We want 3Di to be used in a wide range of innovative applications, therefore we have made 3Di freely available for scientific researchers. The unique characteristics of 3Di make it suitable for climate impact studies, flood studies and hydraulic design of open channel and sewer networks, but also for estuarine and riverine studies.

3Di is a web-based, hydrodynamic model. The 3Di computational core includes a whole range of processes, including 1D cross-sectional averaged and 2D depth averaged surface water flow and groundwater flow. Moreover, it can deal with 1D sewer flow and structures like pumps, weirs and culverts. Many processes of the hydrological cycle are included as well. 3Di deals with numerous external forcings, like precipitation from radar images and wind.

The 3Di computational core is based on state-of-the-art numerical schemes. The computations make use of the so-called subgrid method. This technique includes high-resolution information in coarse resolution computations. This guarantees both accuracy and efficiency. The method also allows for accurate flooding and drying.

The in- and output of 3Di is fully GIS based and can be set up via QGIS or the QGIS-based Modeller Interface. This makes it easy to make models, analyse results and adjust your model accordingly.

What can you do with the 3Di academic license?

A research license grants you access to our 3Di computational servers using either the Modeller Interface or directly via the API. As the software needed to build your model and analyse your results is downloadable, this is the only thing you need to run your simulations.

In case of research which includes stakeholder participation we consider including the live site for your research license, this will be evaluated on a case by case basis.

These are our first steps in opening up our software to the research community, so if you have questions, suggestions or requests, please do not hesitate to ask.

What conditions do apply?

You work for a scientific institution and use 3Di only for research purposes. We have made a limited number of sessions available for researchers to share. A fair usage policy applies.

Commercial use is strictly prohibited. In case of a violation of these conditions, we reserve the right to revoke the license.

What do we expect from you?

We don’t really expect anything from you, but to share your research outcomings the way you are used to. In addition, we encourage you to share your experience in working with 3Di with us.

Where do I apply?

Send an email from your work address to info@3diwatermanagement.com including a summary of your research proposal and how you plan to use 3Di.

How to build a 3Di model?

Interested in what is needed to build your first model? Our documentation will lead you through all the steps. The documentation consist of the theoretical background, but also very practical tutorials. Regularly, we organise courses on 3Di.
