| Abstract: | Abstract: This report is based on small-scale tests of riprap stability at a 1:10 (model: prototype) Froude scale, which replicate previous tests conducted in the large wave tank at the Coastal Engineering Research Center (CERC). The large wave tank tests used wave heights which exceeded 5 feet in some instances and can be regarded as prototype scale. Scale effects were approximately 20 percent at the zero-damage level, and the small-scale tests gave more conservative estimates of zero-damage wave heights and wave runups than those predicted from prototype test values. However, for severe levels of damage the differences between small scale and prototype were not as great. When profile surveys of severely damaged riprap were compared, the small-scale and the prototype profiles were found to have similar shapes. Wave period was also found to have less influence on the zero-damage wave heights in the small-scale tests than in the prototype tests. The results of these tests were compared with studies conducted by Dai and Kamel (1969), Thomsen, Wohlt, and Harrison (1972), and the Hydraulic Research Station (1975). |
