1. List some examples of water damage and how humans try to prevent damage.
Information: floods, avalanches and tsunami. And I also know how human try to prevent these damages.
I need more examples. Can you give me some more and also tell me how humans to prevent those?
2. Do any of the ways in which humans try to prevent damage caused by water create other problems? Select few examples and discuss.
Information: Humans try to prevent floods by building levees and dikes. I just know two.But I don't know how levees and dikes create problems. But I can tell you how peole build them. Here:
Levees, long walls of earth, are built along the banks parallel to a river. They are designed to keep the river contained during flooding.
Dikes protect land that has been reclaimed from the ocean. Poeple also bulid dikes around their houses and towns when a flood threatens.
Thats all I know. Except this, I need more examples and how they create problems.
Please help me!!!
