Book Description
Tests of riprap stability under wave attack were conducted at prototype scale in the large wave tank at the U.S. Army Coastal Engineering Research Center (CERC). Wave heights ranging from 1.4 to 6 feet and wave periods ranging from 2.8 to 11.3 seconds, were used. Three embankment slopes, 1 on 1.5, 1 on 3.5, and 1 on 5, were tested. The riprap stone was a diorite placed on the embankments by dumping. The median stone weights of the riprap ranged from 27 to 120 pounds. The study showed that wave period, because of its influence on breaker characteristics, has a significant effect on riprap stability. Wave conditions which produce the lowest riprap stability are predictable and are associated with a collapsing-type breaker.

Book Description
Test data on the stability of dumped quarry stone riprap to wave attack is presented and analyzed. The tests were conducted in the large two-dimensional wave tank at the Coastal Engineering Research Center (CERC) at near prototype scale. The test data show riprap stability changes with wave period with the lowest stability occurring at a period that creates a collapsing breaker. Methods to predict riprap stability and wave runup on riprap are developed and discussed. (Author).

Book Description
This report describes the wave tank tests and field performance of a single layer of large armor stone used as a protective overlay on underdesigned riprap. The resistance of the overlay to wave attack was determined by small-scale model and prototype-scale wave tank tests at CERC. A stone overlay concept was successfully used to repair a damaged riprap revetment on Oahe Reservoir, South Dakota (App. A). Design information and an example problem (App. B) are presented to demonstrate application of the overlay concept to both revetment repair and original construction. (Author).
