In an earlier post (Feb 26, 2019) I highlighted some work using statisitics from lidar data sets along with SLR to define the risk of shoreline locations and to use that to define how to vary renourishment volumes to maintain a chosen equilibrium beach width.

Now working on Sullivan’s Island beach that has very distinct trends and no history of any significant renourishment I decided to try another way to capture the trend aspect as the primary variable. The white paper highlights a way of taking historic shorelines to the next level of analysis. This model of historic and future shoreline morphology is based on the use of shorelines and multiple sets of lidar data; the model can be run forward and backwards in time and used for a wide variety of analyses.
