Question

causes and effect of flood????​

Answer 1

Answer:

Causes of floods

• heavy rainfall
• overflowing rivers
• broken dams
• urban drainage basins
• storm surges and tsunami
• channels with steep sides
• lack of vegetation
• melting snow and ice

Effects of flood

• Agricultural lands are destroyed due to crops being submerged in water. This causes a lot of economic loss to farmers.

• They wreck houses, particularly kuccha houses in the villages.

• They cause disruption of all transport and communication.

• There is shortage of drinking water. They harm human, animal and plant life.

• They cause a rise in epidemics because of waterlogging. Malaria and diarrhoea are common diseases during floods.

• They cause decay of organic matter, leading to growth of infection-spreading germs.

• They affect the ecosystem in a negative way.

• They cause a lot of harm to the economy of the region.

Additional Information

Management and Mitigation of Floods:

• Floods cause tremendous destruction of life and property. But there are ways of protection against floods:

• If an area is prone to floods, houses in the region should be constructed on raised platforms. River banks should also be raised.

• Administrative authorities should properly map areas that are prone to floods.

• Rivers should be mapped and the surrounding areas appropriately prepared for floods

• Houses should be insured to protect against economic losses.

• Placing sandbags around houses can save property.

• Dams can be constructed to prevent against losses from floods. They control the water flow.

• Afforestation programs should be supported because depletion of forests is causing a rise in the number of floods witnessed almost every year across the globe.

• Rivers should be cleared of harmful garbage like plastics.

• Floods should be well forecasted and warnings systems should be in place.
