r.avaflow is currently under development. All versions provided below should be considered preliminary and experimental and may not be used for risk management purposes.


r.avaflow represents a comprehensive open source tool for the simulation of two-phase mass flows and process interactions. Distributed under the GNU General Public License it is developed along two lines, each targeting at a specific group of users:

  1. r.avaflow [EXPERT] targets at researchers intending to conduct parameter studies or other types of computational experiments at a high level of complexity. It is designed as a module of GRASS GIS 7 and also employs the R Project for Statistical Computing. Thereby it allows for parallel processing and serves with various functionalities for visualization and validation within and across model runs. r.avaflow [EXPERT] is preferably operated in a non-interactive way and requires some computational skills and experience. It was tested on Ubuntu 12.04, 14.04 and 16.04 as well as on Red Hat 6.6 (Scientific Linux), and is supposed to work on most other UNIX systems.
  2. r.avaflow [PROFESSIONAL] is designed for practitioners intending to conduct back- or forward-calculations of particular mass flows. It is implemented as a multi-platform stand-alone tool. r.avaflow [PROFESSIONAL] is operated in an interactive way through a Graphical User Interface (GUI). It serves with a user-friendly interactive visualization function, but is not designed for complex computational experiments involving multiple model runs.

Please consult the manual of r.avaflow provided along with the code and the relevant publications before starting to use the tool. If you encounter issues not covered by the manual, you are highly welcome to join the forum on r.avaflow at landslidemodels.org.

Note that the efficient use of r.avaflow requires some computational skills. If necessary, please acquire the relevant knowledge on Linux, GRASS GIS, and GIS in general before starting to work with r.avaflow or posting in the forum.

Be aware that the application of computer models in the field of natural hazards is highly critical. First, all tools, data and manuals were prepared with utmost care and with the purpose to be useful - however, they may still contain errors of various types. Second, even the best models only produce a distorted and generalized view of reality. Their interpretation requires (i) extreme care, (ii) a detailed understanding of the model and (iii) complementary information such as measurements or observations. The unreflected communication of model results may lead to unwanted consequences. Whilst the authors highly appreciate critics or suggestions, they clearly refuse any responsibility for any adverse consequences emanating from the use of any of the versions of the tool provided below.

The latest releases of r.avaflow are available for download below. All details on the software requirements, installation procedures and instructions for use are provided in the corresponding manuals.
