Answer:
Flood is a natural disaster caused due to natural events like rain, storm, cyclone, etc. Whenever there is a rainfall it fills the rivers, lakes and other water reserves. These reserves have a capacity to carry water, which depends on their physical parameters like – height of the embankment and the number of bends, in the case of the river. Now, if a river or lake receives water beyond its sustaining capacity; it will naturally throw the excess over its bank, onto the plains. This is flood and the whole process is called flooding.
However, even a relatively small amount of rainfall can cause flooding of a congested or low lying area. This type of flooding is mostly seen in urban areas during the monsoon. Excessive construction of roads and buildings has altered the level of the plain, making it non-uniform, kind of high-low type which causes water to accumulate in a particular area.
