Wave attenuation in pile based break water
Objective:
To understand the wave attenuation pattern in pile based wave flume.
Apparatus used:
Wave flume, Piles, Inverter, Pump.
Description
Wave Attenuation is the change in wave transmission occurring when a wave passes through a permeable or porous medium.
STEP
1
Wave flume characteristics
Point the mouse on different parts of wave flume 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
STEP
1
Choose spacing for placing the piles in two rows.
