DHI Water and Environment Pty Ltd

DHI are the first people you should call when you have a tough challenge to solve in a water environment – be it a river, a reservoir, an ocean, a coastline, within a city or a factory. Our knowledge of water environments is second-to-none.

It represents over 50 years of dedicated research and real-life experience from more than 140 countries. We strive to make this knowledge globally accessible to clients and partners by channelling it through our local teams and unique software.

Our world is water. So whether you need to save water, share it fairly, improve its quality, quantify its impact or manage its flow, we can help. Our knowledge, combined with our team’s expertise and the power of our technology, holds the key to unlocking the right solution.

  • Computer Aided River Management, Murrumbidgee River
    A real-time fully hydrodynamic model of a 1600km river, providing river operators a current description of the state of the river and ensuring that the right amount of water, reaches the right location (both agricultural and environmental) at the right time. Models produce key catchment and river processes with real-time measurement, enabling natural tributary inflows and dam releases to ensure less water is lost to evaporation and evapotranspiration.
  • Gold Coast Storm Tide Decision Support System
    A modelling tool to run cyclone scenarios to produce inundation maps of a highly populated and complex system. The projects involving modelling resolution of timing and accumulated storage in multiple waterways to determine maximum water levels associated with a severe event to assist in aiding in emergency responses to severe storm events.
  • Kimberley Aquaculture Production Zone EIA and EMMP
    An Australian client wanted to develop aquaculture production and support potential producers by supply a suitable aquaculture site that was understood for conditions. This enables appropriate environmental measures and permissions to be put in place to facilitate maximum production of 20,000 tones/year with no adverse impacts expected on the environment. DHI undertook extensive hydrodynamic and biological field work to establish baseline conditions, followed by development of an ecological response model. The model was used to assess impacts from major pressures (nutrients, organic debris) on marine ecological components (i.e., local flora and fauna).
  • Dambreak Models
    DHI has undertaken numerous dambreak models, including assessment of 14 different dams in NSW to simulate propation of dam break flow and flood inundation extents.
  • Seaway Smart Release Decision Support System
    DHI investigated the environmental impacts of future releases of treated recycled water on a natural, complex estuarine waterway. Hydrodynamic variations were produced from spectral wave and hydrodynamic models and inserted in a high-resolution advection-dispersion models, subsequently the plume and its subsequent diffusion was tracked. An automated SmartRelease strategy was implemented to enable improved timing of releases to coincide with non-symmetrical fluxes out of the Seaway, improving the environmental outcome.
  • Groundwater Modelling, WA
    DHI are currently undertaking two significant groundwater modelling projects for the WA Department of Water (DoW). The projects involve development of groundwater modelling platforms for significant groundwater resource regions of WA. The modelling platforms will be integrated into the DoW’s planning systems to support decision making on future water resource development and management in these regions.
