How Does Rain Cause Floods?

A flood can occur due to several reasons including heavy and intense rainfall. A number of other factors that can cause a flood include run-off from a deed snow cover, when the ground cant hold more water or over saturated soil, ice jams in rivers, urbanization or a lot of buildings and parking lot.

There are two types of floods, a regular river flood and a flash flood. A flash flood is much more dangerous and approximately 92 people die in flash floods every year. Flash flood is not caused particularly by rain but is always accompanied with heavy and intense rainfall.

Rain can cause a river flood and a flood in a city. As it rains heavily and continuously, the water level in a river starts to rise and goes over the edges of the river, which leads to a flood. In urbanized towns, a flood can occur due to heavy rainfall as most of the land has been covered with concrete. There is a very little soil land left to soak the water, which leads to saturated soil and causes a flood.
