“…Hinsdale Large Wave Flume (LWF) in Corvallis, Oregon, and slowly increased the intensity of the storm conditions over time to match these inner surf zone characteristics. This facility is further documented in (33). This flume is the largest in the United States and is a key facility as part of the U.S. National Science Foundation's (NSF) Natural Hazards Engineering Research Infrastructure (NHERI) program.…”

Does vegetation accelerate coastal dune erosion during extreme events?

A broadly accepted paradigm is that vegetation reduces coastal dune erosion. However, we show that during an extreme storm event, vegetation surprisingly accelerates erosion. In 104-m-long beach-dune profile experiments conducted within a flume, we discovered that while vegetation initially creates a physical barrier to wave energy, it also (i) decreases wave run-up, which creates discontinuities in erosion and accretion patterns across the dune slope, (ii) increases water penetration into the sediment bed, which induces its fluidization and destabilization, and (iii) reflects wave energy, accelerating scarp formation. Once a discontinuous scarp forms, the erosion accelerates further. These findings fundamentally alter the current understanding of how natural and vegetated features may provide protection during extreme events.
