hello guys , In this ppt you will learn about an future engineering project - flood protection underground mechanism.

1. Akido college of engineering
Final year b.tech project
Topic – “ flood water management”
submitted to –
Amit Kumar sir

2. An future civil engineering project .
Project related to – “Flood and Rain water recycle and
how to use it again”.
This project is submitted for the “project of b.tech 8th
semester”
submitted by – Tarun
Branch – Civil engineering
Semester - 8th (final sem)

3. Flood water enter in the city
• An Flood disaster occurs in japan , in June 2010 due to heavy rainfall
and about 155 peoples were killed and dozen's were missing.

4. 1. Theirs are many times flood and mudslide types of
disasters occurs in the coast countries like Japan
,china and India.
2. In 2005 a major flood occurs in the state of
Maharashtra ,Mumbai . In which 1094 people killed
and many more lost their homes and shelter.
3. The flood destroys the most of the coastal cities
because due to rise of water level in sea or river and
we have not any structure to protect our cities and
homes and even life of many peoples.

5. Flood control underground discharge
mechanism system -

6. Flood control mechanism system working and
planning -
• In recently 2019 a japan adopt this planning system in Tokyo to control the
flood disaster and prevent the lose of a home and life of the peoples.
• This project is very efficient and futuristic to control the water disaster like
flooding ,overflow from the rivers , In Tokyo the flooding occurs mostly so
this underground flooding control project is especially developed for this and
makes the city safe from water disaster.
• This project consists of 5 giant cisterns ,500 ton coloumns and more than 6.5
kilometres of cavernous tunnels which was all lie below the world largest
metropolis.

7. Cistern -
• This is an cylindrical cistern
which was built in underground
and the size of each shaft is
about 70m in height and 30m in
diameter.
• These cisterns are used to
collect the excess water from the
river during the flood.

8. Rectangular tank -
• This is an large rectangular tank
which having the size about
177m long ,78m wide ,and 18m
tall.
• The tank is used to take the
water from the cisterns though
the pressure control device.
• There are 59 pillars of 500tons
each support the ceiling and
break up the incoming water.

9. Turbine pumps -
• There are 4 large turbines are
used to pump out the water
into an area of the river that
take the overflow safely out to
sea.
• This turbines are powered by
jets for operation.
• The number of turbines required
is depends on the size of cistern
and the whole system.

10. The underground flood control mechanism-
Water taken from
the river
Thought the tunnels
water fill in cisterns
After break the flood
water is pumped into a
tank
After fill of the tank
then flood water is
allowed thought
The turbine which
covert M.E to E.E and
discharge to river

11. Use in India -
Major coastal areas where we use
this flood control underground
mechanism are –
1. Mumbai
2. Gujrat
3. Bihar
4. Uttrakhand
5. Jammu and kashmir
