February 6th 2023

3Di Toolbox v2.5.0

A new processing tool is introduced:

  • Import GWSW HydX files to a 3Di Spatialite, including the possibility to download it directly from the server

The ‘Commands’ toolbox has been removed, and tools that are still relevant have been deleted or moved to the QGIS native Processing Toolbox (#715):

  • ‘Raster checker’ has been removed, as it has been integrated into Schematisation Checker (#710). Most checks in the raster checker are no longer relevant, because 3Di can now handle most of these cases.

  • ‘Schematisation checker’ is available from the Processing Toolbox > 3Di > Schematisation

  • ‘Create breach locations’, ‘Add connected points’ and ‘Predict calc points’ have been removed. These are no longer compatible with the latest sqlite schema version (214), where v2_connected_pnt, v2_calculation_point and v2_levee where replaced by v2_exchange_line and v2_potential_breach. Please use the 3Di Schematisation Editor for schematising breaches and/or setting the 2D cell with which ‘connected’ channels connect.

  • ‘Import SufHyd’ is available from the Processing Toolbox > 3Di > Schematisation

  • ‘Guess indicators’ is available from the Processing Toolbox > 3Di > Schematisation

  • ‘Control structures’ has been removed. Please fill the spatialite tables directly or upload a JSON file through the Simulation Wizard to use structure control.

Other improvements:

  • Processing algorithm ‘Computational grid from schematisation’ no longer remembers the input parameters from previous uses, because this was confusing (#723)

3Di Schematisation Editor v1.3

  • You can now add ‘Exchange lines’ to your schematisation to set the 2D cells with which a Channel should make 1D2D connections (#92)

  • You can now add ‘Potential breaches’ to your schematisation by drawing a line starting from a connected channel (#92)

  • Bugfix: editing attributes of referenced, not yet committed features (e.g. the connection node of a new manhole) now works without issues. #107

3Di Models & Simulations v3.4

The simulation wizard has been improved and some important additions have been made:

  • Boundary conditions timeseries can be uploaded as CSV files, so it is no longer needed to make a new revision when you want to use different boundary conditions. (#134)

  • Structure control can be set by uploading a JSON file (#313)

  • Upon completion of the simulation wizard, all data for the starting the simulation is sent to the 3Di API. This upload now happens in the background, so that you can continue working while the simulation is starting. (#389)

  • Because of this, the upload timeout can be set to a much higher value; please change this yourself if you after upgrading to the new version. The default upload timeout has been set to 15 minutes (#216). This is relevant when your simulation includes large files, such as laterals, dry weather flow, or 2D initial conditions.

  • Progress through the steps of the simulation wizard has been improved to only include the steps that you included in the ‘options’ screen before starting the simulation wizard. (#262)

  • The “Options” dialog that is shown before starting the simulation wizard has been reordered and clearly shows which options are available to the 3Di model you have chosen. (#261)

  • “Post-processing in Lizard” now has its own page in the simulation wizard. #432

  • Invalid parameter values for damage estimations (repair times of 0 hours) can no longer be chosen. #104

  • Forcings and events that cannot (yet) be added to a simulation through the simulation wizard, will now be preserved if they are part of the simulation template (#316). This applies to the following forcings and events:

    • Raster edits

    • Obstacle edits

    • Local or Lizard time series rain

  • When selecting a breach, the breach’s code and display name are shown on the map along with the id.

The schematisation checker in the “Upload new revision” wizard has been improved in the following ways:

  • The raster checker has been integrated in the schematisation checker (#412). Most checks in the raster checker are no longer relevant, because 3Di can now handle most of these cases.

  • You can now export schematisation checker results to a CSV file (#230)

Other changes and bugfixes:

  • The minimum friction velocity in new schematisations now defaults to 0.005 instead of 0.05 (#411)

  • A newer version (4.1.1) of the python package threedi-api-client is now used (#417)

  • If the maximum number of 3Di models for your organisation has been reached, a popup will allow you to delete one or more of them before uploading a new revision (#367)

  • Bugfix: in some cases, schematisation revisions could not be downloaded if “Generate 3Di model” had failed for that revision (#428)

  • Bugfix: prevent python error when attempting to start the simulation wizard with a template that has NULL as maximum_time_step value #418

December 8th 2022

3Di Toolbox v2.4.1

Due to changes introduced in v2.4, threedi-modelchecker would re-install on every startup. This has been fixed now. (#729) Fixed ‘Import sufhyd’: this routine expected the table v2_pipe to have a column ‘pipe_quality’, which was removed recently (#728) A schema version check was added to ‘Import sufhyd’. If the target spatialite has a too low schema version, you will be instructed to migrate it and try again (#726)

November 21th 2022

3Di Toolbox v2.4

  • Spatialite schema version compatibility upgraded from schema version 207 to 209 (#398, #406)

  • When downloading simulation results, the gridadmin.h5 file is now (also) downloaded to {3Di working directory}{schematisation}{revision n}grid (#403)

  • When downloading a revision, the gridadmin.h5 is also downloaded if available (#402)


Postprocessing Lizard

  • Added the possibility to use the projects in Lizard directly. Give your simulation as a tag: ‘project:number’ and the number will be added in lizard to the project.


  • The server known as inpy is no more. If you started using 3Di this year you can ignore this message. For the other users: the 3Di models cannot run anymore on 3Di Live. But the schematisations are all available. The be able to run the 3Di model again, simply look for your schematisation on management.3di.live and press ‘generate model’.

  • If you’re not sure whether your model is generated using inpy, go to management.3di.live search for your model. If there is no details page available (link is greyed out) then the model is generated via inpy.

August 2022

3Di Toolbox v2.3

  • Visualise any computational grid (gridadmin.h5 file), using the new Processing Algorithm “Computational grid from gridadmin.h5”. This works for gridadmin.h5 files that were generated on the server as well as those generated locally.

  • Generate the computational grid for your schematisation in the 3Di Modeller Interface. The routine that is used on the server to generate the computational grid, has now also been made available locally, so that you can continuously check how your schematisation is translated to a computational grid.

  • Migrating spatialites to the newest schema version now follows the same logic in all plugins: if a migration is required, a popup message will ask you if you want this. If you click Yes, migration will be performed immediately. (#377)

  • Some users experienced SSL Errors, caused by expired SSL certificates that are not properly removed by Windows. A popup message with specific instructions on how to fix this issue now appears when the error occurs. (#379)

  • When creating a new schematisation based on an existing spatialite, all rasters will be copied into the new schematisation. In the previous version, only the rasters referenced from the global settings were copied. (#375)

  • Installation and update procedure has been improved. Black command prompt windows are no longer shown on startup. (#621, #625)

Documentation on the Watershed Tool can be found here.

3Di Schematisation Editor v1.1.1 - EXPERIMENTAL

  • Migrating spatialites to the newest schema version now follows the same logic in all plugins: if a migration is required, a popup message will ask you if you want this. If you click Yes, migration will be performed immediately. (#50)

3Di Schematisation Editor v1.1 - EXPERIMENTAL

This is a new plugin that will make editing schematisations much easier than before.

What does this plugin have to offer for modellers?

  • Directly edit all layers of your schematisation, using all native QGIS functionality for editing vector features

  • Quickly add features to your schematisation with the “magic” editing functionality for 1D layers. For example: existing connection nodes are used when drawing a pipe between them, new connection nodes and manholes are created when a new pipe is digitized, etc.

  • Easily move nodes and all connected lines using the smartly pre-configured snapping and topological editing settings

  • Easily move the start or end of pipes, channels, culverts, orifices, weirs, pumps, and the connection node id’s will be automatically updated for you

  • Get a complete overview of your schematisation: all rasters that are part of your schematisation are added to the QGIS project when the schematisation is loaded

  • Spot the tiniest local variation in elevation with the hillshade layer is automatically added on top of your DEM

  • Visualise the mapping of (impervious) surfaces to connection nodes and change them by updating the geometries

  • Easily navigate through your schematisation: layers in the layer panel are neatly grouped together in collapsed groups

Version 1.1 is ‘experimental’ plugin, because it is not yet fully integrated with the other components of the Modeller Interface. In practice, this mainly means that you will have to convert between the Spatialite and the Schematisation Editor’s Geopackage format every time you start or finish editing your schematisation.

New in version 1.1 (for those users who already tried out version 1.0):

  • Facilitate adding channels and cross section locations (also fixes the issue that sometimes it was not possible to fill in channel start or end node ids)

  • Delete referencing features

  • Release through plugins.3di.live as experimental plugin

  • Rename to 3Di Schematisation Editor

  • Set scale dependent visibility for manholes

  • Fix export to spatialite in QGIS 3.22 (was fixed by adding a schema migration in threedi-modelchecker)

  • Fix drawing of pipe trajectory over existing manholes

  • Consistent handling of geometry edits

  • Check write permissions for Geopackage target location

  • Support spatialite schema_version 206 + updated the popup message if schema is not up to date

  • Remove field cross_section_code

  • Remove table cross_section_definition

  • Make all id fields autoincrement

  • End all editing sessions when user clicks Save to Spatialite

  • Rename column calculation_pnt_id of connected_point to calculation_point_id

  • Pump capacity should be NULL by default

You can access them through Processing > Toolbox > 3Di > Schematisation. In the future, these processing algorithms will replace the current checker tools available in the ‘Commands’ Toolbox.

February 2022 (Klondike)

We have released threeditoolbox 1.31 and 3Di Models & simulations 3.0.2. “3Di Models & simulations” is the new name for what was previously called “API client”. Please note: If you continue to use the old route, you still need the previous version of the plugin as well.

We have also released a new version of the Modeller Interface: Download here the latest version: Modeller Interface

August 2021

We have released a new version of the Modeller Interface with the following:

  • Update on the animation toolbar

  • Added tooling for dry weather flow calculations

  • Water depth maps for multiple timesteps

  • Bugfix Sideview Tool

Download here the latest version: Modeller Interface

Important note for QGIS Users

Please note that installing QGIS has been undergoing some changes, at the moment the OSGeo4W Network Installer is the recommended way to install QGIS. See https://www.qgis.org/en/site/forusers/download.html for more information. This change does not apply for users that use the Modeller Interface installer.

Animation Toolbar update

The styling of all animation layers has been improved. The value categories are no longer fixed but based on the value distribution in the entire simulation. In the 2D domain, the animation toolbar now visualizes cells instead of nodes. Furthermore, the option ‘relative to timestep 0’ was introduced. This allows you to switch between e.g. absolute water levels and water level relative to the start of your simulation.

Below are examples of a dike breach. Animation 1 is showing relative change in water level and discharge. The plot is done for every calculation cell and flow line. Animation 2 is the same situation as an absolute plot showing the water level per calculation cell and the discharge over the flow lines. Some other improvements to the toolbar include:

  • More user feedback.

  • The animation layers are removed when the Animation Toolbar is deactivated.

  • The groundwater layers are only displayed when the simulation includes groundwater.

Dry weather flow calculator

In some cases it is required to add dry weather flow to a simulation. To enable this a processing tool has been added to convert dry weather flow as defined in the model spatialite (dry weather flow attribute of the impervious surface layer) to lateral discharge timeseries that can be used as in your simulations. In our earlier API (v1), dry weather flow was read automatically from the spatialite and calculated according a standard distribution. In the current API (v3), dry weather flow is added as lateral discharges to allow for more flexibility. E.g. in the distribution of dry weather flow over the day.

Water depth maps for multiple timestep

We have added the option to generate water depth/level maps for a range of timesteps. The output is a multiband geotiff, where each band contains the water depth map of one timestep.

The water depth processing algorithm also has various minor bugfixes and improvements:

  • Selecting DEM layer from project no longer gives an error.

  • Generating outputs for timestep 0 without moving the timestep slider no longer gives an error.

  • Improved readability of LCD display by adding days to the display.

  • Set LCD value to 00:00 when file is loaded.

  • More accurate description of what the tool does.

Bugfix SideView tool

The SideView tool no longer worked since QGIS 3.16.6. This has now been fixed

May 21st 2021 - 3Di API QGIS Client

We have released a new version of the Modeller Interface and an update of our 3Di API QGIS Client to version 2.4.1. The following has been fixed:

  • Users no longer get a throttling warning when trying to start a simulation.

  • Results download only shows results for the model that is selected in the panel.

The location of plugins has changed from https://plugins.lizard.net/plugins.xml to https://plugins.3di.live/plugins.xml

April 22nd 2021 - 3Di Toolbox

We have released a new version of the Modeller Interface and the ThreediToolbox 1.18 . This is a fix for the error “Couldn’t load plugin ‘ThreeDiToolbox’ due to an error when calling its classFactory() method ModuleNotFoundError: No module named ‘alembic’ “

April 1st 2021 - 3Di Toolbox

Due to some changes under the hood in QGIS 3.16 we have released a new version of the Modeller Interface and the ThreediToolbox 1.17

March 8th 2021

Download the latest version of the Modeller Interface , which at the time of writing uses QGIS 3.16.4. For QGIS users: upgrade the plugin using the plugin panel. In case this doesn’t work, it is possible to install the plugins as zip file. The latest versions are ThreediToolbox 1.16 and Threedi-API-QGIS client is 2.4.0.

Local calculation of water depth & water level maps

It is possible to generate water depth maps for every time step with the newest version of the Modeller Interface. To generate these water depth maps, 3Di applies a special algorithm that combines the water level results with the information of the DEM. This algorithm creates visually appealing maps. The maps show the water level and water depth results on high resolution, these can be based on the interpolated and on the non-interpolated water level results.

A quick guide to generate water depth maps:

Processing ^^> Toolbox ^^> 3Di ^^> post-processed results ^^> water depth

Or check out our documentation: 3Di Processing Algorithms

Extended support for starting simulations using the Modeller Interface

We have added the following support for starting simulations from the Modeller Interface:

  • added support for wind. See our user manual: Simulating with the 3Di Modeller Interface or our technical documentation : Wind effects for more information.

  • added option of tags. This can be used to tag a simulation with a project related tag. This way it is easier to organise simulations.

  • added time-interpolation options for laterals

  • added the option for Netcdf upload for rain

  • option to set base URL for the API (for use of 3Di in other countries)

The following bugs have been fixed:

  • start time is now correctly used

  • search window for models is now case insensitive

  • bug fix lateral file upload

Bugfix in the ThreeDiToolbox

  • Fix import sufhyd coordinates swapped on newer gdal versions.

February 22nd 2021

  • We now support QGIS 3.16 for our toolbox.

Please not that the Modeller Interface is not yet upgraded to QGIS 3.16, we will do so when the QGIS repo’s are updated.

For QGIS users: upgrade the plugin using the plugin panel.

3Di Modeller Interface styling improvements

Based on your feedback we have improved the styling of the schematizations in the Modeller Interface. Not only that, we now have support for multiple stylings! Check out the video to see how it works.

The improvements are:

  • For weirs, orifices and culverts, the styling now indicates when flow in one or both directions is impossible (discharge coefficient - 0)

  • Grid refinement styling now indicates the refinement level

  • Multiple stylings are added next to the default. Switching to these stylings allows you to visualize flow direction, code, id, storage area, bank level, reference level, invert level, crest level, diameters and dimensions, min/max of timeseries, and pump capacity. How it works is explained in the docs: Multiple styles per layer

Schematization checker improvements

We are constantly working on improving the 3Di experience. Based on user experience analysis we have added the following checks to the schematization checker:

  • Add check ConnectionNodesDistance which ensure all connection_nodes have a minimum distance between each other.

  • Set the geometry of the following tables as required: impervious_surface, obstacle, cross_section_location, connection_nodes, grid_refinement, surface, 2d_boundary_conditions and 2d_lateral.

  • Add check for open cross-section when NumericalSettings. use_of_nested_newton is turned off.

  • Add checks to ensure some of the fields in numerical settings are larger than 0.

  • Add check to ensure an isolated pipe always has a storage area.

  • Add check to see if a connection_node is connected to an artifact (pipe/channel/culvert/weir/pumpstation/orifice).

Bugfixes in 3Di Modeller Interface

  • Fixed h5py error, it is now possible to use the 3Di toolbox on QGIS 3.10.12

  • Fixed x-axis bug in the water balance tool
