Abstract: In recent years flow regulation by completed upstream reservoirs and project advancement to the refinement stage induced field investigations which isolated a major cause of bed roughness as a result of open spur dike systems within the concave bank control structures. To reduce the cause and effects, a new type structure was designed which consisted of a longitudinal structure designed along the concave alignment which partially closed the gap between the open spur dikes. Detailed design of this new structure called an "L-head" was varied in different areas to provide a basis for future analysis of field data to develop general design criteria. Realizing that this type of construction was still in its initial stage of development, a detailed laboratory design investigation using a model was requested. Such an investigation would provide faster results than prototype analysis and provide considerable savings over experimental construction of actual structures. An overall objective of the design study was to determine if a movable bed model could provide the engineer with sufficient information to be used as a working tool. Specific objectives were to provide data that would assist in answering the following questions relating to L-head structures. 1. What are the optimum design dimensions (length and height) of L-head structures? 2. What is the most economical construction sequence for L-head structures?
