This is the second in a series of reports on short duration model studies conducted at the Mead Hydraulics Laboratory. The object of these model studies is to investigate the use and applicability of erosion control structures associated with the control and maintenance of river banks for the purpose of finding the most economical, effective, and environmentally acceptable solution. This particular study was initiated to find and identify information that would aid in our design methods. The study investigated hard point structures in S-shaped basin alignment under uniform flow and constant slope conditions. The specific objectives of the study were to determined: The recommended design for hard point structures to protect against failure; The effect of flows overtopping the structure; Whether the structures were equally effective in curved and straight channel reaches; The effect of structure alignment on the erosion pattern; The effects of varied spacing on the erosion pattern; and The effect of velocity and depth on the erosion pattern.
