Sand container (SC) role in replacing 'hard material' in constructing defense structures has recently being applied and proven to have achieved the desirable performances. A few constructions using this new material have been constructed around the world. This report is written to conclude the finding on "Wave Attenuation Characteristics of Sand Container". Thestudy will focus on the wave attenuation by comparing the wave incident height and the wave attenuation height of these waves which known as transmission coefficient, Kt. A small scale model of sand container has been constructed using cotton fabric. The small scale model is a cylindrical shape with 8 cm of diameter and 30 cm in length. This study is divided into two phases andtotal of four (4) experiments have been conducted in this study. The study concluded that transmission coefficient, Kt increases with the increasing of wave period, 71, base width, 2?, water depth, d,f/d, freeboard, / However, transmission coefficient, Kt is decreases with the increasing of wave steepness, Hf/gT\ structure height, h, and d/gT2. However, in determining the best configuration, all theparameters need to be considered. The best configuration for the study will be theone that will give the lowest value of transmission coefficient, Kh andis 0.31 at wave period, T= 0.6 s, base width, B ~ 40 cm, water depth, d - 28 cm, structure height, h - 26 cm and freeboard,/- 2 cm.
