Why is/did

Thailand Flood?Y07 - Humanities Water Assessment Step 12011


2/10

It all started up in a few cities in the north. After urgent

attempts of trying to block the floodwaters, it couldnt be

stopped. The water overflowed the bank of the Yom and Nan

river, which are 2 of the many tributaries for the Chao Praya.

The water also overflowed the Bhumibol and Sirikit dams, which

eventually had to be let out.

After that one action, the water was able to fight through

barriers, creating a huge crisis for Thailandthe 2011 Floods.

All of this happened because


3/10

Reason 1:

-----------------------------------------------------------------------------------------------

CAUSE FOR THE REASON: CLIMATECHANGE

INCREASED AMOUNT ON MONSOONS AND PRECIPITATION/

RAINFALL IN 2011.

This is considered a reason

because it increases the

amount of water inThailand, which is why

floods happen.

The problem with the rain

is that it is too much, and

has no where to go.

The more precipitation

there is, the more

evaporation, condensation

and accumulation there is.

4/10

Reason 2:

-----------------------------------------------------------------------------------------------CAUSE FOR THE REASON: INCREASED

PRECIPITATION (REASON 1)

THERE WAS AN OVERFLOWING AMOUNT OF WATER IN DAMS.

This is considered a reason because

it causes flooding in the flood plain,cities and homes near the rivers.

The Bhumibol and Sirikit dams

(which are located in the north) are a

major cause to why it is/was

flooding.When dams are let out, they flood

areas which are not meant to flood.

Rivers start to overflow in this

situation, because of the massive

amount of water let out from dams.

The more water there is let out

from the dam, the more water

there is that needs to travel

through the tributaries,

meanders, mouth, delta and to

the sea. This also causes the

water level for the sea to rise.

Reason 3:

-----------------------------------------------------------------------------------------------

CAUSE FOR THE REASON: INCREASEDPRECIPITATION (REASON 1) and

RUBBISH CLOGS DRAINS

NOT ENOUGH/UNAVAILIBLE DRAINAGE FOR THE OVERFLOWING

WATER.


because it prevents the water

from flowing into somewhere

else.The water should be flowing

into drains, but since there is

too much water, more than

how much the drains can

afford, the water overflowsonto the roads. Rubbish that

has been floating around also

goes through the drains,

using up more drainage

space.

Rubbish clogs up the drain, andwater is overflowing:

Reason 4:

-----------------------------------------------------------------------------------------------

CAUSE FOR THE REASON: SUPPORTSTHE ECONOMY and FUFILLS OUR

WANTS/NEEDS

US HUMANS HAVE BUILT ROADS, DAMS, BUILDINGS, AND CANALS/

KHLONGS/BODIES OF WATER PREVENT THE WATER FROM FLOWING.


because it blocks natural flood

paths, and the natural flow.

Since we build roads, dams,

buildings and bodies of water,

which is basically creating a city, we

do as much as we can to protect it.

This obviously prevents the water

from directly flowing through

cities, to the gulf of Thailand, wereit is supposed to go. Building all

these things supports the economy

very well, makes our lives

complete, but makes it harder to

create a path for the water to flow

to.

Reason 5:

-----------------------------------------------------------------------------------------------CAUSE FOR THE REASON: SUPPORTS

THE ECONOMY and FUFILLS OUR

WANTS/NEEDS

US HUMANS HAVE CUT DOWN MOST OF OUR NATURE, NOT

ENOUGH TO SOAK UP THE PRECIPITATED WATER, AND WE USEDAMS INSTEAD.

This is considered a reason because it

doesnt help the amount of water decrease.

When there is a flood, the main goal is to

get rid of it. Our actions in the past have

proved that impossible.If this situation was set many years ago in

the past, the flooding wouldve easily

decreased because of the amount of nature

at that time.

Sadly, this is the present and that means

that most of our nature is gone.

Past

Present

Our old natural dams are not there

anymore, thats why we have built

our own dams. Dams only control

the water flow, create energy, and

control where the water goes to. But

dams dont decrease water.

Reason 6:

-----------------------------------------------------------------------------------------------CAUSE FOR THE REASON: SUPPORTS

THE ECONOMY

THE SAVARNABHUMI AIRPORT IS BUILT ON A FLOOD PLAIN,

PREVENTING WATER TO GO THERE.


because it prevents the waterfrom going where it is supposed

to.

Of course, we want the airport to

be safe, because if it shuts down,

the economy drops massively.

Although Thailand is flooding,

tourists and businessmen are still

entering the flooded country.

If the airport closes, our

economy will be massively

effected because of the huge

loss.

Since the airport needs to stay

dry, this results to extreme-

protection.


9/10

Reason 7:

-----------------------------------------------------------------------------------------------CAUSE FOR THE REASON: TOO MUCH

WATER!

HUMANS HAVE PILED UP SANDBAGS TO PROTECT BORDERS OR

PREVENT WATER FROM FLOODING OUT OF BORDERS.

This is considered a reason because it is

preventing water to flood in a certain

area. This slows water down, but in the

end causes water to come rushing un-

intentionally.

This is done because of urgent need to

prevent an area from flooding.Eventually, the barrier breaks because of

the strong water pressure, and the

unstoppable amount.

This results to flooding other places.

Piling up sandbags does help certain

places very strongly such as Bangkok, but

mostly makes the situation even

worse.

This reason is basically the whole big

wrap-up thing to do to preventing

Thailand from flooding.

Yes, if we hadnt built all these barriers

and let the water naturally flow into

the gulf of Thailand and flood cities, itwouldnt have been this bad.


10/10

So, in conclusion, Why was Thailand flooding

in 2011?1. Increased amount of monsoons and precipitation/rainfall

2. Overflowing amount of water in Dams

3. Not enough/unavailable amount of drainage for the overflowingwater

4. Roads, Dams, Buildings, and bodies of water prevent the water fromnaturally flowing

5. Us humans have cut down most of our nature, not enough to soak upthe precipitated water, and we use dams instead.

6. The Savarnbhumi airport is built on a flood plain, preventing water togo there.

7. Humans have piled up sandbags to protect borders or prevent waterfrom flooding out of borders.

Thailand was flooded because of our actions, as well as thenatures actions.
