Comparison of 2-D Debris Flow Simulation Models : Implications for Practical Model Application to Hazard Assessment for Alpine Transport Infrastructure. : Poster presented 12th Congress INTERPRAEVENT 2012, Grenoble / France: Poster
The destructive impact of debris flows not only presents a threat to human settlements on alpine debris fans but also causes severe damage to alpine transport infrastructure (roads, railroad) on a regular basis, thus also endangering infrastructure users. In order to allow for infrastructure providers and responsible authorities to develop sophisticated hazard mitigation and risk handling strategies the potentially endangered road and railroad sections have to be identified. Here simulation models can serve as tools for the prediction of overall runout length and depositional behaviour of the transported water sediment mixture. Over recent years a number of 2-dimensional models for debris flow simulation have been developed, however no single accepted, reliable and easy to use standard model for the delineation of potentially endangered areas seems to have been agreed on yet. Therefore the objective of the presented study is to give a comparative overview of a defined set of available 2-dimensional debris flow simulation models with special respect to the requirements emerging from hazard assessment for alpine transport infrastructure. debris flow, 2-D simulation models, alpine transport infrastructure
