Canals can even be used to irrigate fields, and to help farmers with crops. For emergency flooding sandbags work well because they stop water from leaking through and the bags can be moved quickly and easily. My purpose was to see what the best way to reduce flood damage is. Even though levees worked well, they had a bad side effect. Sandbags did not work well.
Dams help move the water to a rural area, but the flood is worse there.
Canals helped, and reduced the size of the flood, but the flood still did damage. I am going to build five miniature rivers and make miniature levees, canals, sandbags, and dams. I will also have a control. Then I will create a six foot flood flood on a smaller scale by pouring the two cups of water in the river,inside medium sized boxes of Tupperware. I will then pour four cups of water in the Tupperware boxes.
