Concept:

• One of the most common and dangerous natural disasters is flood. It also is the most widespread and the number one weather-related killer.
• A flood is the condition of too much of water in a certain area in a period of time.
• The water can come from many sources, rivers, seas, etc.
  Floods can be fast or slow rising, but most of them last for a quite long period of time.
• Scientists can predict them most of the time, but it’s not a guarantee.
• There are many different kinds of floods. They are regional floods, coastal floods, flash floods, river floods, dam-failure floods, mudflow floods, etc.
• The most dangerous of all is flash floods. Many people have died in flash floods. The reason we call it flash floods because it comes as a surprise, when the rain falls in an abnormally great rate. Thus, people don’t know about it and there’s not a high chance to survive. Most flash floods occur in warm seasons.
• Floods can occur in the areas, which are very far away from the storm or heavy rain.

Around The World:

Floods can happen anywhere in the world, even in the deserts. They can occur at anytime, day or night. Floods can happen more often in the low, flat areas, which are near or around the rivers. Floods have damaged many cities, and killed thousands of people. According to scientists, floods are the most common natural disaster in the United States in the 20th century. They have caused billions of dollars in damages all around the world.
