The catchment of the torrent Naarn shows a high degree of forsted area and therefore a huge amount of woody debris can be mobilized during floods.
Further downstream this material can cause clogging effects at culverts and bridges, as it could be seen during the flood of 2002 in the municipality of Perg.
The goal of the study is to test a new filtering structure that has been developped by students within the lecture of structural exercises.
