Short summary
Short summary
This paper investigates the relationship between El Niño Southern Oscillation (ENSO) and coastal hazard risk in the U.S. Pacific Northwest (PNW) using probabilistic simulations of climate patterns, weather patterns, and coastal hazard drivers. Results indicate there is a weaker relationship between ENSO and PNW coastal hazard risk than suggested by observations. These findings advance understanding of ENSO dynamics and support climate-informed hazard management.

Short summary
Short summary
In this work, we examine a set of observed extreme, non-earthquake-related and non-landslide-related wave runup events. Runup events with similar characteristics have previously been attributed to trapped waves, atmospheric disturbances, and abrupt breaking of long waves. However, we find that none of these mechanisms were likely at work in the observations we examined. We show that instead, these runup events were more likely due to energetic growth of bound infragravity waves.

Short summary
Studies of the impact of storms on dunes typically focus on the importance of dune elevation,
here we analyze the protective services offered by the dune height and width, the morphology
of the beach fronting the dune, and artificial dune construction via the use of sand fences.
We find that dune volume loss most strongly correlates to beach width rather than dune shape,
although when beach width is controlled for low and wide dunes offer greater protection than
tall and narrow dunes.
Studies of the impact of storms on dunes typically focus on the importance of dune elevation,...
