Stability of Gobi Block Revetment to Wave Attack.

Abstract

Tests of Gobi block revetment stability under wave attack were conducted at prototype scale in a large wave tank at the Coastal Engineering Research Center (CERC). Wave heights ranging from 1.6 to 3.2 feet and wave periods from 2.8 to 8.5 seconds were used. A 1 on 3.5 embankment slope was tested. Stability of the Gobi block revetment compared favorably with similar weight riprap on the same slope. However, a prototype Gobi block installation at Holly Beach, Louisiana, exhibited greater stability than the wave tank test. This increased stability is attributed to a dry mortar effect of sand and gravel wedged between the blocks.
