Wave attenuation in vegetation based break water
Objective:
To understand the wave attenuation pattern in vegetation based wave flume.
Apparatus used:
Wave flume tank, 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 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
STEP
1
Choose among the following.
STEP
2
Choose among the following options
| Wave height | |||||||
| 6 | 8 | 10 | 12 | 14 | 16 | ||
| Wave period | Frequency | Eccentricity | |||||
| 2 | 9.8 | 6.5 | 9 | 11.2 | 14 | 16 | 18.1 |
| 1.5 | 13.48 | 5.1 | 6.3 | 8 | 9.5 | 11 | WB |
Wave period = 1.5s, Frequency=13.48Hz
Wave height = 8cm, Eccentricity=6.3
Make a note of the frequency and eccentricity values.
STEP
5
Set the frequency and eccentricity in the inverter and pump respectively.
Frequency you have chosen = Hz
Eccentricity you have chosen =
Scroll to set the eccentricity
STEP
6
Click on start button on the inverter to start wave generation and observe the wave pattern.
