The type and scope of work accomplished and responsibility and authority of the office to which he is attached is indicative of the interests of an author and of the information available to him. It is therefore pertinent to cover in this general section a summary of the responsibility and the delegated authority of the Corps of Engineers as regards Coastal Engineering. The subject of recent advances in coastal structures is quite broad and complex and modern design practice incorporates old and new findings. This paper discusses various aspects of proper modern design of breakwaters and jetties with special attention to newer findings, their proper application and the means by which the findings were made. The Corps has the responsibility for the planning, investigation, design and construction of Federal civil works navigation projects. This consists generally of harbor and channel works. Their responsibility extends to the control of all works, private or governmental, to assure that navigation will not be adversely affected. They are also charged with the responsibility of planning, investigation, design and construction of Federal civil works projects involving shore protection from wave and currents, protection from effects of hurricane, tsunamis and tidal flooding, and of beach erosion control. The accomplishment of such a mission therefore includes research of an applied nature to permit advancement in knowledge and technique. Most of this research is based on small scale model studies accomplished at the U. S. Army Engineer Waterways Experiment Station at Vicksburg, Mississippi, and at the laboratory of the Corps of Engineers Beach Erosion Board in Washington, D. C. In addition a limited number of prototype studies are being initiated in the charge of the staffs of various District Engineers.

In the last few years, we have had the opportunity to study a number of prehistoric Caddo Indian sites in the Ouachita Mountains of southwestern Arkansas through conducting archeological surveys of more than 2700 acres at three lakes constructed and managed by the U.S. Army Corps of Engineers, Vicksburg District. The three lakes are DeGray Lake on the Caddo River, Lake Ouachita on the Ouachita River, and Lake Greeson on the Little Missouri River. Our purpose in this article is to summarize the archeological character of the prehistoric Caddo sites in these three different parts of the Ouachita Mountains. We focus in particular on the material culture record of these prehistoric Caddo settlements—especially on the ceramic sherds found on them—and discuss when these sites may have been occupied by Caddo peoples.

A phased study of the dike fields within the Vicksburg and Memphis Districts of the US Army Corps of Engineers was conducted to document the channel morphology trends since dike construction on the Lower Mississippi River (LMR). This included the development of the hydrographic survey database and methodology utilized to identify changes in channel geometry in response to dike construction. A subsequent report will provide further refinements to the approach and results of the comprehensive assessment. Recent Mississippi River Geomorphology and Potamology program efforts have employed the database developed by Mr. Steve Cobb to assess the geomorphic changes in 21 dike systems along the LMR. Previous studies using this database have indicated that the dike fields have not caused a loss of channel capacity. Furthermore, these efforts suggested that the trends in the dike fields are closely related to the long-term geomorphic trends along the LMR. Previous efforts using the Cobb database provided considerable insight into the dike effects on the LMR, but they were limited spatially and temporally. In this study, a database and protocols were developed to allow for a more robust assessment of dike field impacts and to extend the spatial and temporal extents of the analysis.
