ABSTRACT
The mountain torrents of the Brienz area are well known for their flooding and debris flows for hundreds of years. In the year 1896 disastrous debris flows occurred in the Lammbach rift valley which destroyed several houses in the village Kienholz, along with the track of the Swiss Federal Railway. The volumes of the last three incidents have been reported as approximately 300,000 m3 of material covering land along a shoreline length of 120 m with an average debris thickness of about 2.5 to 4.0 m.
