The avalanche simulation model SamosAT is in practical application for the assessment of potential avalanche hazards since 2008. Step by step the tool has been further developed. The current software release 2015 of SamosAT contains new improvements, especially to optimize the modeling of the dense flow part. The new release focuses on enhancements in the numerical solution as well as on the modeling of avalanches by implementing new boundary conditions. Additional features are optimizing the handling of the program. This paper gives an overview of the main new features and procedures of the SamosAT update including first work experiences and recommendations for the practical application.
