Explanation:
A flood is an overflow of water that submerges land that is usually dry. ... Floods can also occur in rivers when the flow rate exceeds the capacity of the river channel, particularly at bends or meanders in the waterway. Floods often cause damage to homes and businesses if they are in the natural flood plains of rivers.

Flooding may occur as 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. While the size of a lake or other body of water will vary with seasonal changes in precipitation and snow melt, these changes in size are unlikely to be considered significant unless they flood property or drown domestic animals.
Floods can also occur in rivers when the flow rate exceeds the capacity of the river channel, particularly at bends or meanders in the waterway. Floods often cause damage to homes and businesses if they are in the natural flood plains of rivers. While riverine flood damage can be eliminated by moving away from rivers and other bodies of water, people have traditionally lived and worked by rivers because the land is usually flat and fertile and because rivers provide easy travel and access to commerce and industry.
Ways to Prevent flood
The government and citizens must work together to formulate ways to prevent floods. Proper awareness must be spread about the steps to take when floods occur. Warning systems must be set up so people get sufficient time to save themselves. In addition, areas that are more likely to have floods must have tall buildings above the flood level.
Further, there should be an efficient system for storing excessive water due to rain. This will prevent the overflowing of water. One of the most important steps is to strengthen the drainage system. This can avoid water logging which will prevent floods.
Other than that, dams must be constructed strongly. The use of cheap materials causes dams to break. The government must ensure there is a quality building of dams to prevent floods.
