New Publication about the tsunami-induced scour evolution around a square column

We're excited to share the research led by our colleague Dr. Alexander Schendel and his dedicated team. Published in Journal of Waterway, Port, Coastal, and Ocean Engineering, their study illuminates the pressing issue of tsunami-induced scour.

  • 🌊 Novel Laboratory Experiments: The team conducted innovative large-scale experiments at Forschungszentrum Küste incorporating unique boundary conditions, including a square coastal structure on a sloping, dry sandy beach, and simulated tsunami bores with single broken solitary waves.
  • Dynamic ScourProcess: The study unveiled the highly dynamic nature of the scour process, characterized by distinct phases of varying intensity and scour rate. The authors describe differences in scour development between wave runup and drawdown phases.
  • 📝 Influence of Drawdown Phase: Significantly, the drawdown phase was found to exert a substantial influence on scour development, contributing up to 58% to the overall scour depth. Moreover, sediment infilling during drawdown led to maximum scour depths twice those observed at the end of a test.
