What is flood ?
Floods
⚫ A flood is an overflow of water that submerges land which is
normally dry. The European Union (EU) Floods
Directive defines a flood as a covering by water of land not
normally covered by water.
⚫ Floods usually cause large-scale loss of human life and wide
spread damage to properties. This damage is known as flood
damage.
Why floods occur ?
⚫ Firstly, it occurs due to heavy rain and storms
during the monsoon season that leaves a lot of
rainwater behind on land
⚫ This may in turn cause flash floods, where
floods move at great speeds, causing
destruction and casualties
⚫ A flood occurs when water overflows or inundates
land that's normally dry. This can happen in a
multitude of ways. Most common is when rivers
or streams overflow their banks. Excessive rain,
a ruptured dam or levee, rapid ice melting in the
mountains, or even an unfortunately placed
beaver dam can overwhelm a river and send it
spreading over the adjacent land, called a
floodplain.

Maharashtra including large areas of the metropolis Mumbai a city located on
the coast of the Arabian Sea.

Casualty and Damage
 Loss of life
At least 500 people lost their lives in the flashfloods and the landslides.
• 24 deaths caused by a stampede which occurred due to a false tsunami
rumor at a slum in Vile Parle.
• Residents of low lying coastal areas, who had faced the floods just 48 hours back,
panicked and rushed towards higher ground.
• 16 deaths due to trapped vehicles from suffocation in cars after water levels
rose rapidly, preventing escape.
• 12 deaths due to Electrocution, 5 due to Wall collapse, 25 most deaths were
due to water borne diseases.
 Medical Care and Hospitals

personnel were damaged by flooding
