OPEN NATURAL HAZARD MODELING

Call for abstracts IMC 2022

We cordially invite you to submit abstracts to our focus session about

Gravitational mass flow simulations for avalanches

at the International Mountain Conference 2022 in Innsbruck, Austria, on September 11-15.

The call for abstracts is currently open and will last until February 16. IMC 2022 will be held in a hybrid format, more info here: modes of participation .

We look forward to many fruitful discussions and exchanges!

Kind regards,

This month in AvaFrame - December 2021 edition

Welcome to our last monthly update for 2021.

This month so a broad development across all modules:

  • A new module ana4Stats/probAna is available and is concerned with all things related to probability runs and it therefore includes a lot of tools for parameter variations as well. This lead to some general improvements regarding filtering and ordering of simulations, both before any simulations are run, as well as for sorting and filtering results for postprocessing.


This month in AvaFrame - November 2021 edition

Welcome to our monthly update for November.

There are some changes especially for those wanting to try and test AvaFrame:


This month in AvaFrame - October 2021 edition

Welcome to the first winter edition of the monthly update!

This has been a month with a lot of internal development, but not much of it landed on the master branch just yet.

The topics we are tackling at the moment are:

  • investigation of the initial particle distribution, we are trying different options and check to see if there is a significant change in the results. Aim is to make this easier to reproduce and less arbitrary.


This month in AvaFrame - September 2021 edition

We’re back from summer! And with some exciting news too!

Version 0.6 , the QGis/pypi and testing - release, was published.

So what is included in this release?

  • The installation process was completely changed and (hopefully) made a lot easier for you:

    • installation of AvaFrame is now working via pypi , i.e. through pip install avaframe.
    • the pip install is provided for Windows, Linux and MacOS for python versions > 3.6. Note that we did not test MacOS (anyone got a free Macbook lying around?! :-); seriously: if you work on MacOS we’d be happy about some feedback!)
    • the QGis connector plugin is now in the public QGis plugin directory and installable via the QGis plugin manager. This allows you to run the standard operational workflow from within QGis.
    • see our installation instructions for more information
  • Our testing / code coverage has improved considerably. We are still long ways away from perfect, but this is an ongoing process. As a side-note: we switched from codecoverage to codeclimate as service provider, since we felt we gain more insights this way.


Public prototype and monthly update

In case you wondered where your beloved monthly update is, it was delayed due to us working on a big announcement:

We released version 0.5 , our so called public prototype.

So now why is this big? (Apart from being a project milestone, which you couldn’t care less about I guess)

This is the first release that is being tested for application in operational hazard mapping.

To achieve this, quite a few things changed:


Monthly public meeting

We invite you to join our first monthly public update meeting on

Tuesday, 15. June, 9:30

via this link: online meeting (bigbluebutton, i.e. in your browser) .

These meetings are meant to allow you to see what is currently going on in our development and we invite you to give feedback or suggestions.

We start with a flash update in which everyone working on the project gives a quick (2min) overview about their current work. Afterwards we go into detailed discussions on agenda topics. Feel free to contribute if you want to!


This month in AvaFrame - May 2021 edition

Welcome to the May 2021 edition of our monthly update. Our main goal was the preparation for the switch of the dense flow model com1DFA from a C code to python (cython) code. This meant to check every little detail and difference that we found as well as:

  • updated the documentation for the new python com1DFAP: algorithm, workflow and description

  • updated the re-projection method of particles. Now particles are re-projected normal to the surface and not vertically. This is especially important at sharp drops. We also added a test case for this.


This month in AvaFrame - April 2021 edition

Welcome to the April 2021 edition of our monthly update.

Apart from the release of version 0.3, we put a lot of effort into our python/cython dense flow avalanche module com1DFAPy, targeting a swap with com1DFA within the next month:

  • com1DFAPy now includes:

    • an additional particle initialisation method: the per depth method

    • the option to use secondary release areas. They are being triggered if particles enter the area of a secondary release area.


Release version 0.3

We just released version 0.3 - The AIMEC and Windows release -

This release brings an AIMEC refactor, plenty of improvements related to the test cases and Windows capabilities. 3 new idealised/generic test case are included: flat plane, inclined slope and pyramid.

Com1DFAPy recieved a lot of advancement as well, e.g. parts of it are converted to cython to speed up computation times.

Documentation regarding our testing is included, see more at the testing page.
