Recent flood events in Switzerland and Western Austria in 2005 were characterised
by an increase in impacts and associated losses due to the transport of woody
material. As a consequence, protection measures and bridges suffered considerable damages. Furthermore, cross-sectional obstructions due to woody material entrapment caused unexpected flood plain inundations resulting in severe damage to elements at risk. Until now, the transport of woody material is neither sufficiently taken into account nor systematically considered, leading to prediction inaccuracies during the procedure of hazard mapping. To close this gap, we propose a modelling approach that (1) allows the estimation of woody material recruitment from wood-covered banks and flood plains; (2)
allows the evaluation of the disposition for woody material entrainment and transport to
selected critical configurations along the stream and that (3) enables the delineation of
hazard process patterns at these critical configurations. Results from a case study suggest
the general applicability of the concept. This contribution to woody material transport
analysis refines flood hazard assessments due to the consideration of woody material
transport scenarios.
