Wave attenuation in pile based breakwater
Objective:
To understand the wave attenuation pattern in pile based breakwater.
Apparatus used:
Wave flume tank, Piles, Inverter, Pump, Capacitance type elevation probes.
Description
Wave Attenuation is the change in wave transmission occurring when a wave passes through a permeable or porous medium.
Point the mouse on different parts of wave flume tank to know the names. Then click on next button to start the experiment.
- Wave generator : Bottom hinge flap type
- Motor : Inverter driven (11kW)
- Total length : 51.0m
- Depth : 1.5m
Choose spacing for placing the piles in a row.

Select the water depth
Select frequency and eccentricity by chosing wave period and wave height respectively from flume calibration table.
