DebrisFrame - The Open Source Debris Flow Framework

State-of-the-art hazard analysis for debris flow processes requires the use of complex numerical models, the further development of which must follow both the latest scientific findings and adaptation to the findings of engineering practice. The DebrisFrame project is developing the foundations for a debris flow modelling framework based on the digital simulation tools of the open avalanche simulation framework AvaFrame. The principles of the development environment are openness of source, user-friendliness, comprehensive documentation and recommendations regarding a practice-relevant parameterisation. The focus of the developments is primarily on operational applicability in Austria, while at the same time laying the foundations for the academic requirements of training and research. On the basis of AvaFrame, functions for special mudflow modules/tools will be created on a similar basis to AvaFrame. Data of debris flow events from selected event documentation and current monitoring stations are systematically processed and serve as reference events and benchmarks for model testing. DebrisFrame will serve as a basis for the further development of an operational debris flow model for engineering practice. The project represents a significant innovation in the field of debris flow simulation. The improved determination of process areas and occurring forces supports the determination of exposure and vulnerability in risk management.
