Abstract
We focused on a coastal structure of bamboo fence installed at the upper Gulf of Thailand, and tried to evaluate the performance of the fence in terms of wave damping. Moreover, laboratory experiments were conducted to find out effective arrangements of the fence. From the field survey data, wave damping ratios were approximately 20 % at the beginning. The performance of the ratio, however, was decreased due to the deterioration of the bamboos. The laboratory experiment data showed that wave damping ratios become up to 45 % in cases of shorter wave periods with longer wave dissipation distances and cross arrangements of modeled bamboo sticks. As wave periods become longer, the effectiveness tends to be less, and regardless of the dissipation distance and arrangement of sticks, the wave damping ratios are limited to the level of around 10 %.
