Abstract:

The model of the subsurface pipe structure is designed as a reducer of the height of an incident wave generated. Part of the wave will be reflected, and some will be transmitted through the pipe structure. Experiments on the calculation of reflection and transmission coefficients on the subsurface pipe structure model were carried out with variations in the depth of water in the flume. This experimental study aims to determine the effect of changes in incident waves on variations in water depth above the subsurface pipe structure (d-h = 0.0h; 0.1h; 0.2h). This research was conducted at the Hydraulics Laboratory of the Department of Civil Engineering, Faculty of Engineering, Hasanuddin University. Experimental laboratory research method using a wave generator flume with the characteristics of the generated waves consisting of 3 variations of the period (T=1.0 seconds, T=1.1 seconds, T=1.2 seconds) with three variations of water depth (d) which used, i.e., d=1.0h; d=1,1h and d=1,2h, where h is the height of the pipe structure. The results of this study indicate that the deeper water above the structure, the smaller the reflection coefficient and the greater the transmission coefficient.
