Beach Migration into Protected Developed Land

I ran a scenario where I protected the developed land.  Instead of all of the developed cells staying constant, I and am seeing some beach migration into those cells.  It's not a huge change in the results (about 3% of my developed area is lost in 1m SLR by 2100) but strange none the less. I am attaching a figure showing the results.

Hi Anna,

Are you using the overwash module (i.e. do you have a value in the parameters for the 'frequency of overwash')? Based on the figure you sent, it looks like the results you are seeing are due to overwash calculations. You might try re-running the simulation with the frequency of overwash set to zero unless you have site-specific data for storm frequency and effects.

Hope this helps. Please let us know if you have any other questions.
