Science Projects With Flood Models
Use a shallow box and some clay to build a basic flood model. Just make sure
to leave room for a river down the center of the box, and build up the edges of
the river to represent the land. If you'd like, add several smaller rivers, or
tributaries, leading into the river. Then, fill the river entirely with water
and tip the box slightly, while having a partner pour additional water into the
top part of the river.
You can easily add "levees" by building up the sides of the river with clay.
Just make a thin wall around the river, and then try the simulation again.
Observe the difference in water movement. You can use this flood model to
demonstrate the importance of levees around rivers.
Some types of soils are more conducive to flooding than others. Test various
types of soils by putting them into a coneshaped piece of filter paper held over
a cup, and pouring a set amount of water over each one. Measure the amount that
drains through the soil into the cup. (You may want to do two runs of this step
one while the soil is dry, and one while it is saturated.) Based on your
results, consider which soil would be most likely to flood.
Although this project only addresses one aspect of a flood model, it can be
used as a precursor for a bigger project. Using a similar process to the flood
valentino uk sale model, make three different models of a river, each using a different type of
soil to surround it. Then, test the three models to see which creates the
biggest flood.
Using a flood model, you can test various types of levees. Even areas that do
have levees can sometimes flood. For example, the levees that collapsed during
Hurricane valentino uk Katrina were mostly Iwall levees, and after the flood many of them were replaced
with Twall levees. Research the differences between Iwall levees, Twall levees,
and earthen levees and create each of them using Popsicle sticks, clay, or other
craft items. Test the effectiveness of each, and draw conclusions about which
type of levee is optimal for various conditions.
