The Modeller Interface is the interface for the hydrology experts. This interface is used to build models, edit models, start simulations and analyse results. The Modeller Interface is a customised QGIS installation with dedicated plugins for the use of 3Di. This setup allows users to benefit of all processing power of QGIS combined with custom made tools supporting 3Di. Since a 3Di schematisation consists of a compact database (currently spatialite format) and rasters users have a great deal of freedom in building their model. And when finished there is no import/export necessary, the spatial dataset is the schematisation.
We have chosen QGIS as our supporting platform to build, edit and analyse the 3Di models and the results for the following reasons:
QGIS Technology allows you to use the power of hundreds of GIS processing tools
Combine web maps (aerial, topo, osm and may others) and model schematisations
It offers almost unlimited styling options styling options
It is a highly customisable interface
Option for building own plugins to interact with model (results)
It is an open source platform.
You can find the downloads and instructions of the Modeller Interface in this section: Modeller Interface installation.
The 3Di Live Site is the interface where users have live insight in the results of their simulation. Not only that, they can also interact with it. This interface is perfect to create a shared understanding of the watersystem. Scientific papers on this can be found here
A short introduction of 3Di.live
The 3Di API is the center of the 3Di Ecosystem as it allows all interactions of users and forcings. The 3Di API is accessible for users. It is a more advanced way of modelling, but it gives you lots of flexibility and can speed up projects. We give here some examples of applications, where it can be usefull to interact directly using the API.
Batch simulations: run hundred different rain events
Automated testruns & results checking & adjusting a model and run it again
Run 3Di in an operational setting
Use Jupyter Notebooks to run, download and analyse 3Di simulations. Examples can be found on the : threedi github repository
Design your own control for weirs or other structures
The current production API of 3Di is v3.
The Modeller Interface is used to build and edit you model schematisation on your own computer. However, the 3Di models are stored in the cloud, to enable version control. When uploading a model it is stored in the so-called 3Di Model Database. Users upload their model with a description of the adjustment being made. Colleagues can synchronise their models on their own laptop and continue working with the improved version.
The Management Portal can be used to monitor running simulations, download results, manage 3Di models, schematisations and simulation templates. With our portal we aim to provide our users with the necessary information to run day-to-day tasks within a web browser.
