Welcome to the October 2025 update:
October brought new friction models to com1DFA, better documentation for our MoT-Voellmy module, and several improvements to configuration and analysis tools.
New Rheological Models
PR #1169 (https://github.com/avaframe/AvaFrame/pull/1169 ) added rheological models for debris-flow simulations to com1DFA. This extends AvaFrame’s capabilities from snow avalanches to debris flows. The implementation updates the Cython force computation functions, adds new configuration parameters, and includes documentation at https://docs.avaframe.org/en/rheologicalmodels/theoryCom1DFA.html#rheological-models .
Documentation Updates
PR #1196 (https://github.com/avaframe/AvaFrame/pull/1196 ) expanded the com9MoTVoellmy documentation with details on input/output specifications and setup instructions. The update also fixed the autodoc configuration (replacing autosummary_mock_imports with autodoc_mock_imports) and improved API references.
Configuration Changes
PR #1197 (https://github.com/avaframe/AvaFrame/pull/1197 ) and PR #1198 (https://github.com/avaframe/AvaFrame/pull/1198 ) renamed “FromShp” to “FromFiles” in the INI configuration files. This better reflects that AvaFrame reads various file formats, not just shapefiles.
Analysis Tools
PR #1190 (https://github.com/avaframe/AvaFrame/pull/1190 ) updated ana3AIMEC to handle cases where reference or comparison data contains only zero values. The module now skips plot generation in these scenarios instead of creating empty or misleading plots.
Dependencies
PR #1194 (https://github.com/avaframe/AvaFrame/pull/1194 ) added explicit temporary dependencies (gdal, libgdal, geos, proj) to pyproject.toml to address installation compatibility issues.
Furthermore we took part in the Snow.is conference in Iceland. Have a look at O3.1 in the proceedings for our contribution.
And another huge development we are quite happy about is the inclusion of NGI’s MoT-Voellmy in the QGis Connector plugin. This is currently still in experimental mode, but we are looking forward to get feedback and improve the plugin. We are in close communication with people from the NGI and SLF regarding the calibration of the MoT modules.
And last, but in now way least, we contributed to a paper which finally got published in NHESS . Thanks at Michael Neuhauser for the great work!
See you in November!
