Issues of Damning and Flooding essays My research project is on the issues of damming and flooding. This research project will explain to you why people create dams, what types of dams there are, and what is the effect that a dam makes on the land. Also this project will explain to you what causes flooding and how it affects the land and everything around it. It will also explain how to prevent and protect yourself. Finally this paper will explain to you how to stop flooding and how to protect your house from it. Dams are created for many different reasons. They can be created to slow down the flow of a river or they can be created to produce electricity and collect drinkable water. The reason some dams are created is to decrease and slow the flow of water in a river. This is done because some rivers can become so high that they are always over flowing even during a small rainstorm. The most important reason that dams are built is to make hydroelectricity. Hydroelectricity is electricity made by turbines being pushed by water. There are many different types of dams in the world that fit different situations better. The first type explained to you is a gravity dam. Gravity dams are dams that can withstand the force of a large horizontal wall of water. This is used to cover large spaces that need to have a lake behind them. The Hoover Dam in Boulder, Nevada is a gravity dam. Another type of dam is an arch dam. Arch dams are suitable for small narrow canyons where there is a need for a dam. Another type of dam is a buttress dam. Buttress dams are dams are dams that have very thin walls held up by buttresses. They are used more often because they cost less and use fewer materials then the other two types of dams. Dams are helpful to humans yet hurtful to the environment. Dams can totally destroy the environment that they are built in. They change the natural rivers and make them in to unnatural lakes. Dams can change the water salinity level in t...
