Flood planning for resilient infrastructure

Flood planning for resilient infrastructure

Australia has long been the land of flooding. Floods are the nation’s most significant natural disaster, and the risks can increase with changing rainfall patterns are growing. Climate change is altering rainfall patterns making future impacts potentially worse. Meanwhile urban growth continues to push development into flood-prone areas, increasing runoff, putting pressure on stormwater systems and adding complexity to infrastructure design.

Councils, road authorities, infrastructure developers and asset owners all face the same challenge: they often need robust flood risk information to inform decisions. We support this through modelling, practical engineering and advice to assist planning, design and approvals processes.

From flood studies for local councils to hydraulic design on complex infrastructure projects, our team of drainage and flooding professionals apply a broad range of skills across markets to help develop practical, drainage and flood solutions with constructability in mind.

What we do

Our flood engineering services

We help local councils, road authorities, developers and asset owners understand, plan, design for and manage flood risk. Our team combines technical expertise in hydrology and hydraulics with practical experience in flood related issues and remediation options.

Our approach

Our approach

On the ground and out in the rain

On the ground and out in the rain

Good flood modelling benefits from understanding how drainage infrastructure behaves. We consider how pits and culverts operate in real conditions, combining field knowledge with technical analysis to produce models that reflect relevant site conditions. This practical grounding can help identify issues that desk-based assessments may not reveal on their own.
Standards & Compliance

Our flooding methodology

We understand and apply relevant national and state standards to deliver flood studies and engineering designs.

Australian Rainfall and Runoff (ARR)

Australian Rainfall and Runoff (ARR)

ARR is a key national guideline for estimating design flood characteristics in Australia. We apply current ARR methodology across all flood studies and hydraulic assessments, and can assist clients understand how updates may affect existing studies and infrastructure planning.

State-based planning schemes

State-based planning schemes

Flood risk is embedded in planning approval processes, and we understand how flood overlay provisions may interact with development and infrastructure approvals. We provide technical inputs to support planning reports and development applications.
