A: I am writing about flood.

B: Cool. I write about drought. Can you tell me something about flood?

A: Sure. Flood is an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting in some of that water escaping its usual boundaries, or it may occur due to an accumulation of rainwater on saturated ground in an areal flood.

B: Oh! Do you know where do floods mostly occur in Vietnam?

A: Well, floods happen mostly in Hanoi and Ho Chi Minh city.

B: What are the impact of floods?

A: The primary effects of flooding include loss of life and damage to buildings and other structures, including bridges, sewerage systems, roadways, and canals.

A: How can people deal with floods?
