This engineering manual, "Coastal Groins and Nearshore Breakwaters", from the U.S. Army Corps of Engineers provides guidance for the design and placement of beach stabilization structures, specifically groins, nearshore breakwaters and submerged sills. Since the design of beach stabilization structures requires analyses of the wave, current, and longshore transport environments and the coastal processes at a project site, this manual can only provide guidance and design concepts in the area of beach stabilization. However, in addition to the general guidelines, the manual does present a compilation of the advantages and disadvantages of the various types of beach stabilization systems.
