Stopping Tsunamis

Stopping Tsunamis | Science Fair Projects | STEM Projects
We're testing the effectiveness of tidal wave barriers. We'll build a tsunami simulator and use a man-made barrier and an artificial mangrove swamp to see which one absorbs the impact of tsunami waves better.


The hypothesis is that the artificial mangrove swamp will absorb the impact of tsunami waves better than the man-made barrier.

Method & Materials

You will set up a tsunami simulator using a water tank, sand bag, and pieces of plywood. You will drop the sand bag from the ramp and measure how far the wave travels on shore.
You will need a water tank of dimensions 2 meters x 1 meter x 0.3 meter, a sand bag that weighs 3 kg, pieces of plywood of various dimensions, enough water to fill the tank, a box of clay or play dough, 10 bricks, a protractor and a ruler.


The results showed that the artificial grass (representing the mangrove swamp) absorbed the impact of tsunami waves more effectively than the man-made barrier. This suggests that mangrove swamps are very effective in stopping the onslaught of tsunami waves.

Why do this project?

This science project is interesting and unique because it tests the effectiveness of different barriers in stopping tsunamis. It also shows how mangrove swamps can be used to protect coastlines from the destructive power of tsunamis.

Also Consider

Consider using a larger water tank with a greater depth, and vary the gradient of the shore.
