3Di supports the modeler with an easy workflow for model building. Start with creating a schematisation of your water system in the Modeler Interface. Run simulations online in the cloud. Process results to create extra insights such as flood hazard ratings, damage estimates, and arrival times. Analyze simulations on- or offline.
3Di offers online, interactive simulations. It is designed for emergency response teams to gain a common understanding of a flood event and to try out measures to prevent and mitigate the impact of a flood.
We care a lot about the math and physics at the heart of 3Di’s hydrodynamic simulations. The computational core is carefully designed to create an optimal balance between accuracy, robustness, and speed.
Interact with the simulation as a team. Investigate and discuss the impact of prevention and mitigation measures such as placing levees, using retention basins, adjusting pump capacities or placing emergency pumps, closing pipes and orifices, or changing weir crest levels.
Our Open API is the most extensive API on hydrodynamic simulations in the industry. All features of 3Di are available in our API and can be integrated with your application.
3Di is able to simulate all processes in the hydrological cycle allowing the modeler to use 3Di in a wide range of applications
Flooding as a result of heavy rainfall. Options range from using simple rainfall timeseries to rainfall radar and forecast models. Thanks to the subgrid method, wetting and drying is automatically taken into account.
With the integrated calculation of surface- , sewerage - and freatic ground water flow it is possible to calculate the result of heavy rainfall in great detail and with high accuracy.
Fluvial floods and flows
In case of a high water wave in rivers, banks can be over topped, dikes can be breached and water is flowing in to surrounding areas. Using 3Di, not only the flood of the riverside area can be computed well, also the flow and the arrivalof the high water wave. Moreover, the after effects of the flood can be predicted as well. As for the drainage of the flooded area, the sewer system, small networks of canals and you hydrological balance are crucial.
Calamity flood models are models of areas that are prone to flooding events. Either due to heavy rainfall or for example due to the breaching of dikes and dams. Stakeholders, ranging from policymakers to emergency services, can simulate these scenarios. For dike breaching events, the breaches can be triggered at the location of the emergency and the breach will evolve in time. This for the most accurate prediction possible.
Water systems in urban and regional areas grow organically. Land use changes over time and the water system changes with it. Canal systems are build and sewer networks are expanded. 3Di helps to get insight in to such a complex system as it computes all interactions between different domain, such as surface flow, groundwater and the sewer systems. Tools supported by 3Di result, for example, the water balance tool and the…..assist users to get a firm grip on the system behaviour.
Urban planning is usually done by urban planners. With 3Di we have solutions that make it possible to convert a planning design to a 3D environment suitable for hydrodynamic calculations.
3Di can be used for sewerage design. Simply click in your design and test against predefined design rainfall events.
The cloud and API of 3Di makes it ideal for operational models. Every hour a model calculates whether it is necessary to start pumping a certain area to maintain the water level in a pumped drainage area.
The cloud and API of 3Di makes it ideal for flood forecasting models. As long as the model perfomance is sufficient any 3Di model can be deployed as a model in flood forecasting.
The original application of the subgrid method were estuarine and coastal areas. These areas are characterized by strong variations in bathemetry and generally the dominant forcing are the tides. This combination results in extensive flooding and drying and a strong dependence on the local bathymetry. The subgrid method makes it possible to get insight in the flow patterns in the small scale channel pattern that often surrounds such an area. Especially, for ecology and morphology this is crucial. The subgrid method, helps to connect the large and the small scale dynamics of these areas.
"What an MRI scan is for a neuroscientist, 3Di is to a hydrologist. A sophisticated cloud-based tool that delivers easy-to-understand visual output."

"The speed and accuracy of the 3Di model allows FloodSmart Parramatta to provide flood information quickly to the response agencies and the public so that they can prepare for flooding before it happens."

"The ability to run simulation on the spot when meeting clients is extremely valuable to use. We also love the flexibility to connect to other systems."

"3Di is a very strong visualisation medium, we apply it internally but also during external information sessions in which we explain to people how the water system in their area functions under a variety of different circumstances."
