of water beyond its normal restrictions
For: Mr Frescura
By: Tyler Herbst
What Is A Flood?
Snowmelt Runoff - During the springmelt, huge quantities of water are released, which explains heavy spring runoff and flooding. This is called freshet.

Hurricanes - A tropical cyclone with winds of 64 knots or greater is called a hurricane.

Causes of Floods
There is also something good about floods, especially those that occur in flood plains and farm fields. Floodwaters can carry lots of nutrients that are deposited in the plains. Farmers love such soils, because they are perfect for cultivating some kinds of crops.

Economic - During floods (especially flash floods), roads, bridges, farms, houses and automobiles are destroyed. People become homeless. It usually takes years for affected communities to be re-built and for businesses to come back to normal.
Rainfall - when rainfall is so heavy that the ground is incapable of absorbing the water quickly enough, resulting in water staying above ground creating a flood.

Tsunami - when a giant wave from an ocean or large lake has so much momentum that it flows onto land and causes flooding and a lot of destruction.

Causes of Floods (continued)
Drainage Basins - the shape, size, soil type, and topography of the drainage basin are factors affecting the quantity of water reaching the stream.

Dam Failure - when the water force or level is too high and the dam collapses under the presure.
Causes of Floods (continued)
Effects of Floods
Floods can have devastating consequences and can have effects on the economy, environment and people.

Environmental - Hazardous substances end up in the water and eventually contaminate the water bodies. Flooding can kill animals, and others insects are introduced to affected areas, distorting the natural balance of the ecosystem.
People - Many people can be killed in floods. Many more are injured and others left homeless. Water supply and electricity are disrupted and people struggle and suffer as a result. Flooding brings a lot of diseases and infections including military fever, pneumonic plague, dermatopathia and dysentery.

Thank you for listening
My Thoughts/Solutions
-I think that more trees should be planted to help absorb and take in the water so there would not be water accumilating above ground.

-Levees (an embankment) can be made to raise the sides of rivers and to prevent water from overflowing.
