Purpose

Data were collected in cooperation with the U.S. Army Corps of Engineers (USACE), Detroit District, to define beach topography and near-shore bathymetry areas that have been scoured by high water levels and wave activity. This post-placement survey was completed to evaluate movement of placed material and overall changes to the barrier island and surrounding nearshore area.
