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 flood barriers, 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 weather forecast models. Thanks to the subgrid method, wetting and drying is automatically taken into account. This makes 3Di very stable for these situations. 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, with high accuracy.
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 the flood and after effect of floods can be computed well. Including the flow and the arrival of the high water wave. As for the drainage of the flooded area, the sewer system, small networks of canals and you hydrological balance are crucial.
Area’s that are prone to flooding events can be digitized in calamity models. The calamity can be a result of 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 results in 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 such a complex system as it computes all interactions between the different domains. Tools supported by 3Di result, for example, the water balance tool and the watershed tool 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 computes all interaction between different domain, such as surface flow, groundwater and the sewer system. It can support the planning process in every step from the 1st design up to the final design. Iterative checking the climate resilience of the designs.
3Di can be used for sewerage design. The 3Di data models of the sewer system match asset management standards. 3Di aims for a seamless transition. Automatic transitions between pressurized and unpressurized flows make the simulation very stable. Simply click in your design and test against predefined design rainfall events. Check for optimal pump capacity’s using our interactive live side. For sewerage design 3Di is proven to minimize as much lead time as possible.
Used within areas like polders or hydrodams. The results of operational models are fed into process automation solutions and can trigger action. The API of 3Di makes it ideal to interface with these type of solutions. Types of action are start pumping a certain area or set the crest level of a weir to maintain the water level in a pumped drainage area. Open the spillway gates of a hydrodam to generate power.
Nobody should be surprised by a flood. New data sources like satellite data ensure a global coverage. 3Di is already able to define an accurate surface flow with a high resolution DEM. The API of 3Di makes it ideal to integrate flood forecasting models in dashboard applications. And with all delivered via the cloud it does not depend on strong hardware specifications. Any suitable 3Di model can be deployed as a flood forecasting model.
The original application of the foundation of 3Di, the subgrid method. These areas are characterized by strong variations in bathymetry and generally the dominant forcing are the tides. This combination results in extensive flooding and drying and a strong dependence on the local bathymetry. With 3Di it is possible to get insight in the flow patterns in the small scale channel pattern of such an area. For ecology and morphology this is crucial.
Create insights on the spread of substances and the age of water using the water quality module. In a fraction analysis, supply sources of water, such as pumping stations, inlets or water treatment plants effluent or an incidental discharge are marked as fractions. With 3Di It is possible to calculate from the water flow how the fractions are distributed spatially and temporally. The analysis can be further extended with an analysis of the age/residence time of the water
"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."

"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."
