Ribasim - v2026.1.1

This release makes allocation use adaptive timestepping by default, just like the physical layer.
That means users run into infeasible optimization problems less.
We also added support for multiple inflow links for UserDemand, so it can tap directly from multiple sources.
Besides that the Python package saw some performance improvements, and we squashed several bugs.

  • Support multiple inflow links for UserDemand. #3035
  • Adaptive timestepping for allocation. #3026
  • Add numerical documentation. #2994

Ribasim - v2026.1.0-rc1

This is the first pre-release running up to the stable v2026.1.0 release.
It is a release candidate, and we recommend most users to stick with v2025.6.0 for now.
We expect to make more breaking changes and add features before the final release.
This release sees significant performance increases for the core as well as the QGIS plugin, which especially help large models.
Route priority in allocation was added to steer the path taken by allocated water.

Breaking changes: In the Node table, source_priority has been renamed to route_priority, and the optional active column was removed.
Note that Ribasim Python will migrate existing models automatically, see also the new guide on updating Ribasim.
If nodes where set to inactive, they will have to be removed manually first.
The ribasim executable was moved to the bin subfolder, so users may need to update their PATH or RIBASIM_EXE environment variables.

Added

  • Add Windows installation script. #2682
  • Add ResidenceTime tracer. #2701
  • Add allocation route priorities. #2731
  • Document control by allocation. #2698
  • Document installing QGIS plugin from qgis.org. #2687
  • Add diagram for physical-allocation interaction. #2712

  • Improve database read performance of the core. #2762
  • Let run_ribasim use RIBASIM_EXE if set. #2783

Changed

Ribasim - v2025.6.0

This release brings significant improvements to the QGIS plugin, allocation, and CLI latency. The QGIS plugin is now published in the QGIS plugin repository and has a simplified UI; you can drag a TOML to QGIS to open a model. The black screen in the iMOD plugin is fixed in the latest version of the iMOD plugin, and the Arrow errors on loading results are also fixed.

Iteratively working on a model in a Python session has become easier now that model.<node_type>.add can replace existing nodes, and run_ribasim(toml_path) shows you live progress in all editors.

Breaking changes: There are two changes that shouldn't be breaking but might affect some users nonetheless. The input_dir default has been changed to "input". Python models now forbid any extra values in schema validation for stricter data integrity.

Added

  • Add run_ribasim(toml_path) convenience function. #2653
  • Allow replacing nodes with add API. #2664
  • Flow communication between primary and secondary networks. #2556

  • Add docs on reloading model in QGIS plugin guide. #2583
  • Document pandas requirement for QGIS plugin. #2642

Changed

  • Set input_dir default to "input". #2641
  • Python: Forbid any extra values in (base)model for stricter validation. #2595
  • Support Scientific Python SPEC 0 for broader compatibility. #2630
  • QGIS: Always use GDAL instead of pyarrow for better stability. #2591
  • Publish QGIS plugin. #2654 #2658
  • Improved build performance and compilation. #2652

Fixed

  • Finalize progress bar. #2665
  • Fix Junctions with subnetwork ID. #2633
  • Delwaq: Restore correct water/mass balance with Junctions. #2607
  • Delwaq: Limit endtime for partially failed Ribasim runs. #2637
  • Delwaq: Improved performance of flow boundary concatenation. #2597
  • Fix remaining DelWAQ netCDF warnings. #2621
  • Fix DataInterpolations integration bug. #2576

Ribasim - v2025.4.0

This release had a big push on the stability and performance for large models.
Users can now also provide a level-storage relation in Basin / profile.
This means old models need to be migrated by reading them into Ribasim Python, and writing them out.
We are working on reformulating the allocation problem.
Until this work is finished, allocation remains an experimental feature of Ribasim.

Added

  • Reload Ribasim model in QGIS. #2307
  • Support storage column in Basin / profile #2278
  • Allow Junction to Terminal links. #2295
  • Add model performance debugging guide #2308

Ribasim - v2025.3.0

The only breaking change in this release is to disallow connecting a single FlowBoundary to multiple Basins.
There are large improvements in the ability to visualize results on the map in QGIS.
We also welcome the Junction node to the family, which will help laying out networks in a recognizable manner.

Added

  • Add spatio-temporal results layers to QGIS. #2208
  • Add topological (straight line) link view toggle to QGIS. #2208
  • Added Junction node type. #2175
  • Write results and log bottlenecks also on an interrupt or crash. #2191 #2200

Ribasim - v2025.2.0

In this release, time is of the essence. We now support dynamic Pumps and Outlets, as well as DiscreteControl thresholds.
For each node, timeseries can be marked as cyclic, such that yearly recurring timeseries can be easily used without repetition.
We also developed tools to compare model input in Python.

The most visible change is the renaming of Edge to Link. Like always, existing models are migrated to the new version by reading them with Ribasim Python, and writing out the updated version. For now in Python model.edge will continue to work to ease the transition.

Added

  • Check Model equality in Python. #2057
  • Compare two models in Python. #2080
  • Support cyclic input timeseries. #2081 #2102
  • Time dependent greater_than thresholds in DiscreteControl. #2079
  • Validation error on connector nodes having the same from and to Basin. #2112
  • Support time dependent Pump and Outlet tables. #2110

Changed

  • Edges are now called links. #2023
  • All geometries are coerced to 2D. #2111

Fixed

  • Faster initialization of large tables. #2026
  • Declare incompatibility with Pandera v0.23+. #2120
  • Decrease the smoothing around Δh = 0 in ManningResistance. #2136

Ribasim - v2025.1.0

The first release of 2025 makes the Ribasim core more robust and stable, and speeds up
initialization for large models. The biggest new feature is the experimental support for
calculating tracers in Ribasim directly, which will hopefully make it easier to track where
the water resources are heading.

Added

Removed

  • Drop Python 3.10 support. #2012

Changed

  • Allocation: optimize per source. #1927
  • The Edge table no longer supports subnetwork_id; this is automatically inferred. #1956

  • ManningResistance is more stable around Δh=0. #1896
  • Fixes to Delwaq model generation. #1903 #1917 #1948

Natural Resources - Water Supply and Quality - Python
Published by deltares-service-account over 1 year ago

Ribasim - v2024.11.0

This major new release contains many improvements. A new formulation allows much smaller water balance errors, which is combined with several performance improvements. Ribasim Python does more validation that was previously only done in the core. The Ribasim QGIS plugin now sets the relations between tables for easier model inspection. Adding min_upstream_level and max_downstream_level to Pump and Outlet means DiscreteControl is often no longer needed.

The most significant breaking change is making the node_id and edge_id the index of the Node and Edge table; these need to be globally unique.

Starting from this release Ribasim is labeled as beta software. Since development is currently mainly driven by applications in the Dutch water system, we expect that addition work needs to be done for general use outside the Netherlands.

For coupled simulation with MODFLOW and/or MetaSWAP, this release is part of the iMOD Coupler, specifically release v2024.4.0

Added

  • Support discrete control based on an external concentration condition. #1660
  • Add results/solver_stats.arrow with solver statistics over time. #1677
  • Add icon to ribasim.exe on Windows. #1712
  • Save QGIS styling in the model database. #1713

Ribasim - v2024.3.0

For allocation we added a new LevelDemand node, and we now support a 'Basin / area' table to put polygons. The flow results now represent a mean flow from the timestamp until the next.

There were a number of breaking changes. See the associated pull request for upgrade information. Some were aimed at making the configuration options simpler. To navigate these changes better it helps to know what Ribasim version a model is made for, so we add ribasim_version as a required TOML key. The output files are also tagged with the version of the CLI that produced them. Adding extra columns with a meta_ prefix is still possible, but the prefix is no longer applied automatically to prevent accidental usage when a column name is not correct.
