More detail would be beneficial to help explain the approach used in the system. How will the runup methodologies be utilized to develop a 50-year coastal flooding projection. It appears that no methodology exists. The database should include various shoreline features, such as date-time, bluff line, scarp lines, vegetation lines, shorelines. The areas around harbors should contain considerably more detail.
Lesser detail seems necessary in undeveloped stretches of the shoreline.
Parts of a preliminary methodology were presented in the workshop for doing a 50-year erosion prediction scenario. A test of the value of system should be undertaken. That is, compare the FEPS projection of erosion over 50-years to the erosion predicted from simply extrapolating data, i.e. recession rates determined from sequential aerial photographs.
