This science fair project was conducted to evaluate the effectiveness of two types of tidal wave barriers: Which best reduces the onslaught of tidal waves in a natural disaster? A man-made barrier (reconstructed from clay) or an artificial mangrove swamp (reconstructed from plastic grass)?
The artificial mangrove swamp will absorb the impact of tsunami waves better than the man-made barrier.
Tsunami, volcano eruption, earthquake, landslide
The materials required for this science project are as follows:
1. For this science fair project, the independent variable is the type of barrier used (a man made barrier and an artificial mangrove swamp). The dependent variable is how far the wave travels on shore. The distance that the water travels should be measured using a ruler. The constants (control variables) are the size of the water tank, the size of the sand bag, the weight of the sand bag, the slope of the shore line and the slope of the drop ramp.
2. The tsunami simulator is set up as in figure 1. The 0.6 meter x 1 meter piece of plywood is used as the land gradient. It is tilted at 30° and fixed in place using the clay. The 1 meter x 1 meter piece of plywood is the drop ramp from which the sand bag falls. It is fixed using clay at the other end to the tank. It is tilted at 60 °.
It was observed that the water traveled the shortest distance inland when the artificial grass (representing the mangrove swamp) was used.
The hypothesis holds true: the "artificial mangrove swamp" absorbed the impact of tsunami waves more effectively than the man-made barrier.
Use a larger water tank that has a greater depth.
