Summary: | 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. |
