Improper design & maintenance of drainage systems

Climate change

Rise in Population

Chennai Floods is a natural disaster of unprecedented scale

It provided lessons to improve urban planning & improve citys Governance

Unless you allow the drains to flow freely to the sea, water will be clogged & that is what unfortunately happened here

Union Minister for Environment & Forests, PrakashJavadekar

Chennai had about 600 lakes in the 1980s.

Now, only a fraction of the lakes are in a healthy

condition

Chennai Floods A direct result of unregulated

urbanization

Chennai has lakes with naturally-built flood

discharge channels.

We have built over the drains, blocking the flow

of water. We have forgotten the art of drainage.

A diversion from Buckingham Canal to the sea

could have saved the South of Chennai

A report by CAG (Controller and Auditor

General), 2008

Population has tremendously increased in the last decade

However, proper steps were not taken to cater the high population

To live, the residents of Chennai occupied the lakes and their drainages

Resulted in stagnation of water

Needs were also increased

Reaching to all the victims was impossible

Chembarambakkam Lake overflowed and it was opened overnight, without any pre-announcements.

Drainage of lakes were occupied by buildings

Tremendous population rise

Deforestation

Rise in Temperature

Improper or no pavement of lakes

All the transportation facilities were blocked

Schools and colleges declared holiday

Almost all the streets were flooded

Power supply was cut down from a day to a week

Shortage of food supply

Water scarcity

LOSS OF LIFE AND PROPERTY

Chennai can be further prevented from flooding by constructing structures using proper plans

Lakes should not be occupied by people

Drains of lakes should not be occupied

Lakes must be properly maintained

Flooding is a result of global warming

We must be ready anytime to face any disaster

Cities should be planned and constructed

Though Chennai Floods was devastating, it taught us humanity.
