The recent increase in intensity and frequency of meteorological and hydrological events in mountainous areas is recognized as one of the effects of climate change. Extreme meteorological events endorse hydrological extreme events in steep channels, like flash floods, intense bed load transport, debris flows, and driftwood. Conventional defence works and their design criteria currently in use are erratic to ensure sufficient protection to human life and urban settlements. For this reason, new approaches need to be studied.
STEEP STREAMS project aims at researching structural innovative solutions and design criteria reliable to mitigate the impacts of flash floods and debris flows especially in presence of intense woody material transport, typical of mountain catchments.
