Understanding impact dynamics on buildings caused by fluviatile sediment transport

摘要: Abstract Understanding the impact dynamics on buildings caused by complex fluviatile sediment transport processes and interaction with exposed elements is still a major challenge. Especially flood hazards large amount of mobilized sediments can cause severe damages to building structures located within flood-prone torrential fans. Mitigation efforts, be they rooted in spatial planning or local structural protection, may benefit from better insights into dynamics. In order gain understanding between buildings, physical scale model was set up at 1:30 measure forces comprehensively assess determining factors. This mirrors part fan Schnannerbach Torrent (Eastern European Alps, Austria). It includes its steep torrent channel adjacent floodplain, hosting equipped measurement devices wall three-dimensional process. The experiments indicated that depend mainly deposition floodplain are also influenced distribution structures, less intensities analysed events grain size distributions transported deposited sediments. results our study highlight need consider natural process built environment as well their mutual (shadowing vs. channelization) risk management.
