How does a flood form?

Answer 1

It almost always starts with a huge amount of rain, but there are many things that help it along. If the ground is hard, then the water just sits on top, but if the ground is soft, the water seeps in. However there is only so much water that can be stored, and when the ground is full, it acts like a sponge and squeezes it all out. If you lived at the bottom of a hill, or a mountain Ext. it would be more likely to flood, because it is easy for the rain to run down. Another way a flood can start is when the rain flows into a river, and bursts the bank.

Answer 2

A flood forms when a large amount of rain falls over a long period of time. Constant hard rain for shorter amounts of time can also cause floods. The most common floods occur when there is more water volume than can be carried by the normal system of streams and rivers, and water escapes into the surrounding regions called flood plains. There are also Flash Floods, where a normally dry channel is suddenly and without warning filled with water from a heavy rainfall miles away, an event that usually ends in a relatively brief time.

Flooding is a natural phenomenon, the way that nature deals with the wide variations in rainfall that can occur in a given area. It is quite arguable that floods are not a natural disaster; the disaster is that people have been ignorant enough to build in natural flood plains, where there is near certainty that flooding will occur at some point in the future.

Answer 3

Floods occur when the drainage capacity of the soil is exceeded. Floods occur when too much rain falls for the soil to soak up quickly. Certain soils, such as clays, tend to flood more easily than others.

Answer 4

CAUSES

Rivers flood as a number of physical causes such as heavy rain fall for a long period of time( prolonged rainfall) heavy rain, snow melt and steep relief (mountainous land).

Answer 5

Floods, other than the Biblical one, are caused by too much rain, like monsoon season, or when a dam breaks.

Answer 6

They usually happen because of a lot of rain.

Answer 7

A flood occurs when there is too much water for the ground to absorb. Floods can be caused when too much water flows into a creek and the water rises above its banks.

Answer 8

Flooding can also be caused by tsunamis.

Answer 9

if you live at the coast
