We develop three-dimensional computational fluid dynamics (CFD) models to investigate the hydraulic behavior of complex structures, scour risk, thermal plume mixing and sediment flow and deposition. These simulations allow a rapid assessment of hydraulics at initial stages of an engineering project, allowing early design optimization and testing. Our team uses CFD programs such as OpenFOAM and Flow3D, often in conjunction with our Tuflow, Delft3D or HEC-RAS hydrodynamic models.

We undertake very-large catchment hydrology and national scale flood mapping. Our Australia Flood Maps have been continuously updated since 2014, and now include pluvial and fluvial hazards for six return periods (20, 50, 100, 200, 500 and 1,500-year), at a 5m (city) and 30m (regional) resolution. The flood maps have been subject to regular updates in 2015, 2016, 2019 and 2021. The latest updates include BoM 2016 IFDs, hydrology following ARR, and high-quality LiDAR elevation throughout cities and major regional areas.
