Revetment Stability Tests for Sargent Beach, Texas
The objective of this study was to investigate, via a two-dimensional (2-D) coastal model, alternate designs for the proposed revetment. Tests were conducted at a geometrically undistorted scale of 1:24, model to prototype. Based on test results, it was concluded that: (1) Four- to six-ton armor stone is stable for the maximum wave heights that can be expected to occur for 8- and 10-sec waves at still-water levels (swl's) of +4.0 to +14.0 ft mean low tide (mlt) with assumed scour depths of -3.6 and -8.6 ft mlt. (2) Stability of the original concrete blocks, which were 6.0 ft by 5.5 ft by 2.5 ft and had 0 percent porosity, was only marginally acceptable for the maximum wave heights that can be expected to occur for 8- and 10-sec waves at swl's of +4.0 to +14.0 ft mlt with an assumed scour depth of -3.6 ft mlt. (3) Several modified block plans were tested and it was determined that the optimum block size was 5.75 ft by 5.75 ft by 2.5 ft. These blocks, weighing 6 tons and having a porosity of 4 percent, should prove stable for the maximum wave heights that can be expected to occur for 8- to 10-sec waves at swl's of +4.0 to +14.0 ft mlt with an assumed scour depth of -10 ft mlt.
