Disasters may happen again  and again we need to act precisely to prevent them. Knowledge and understanding about the root causes of disasters is important because it can help us . One example of disasters is flood. We know the word flood but we do not know what are the root causes of it and how do it produced. We also need to know what are the difference between flood and flash flood.

Flood is just a plain rising level of water in land. Flood occurs when water inundates land that’s normally dry. This can happen in multitude ways. Most common, when rivers or streams overflow their banks. It takes hours or even days to develop and residents are given ample time to evacuate and prepare. Excessive rain, a rapture dam or levee, rapid ice melting in the mountain or even unfortunately place beaver dam can overwhelm a river and send it spreading over the adjacent land called flood plain.The flooding in coastal area occurs when a large storm or tsunami causes the sea to surge inland. Another reason why flood occurs because of clogged canals. Clogged canals triggers flooding because it stop the water from flowing which contributes to lessen the level of water in land.

While on the other hand,flash flood is rapidly rising and rushing water in land.Flash flood is caused by slow moving over the same area a heavy rains from hurricanes and tropical storms. Flash flood occurs through several factors. There are two elements, one is the rainfall intensity and the other is duration. Intensity refers to the rate of rainfall and duration is how long the rain last. Within a few minutes or hours of excessive rainfall, flash flood occurs. Since the water during flash flood is moving with  intensity, moving water has a destruction power. When a river overflow its banks, It can roll boulders,tear out trees, destroy buildings and bridges, can kill human lives, cars can be picked up and the water and landscapes can be contaminated with hazardous materials.
