Abstract

On several debris cones and alluvial fans a tendency of wealth moving into flood prone areas can be observed during the last decades, which results in an increased flood risk. So far, this trend was repeatedly overseen due to the parallel implementation of flood mitigation measures leading to a decrease of flood risk. Without the implementation of appropriate maintenance strategies, however, the effectiveness of flood mitigation, such as consolidation check dams, will decline over time. As a consequence, hazard risk patterns may remain undetected if the functional performance of protection measures is not assessed over their entire life cycle. To close this gap, recent findings regarding the damage susceptibility of consolidation check dams are reviewed and related future challenges for both research and practice are identified.
