| Description: | Miscellaneous Paper Abstract: A hydraulic model investigation was conducted at a geometrically undistorted scale of 1:5, model to prototype. The purpose of the study was to test the use of tree stands as a possible method for protecting levee embankments from wave wash caused by wind- and boat-generated waves. Incident wave heights ranging from 1.0 to 3.0 ft and wave periods of 2.0, 2.5, and 3.0 sec were tested on a total of 12 different test plans. The 12 plans covered a range of depths of tree stands using exclusively 4-in.- and 12-in.-diameter tree stems both with and without defoliated branch systems. The test results showed that for tree stems without branches the wave attenuation did not exceed a maximum of about 15 percent and on the average did not exceed about 9 percent. Tree stems with branch systems showed a maximum wave attenuation of about 45 percent, but the average wave attenuation did not exceed 15 percent. |
