Description:	Technical Memorandum From the Preface: An important aspect in consideration and design of shore improvement measures is the resulting effect on the beach of placing smooth-face walls in the zone reached by wave action. In many cases such walls may produce severe scour and loss of the beach both behind the wall as well as in front of the wall. This memorandum presents the results of a laboratory model study to investigate the equilibrium beach profile resulting when vertical walls of various top elevations above or below the elevation of the undisturbed water surface (relative to incident wave height) were located in the beach zone and subjected to wave action. As might be expected walls of highest relative top height, by allowing less energy to pass over the wall, resulted in greatest scour in front of the wall, while lower walls resulted in increased scour dimensions behind the wall. Effects of wave steepness and grain size of beach material were also investigated. It is believed that the results of this investigation could prove useful in considering practical problems involving vertical-face walls, although care must be exercised in interpretation for prototype use as appreciable scale effect may be involved.
