Flood forecasting Parramatta

Parramatta is described as Australia’s tiger economy. Located 23 kilometers west of Sydney’s central business district, it is rapidly driving growth and long-term prosperity for both businesses and residents. But when the clouds burst, City of Parramatta is prone to flash floods from the parramatta river.

To create a connected, resilient community and minimise the impact of flooding, City of Parramatta uses a state-of-the-art flood warning system. It is powered by Royal HaskoningDHV’s Flash® service, developed in partnership with Nelen & Schuurmans Consultancy, which has long standing experience in flood forecasting and information systems.

Royal Haskoning DHV implemented their flash flood warning service Flash to help The City of Parramatta to create better resilience and protection for residents and businesses from the negative impact of floods.

The Parramatta services is built using Lizard technology and uses the 3Di hydrodynamic calculation engine as backend.

Data engineers built a connection with the Bureau of Meteorology to import their advanced and detailed precipitation forecast. Together with water level monitoring data imported from the City of Parramatta, the precipitation is fed to a ultrafast 3Di flood hydrological model. This model, created by hydrological modelling experts, simulates a forecast of the water levels in the Parramatta River. The simulations are fed back to Lizard where they are post-processed to create maps that provide the system water depths, flood hazards and arrival times. Based on these maps alarms are triggered when a flood is expected. Once alarms are triggered, the flood simulations are automatically stored for evaluation and for the system to learn from the event.
