OPEN NATURAL HAZARD MODELING

This month in AvaFrame - February 2025 edition

Welcome to the February update:

As you might have noticed, we released two new versions this month:

-Version 1.10

-Version 1.11

So one includes the new geotiff capabilities, while the other one is a maintenance release to update the benchmarks.

So to emphasize this: due to the changes in the IO routines, the benchmarks have changed slightly! This is mostly visible in areas on the border of the flow or really strong gradients. However, the differences are well within acceptable ranges. But don’t take it from us, please see the attached report for the differences (version 1.11).


Release Version 1.11

We released Version 1.11

QGis users please note (after updating the plugin): do not forget to run Admin -> Update AvaFrame from within the toolbox to receive the updated core as well.

As mentioned in the previous release, there are some changes in the benchmarks, which are now updated:

This is a maintenance/benchmark release. We updated ALL benchmarks due to the IO changes in version 1.10. The report with the differences in v1.10 is attached as pdf.


This month in AvaFrame - January 2025 edition

Welcome to the first update of 2025:

Major work is being done of a change on our input side: we are including support for geotiff files. We will of course keep the asc format, but the geotiff format allows for a better integration and checks in relation to geographic information (i.e. coordinates, projections, etc.). Expect this to be released with a new version within the next weeks.

Work on the ISeeSnow paper is progressing nicely, as well as the work on our regional modelling project.


Release Version 1.10

We released Version 1.10

QGis users please note (after updating the plugin): do not forget to run Admin -> Update AvaFrame from within the toolbox to receive the updated core as well.

The path generation and geotiff release. So the main changes are:

  • The raster reading routines now accept geotiff files as well
  • we updated the automatic path generation, this will also end up in the QGis connector
  • added a new spatialVoellmy friction setup, to read mu/xi values from raster during initialization.
  • fix a long/long Windows bug (again…)
  • some plot can include a (online) background map

Please be aware: the module ascUtils is being deprecated. Please use rasterUtils which has the same functions in it. ascUtils will be removed in a future version.


This month in AvaFrame - December 2024 edition

Welcome to the December 2024 update:

Related to ForrestFrame 2 we are looking into different treatment of resistance forces, experimenting with existing approaches and ideas. A lot of work is going into the report of the ISeeSnow project, which we aim to publish next year.

And this is basically a repeat from last month: the regional modelling project is also coming along nicely.
Current topics are the splitting of larger input areas and efficient handling during computation.


This month in AvaFrame - November 2024 edition

Welcome to the November 2024 update:

We released a new version this month, please head over to [Version 1.9](https://github. com/avaframe/AvaFrame/releases/tag/1.9) to see the details.

A new friction model is available, the spatialVoellmy friction model. It allows to read mu/xi values from a raster during initialization. We included this for our project ForestFrame 2, which investigates the handling of resistance areas, i.e. forests, in com1DFA. Expect a few more changes in the upcoming months related to the treatment of this.


Release Version 1.9

We released Version 1.9

QGis users please note (after updating the plugin): do not forget to run Admin -> Update AvaFrame from within the toolbox to receive the updated core as well.

As is obvious by the long list below, this release contains plenty of bug fixes and internal improvements. The highlights are:

  • changes for small avalanche calibration in com2AB (in relation to the QGis Connector)
  • advanced installation instructions for Windows
  • functions to create probability maps from non-com1DFA results
  • plenty of com4FlowPy improvements and additional functionalities
  • option for detrainment (in resistance areas) for com1DFA
  • changes default range for propAna analysis

This month in AvaFrame - October 2024 edition

Welcome to the October 2024 update:

This month we are getting ready for our next release, which will contain quite a few things under the hood. And fixes a few things for the newest version of python modules.

Our intern hit the ground running and improved our documentation by adding a part about the advanced usage installation on windows. Head over to advanded installation if that’s relevant for you. Expect the next version to come out soon.


This month in AvaFrame - September 2024 edition

Welcome to the September 2024 update:

Work this month includes:

And we welcome a new intern , already tackling issues around documentation, ini files and more.

This month in AvaFrame - August 2024 edition

Welcome to the August 2024 update:

Again a slower month but with some work done on:

  • the ISeeSnow paper (we will contact all contributors by the end of autumn)
  • improvements on com4FlowPy
  • add detrainment more consistently
  • update com2AB code structure to fit our current style
  • fix and improve analysis plots
