Welcome to the October 2025 (and before) update:
This is the first installment of the monthly update of DebrisFrame. Some things where already mentioned in the monthly Avaframe updates. Here we will focus on the DebrisFrame specific stuff. So lets get started!
First functions relevant for simulating debris flows have been implemented in AvaFrame.
The DebrisFrame repository now contains a c1Ti module that executes AvaFrame’s com1DFA with overwritten parameters (https://github.com/OpenNHM/DebrisFrame/tree/master/debrisframe) . Until now DebrisFrame’s c1Ti module is only excecutable from a terminal (https://docs.debrisframe.org/en/latest/installation.html) .
Adaptive Topography
PR #1112 (https://github.com/avaframe/AvaFrame/pull/1112 ) provides the opportunity to adapt the surface when entrainment, detrainment or stopping takes place. The documentation can be found here: https://docs.avaframe.org/en/latest/theoryCom1DFA.html#adaptive-surface
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 .
Data A repository was created (https://github.com/OpenNHM/DebrisFrameData ) where you can find prepared reference scenarios for debris-flow simulations.
We continue to work:
- on enabling hydrographs to be used as input,
- on implementing alternative formulations for material entrainment (erosion),
- model testing.
