-runup defines storm inundation
-Dune erosion and beach recovery governed by swash zone conditions

Question 2

Runup

Answer 2

part of the time dependent fluctuation of the shoreline about the MWS
-value is given with respect to MWS
-SWS is when there are no waves
-MWS is the mean of the observed waves

Question 3

wave profiles
