Erosion rates are typicall...A - Really hard to say. Erosion rates are typically determined in terms of distance per year based on long-term comparison of shoreline positions, whereas bluff failure events are typically rare and catastrophic. So even if an area has relatively low long-term annual rates of erosion, the bluff can retreat significantly in high wave/high rainfall storm years (such as El Nino years), interspersed with little to no retreat in calm years. For example, the USGS estimates long-term erosion rates in this area of around 0.6 ft/yr. Many scientists believe that we will see increased rates of erosion in the future due to accelerated sea level rise, so for argument let's just say we might see 1.0 ft/yr in this area over the next century. The Ritz looks like it would be in serious trouble with, say, 50-60 ft of retreat. So without any further armoring of the bluff, maybe 50 years or so? But don't quote me on that - I don't want to get any calls from the Ritz!Justin Vandeverhttps://www.blogger.com/profile/08677455267312712386noreply@blogger.comtag:blogger.com,1999:blog-4246436115275908122.post-30979699651068875972013-03-19T23:45:42.531-07:002013-03-19T23:45:42.531-07:00Cool shots!
