Australian utility’s network was heavily inundated by unprecedented flash flooding. The utility faced significant outages and asset damage across its network.
The utility was already utilizing Neara’s Design tools to accelerate their design process. When the flood emergency occurred, they approached the Neara team for an urgent and immediate solution to be able to understand the effect of the floods on their network.
Neara delivers a true digital twin for the infrastructure industry, enabling complex engineering-grade analysis automatically and at a whole-of-network scale. This fully customizable design, analytics and reporting platform is cloud-based, providing ease of access and collaboration.
We implemented a variety of flood-mapping tools for the utility. These included:
A “floodwater simulator” with user-defined water depth that could be run across the network
Output reports for flood-water height per pole and span-submersion events
Polygon layers for expected flood areas from open-source government data
Network-wide reports on flood activity were visible and editable in Neara Analytics within 48 hours of the emergency commencing – as flood waters were still rising.
The utility actively used the flood-mapping features to assist in power restoration to customers. The reports produced helped the utility to prioritize pole inspections and to understand possible hazards before going to the site.
