Question

What are some facts about floods?

Answer 1

Coastal floods are caused by bad weather, especially when it coincides with high tides,or by huge waves,tsunamis,that form at sea.

River floods are caused when more waters enter them than they can discharge.The usual causes are heavy rain or snow-melt water.Ice jams can temporarily dam a river  and release a torrent of water when they give way.Artificial causes include altered river courses,

deforestation resulting in increased run-off and burst dams.

Sudden torrential rain,concentrated in a narrow chaneel can produce flash flood.

Because so many people live near rivers(all the ancient civilisations floorished on river banks only), flooding is one of the most destructive geological hazards to humans for centuries.

But there are some benefits also due to floods.An example of the benefit of regular river flooding is the creation of fertile silt in the fields all along the Nile river before the construction of the Aswan High Dam in Egypt.

Answer 2

There are two main factors to a flood, 1) too much rain in one area, 2) excessive snow melt with warmer temperatures. One added note, if the river is small the flood is coming quicker.

Answer 3

Having once helped carry a refrigerator through waist deep flood water, I can tell you that floods are wet.  Of course it was raining at the time, so that didn't help.  Most floods are created by heavy rain.  Brisbane, Australia, 26 January 1974.

Here is another.  When buying land, avoid the cheap low-lying places.  Hillsides and tops are rarely flooded.  My parents were once offered a house not far form a river and in a slight depression.  My mother refused to get out of the land agent's car because she said it could flood.  The agent denied it, of course.  

A few years later they bought on a hillside nearby and we saw the first house completely submerged by floodwater.  Brisbane, 26 January, 1974.
