Hazard mitigation effects of existing countermeasures by field survey and experiments

In the context of the examinations was found, that reasons for insufficient function fulfilment results from one for the structures unsuitable function, in the woody debris difficulties, in the geological qualities of the debris as well as in an inadequate discharge.

The result of the model experiments has been a strong coherence between the Froude-number and the maximum pressure peak occurring at the barrier. The pressure depends very much on the material properties, a significant difference was found between “fast and liquid” and “slow and stony” debris flows.
