Question

How do floods adversely affect India?

Answer 1

Hint: A flood occurs when water overflows and submerges normally dry terrain. In the sense of "flowing water," the term can also refer to the tide's inflow. Floods are a study area in the subject of hydrology, and they are a major problem in agriculture, civil engineering, and public health.

Complete answer:
Flooding can occur as a consequence of an overflow of water from a water body, such as a river, lake, or ocean, where the water overtops or breaks levees, allowing some of the water to escape its regular confines, or as a result of rainwater accumulating on a wetland in an area flood. While seasonal fluctuations in precipitation and snowmelt will affect the size of a lake or other body of water, these changes are unlikely to be deemed important unless they flood property or drown domestic animals.
Floods have a negative impact on agricultural areas, destroying crops, killing people, destroying homes, and wiping out livestock.

Floods has the following adverse effects:
- Large swaths of agricultural land are being swept away, and crops are being flooded as a result of river erosion, sedimentation, and inundation caused by floods. During floods, the agriculture sector is the most affected. Waterlogging in farming areas is the most serious harmful effect of floods on agriculture.
- Floods hurt or kill people, and floodwater is frequently contaminated with sewage, causing sickness and affecting clean drinking water.
- The power supply has been disturbed.
- Businesses are being pushed to close.
- Hospitals and schools close their doors.
- Flood damage to bridges, trains, and roadways affects transportation networks.

Note: When the flow rate of a river exceeds the capacity of the river channel, particularly near bends or meanders in the waterway, flooding can occur. Floods in natural floodplains of rivers can cause damage to homes and businesses. Flood damage caused by rivers and other bodies of water can be avoided by moving away from them.
