The researchers are searching at a few other reasons
behind the surprising floods inside the northeastern districts of Bangladesh
together with Sylhet, Sunamganj and Kurigram.
Those districts were hit by the 0.33 spherical of
floods this year.
Residents of Sunamganj say that they have not faced
this sort of extreme flood in lots of years. In overall, more than three.five
million humans were trapped by water, government say.
• Why can't floods be averted in spite of flood
manage dams?
• Tens of millions of humans in horrible situations
in Sylhet Sunamganj due to floods
In the meantime, the street communique among
Sunamganj and the rest of the u . s . has been stopped. Rail verbal exchange
with Netrakona has been severed.
Other than this, at the least 17 different districts
of the u . s . a ., including Rangpur, Kurigram, Nilphamari, are feared to be
laid low with floods, authorities said.
River researchers say that heavy rains in India's
Assam and Meghalaya are a major issue behind such sudden floods this year, but
some different elements have worked outdoor of it.
Heavy rains in Meghalaya:
Cherrapunji region of India receives the highest
rainfall in the world.
Water vapor from the Bay of Bengal hits the
mountains of Meghalaya and rises. It started raining heavily there.
Flood warning center authentic Arifuzzaman Bhuiyan
said that 972 mm of rain has been recorded in Cherrapunji, India inside the
last 24 hours. due to the heavy rains, this year's horrible floods have befell.
AKM Saiful Islam, Director of Water and Flood management
Institute of Bangladesh college of Engineering, instructed BBC Bangla that the
rainfall in Cherrapunji inside the final three days became 2487 mm and it is
nonetheless raining. Such non-stop rain has happened once in 1995, 2798 mm in 3
days and 2760 mm in 1974. little or no has been seen, says Mr. Islam
Cherrapunji area of
Meghalaya, India begins from the border of Sunamganj district. As a
result, the water from there comes without delay to the river of Bangladesh.
Bhairav or Meghna flows into the ocean.
But river researchers experience that there is lots
of difference among the context of the past rainfall and the modern condition
of the rivers.
Professor Saiful Islam believes that the heavy
rainfall in Cherrapunji is the main purpose in the back of this sudden flood.
“Global warming has modified the climate-climate or
rainfall styles. Now whilst it rains, it rains much deeper. there may be
additionally a los angeles Niño within the Pacific. that also played a function
within the heavy rains.
'When it rains in Cherrapunji, it reaches Tahirpur
within six to 8 hours. however the water cannot come down fast sufficient. As a
end result, it spreads round and creates floods,'' he says.
He fears that if it rains for two or 3 greater days
in Cherrapunji, the flood may additionally exceed all information.
Heavy rains have additionally brought on floods and
landslides in India's Assam. In Assam, Barak and Kushiara rivers are flowing
above the hazard line. Floods have came about in lots of regions along with Guwahati.
it's miles recognized that 35 human beings have died to this point in Assam and
Meghalaya.
Indian media reviews that as a minimum 1.1 million
people were tormented by the floods in Assam.
Lack of water wearing ability of the river:
The excess rainwater from Meghalaya or Assam flows
out of the Haor thru Meghna or Yamuna to the Bay of Bengal.
However the researchers say that the principle
motive at the back of this flood is that the excess water coming from the
upstream cannot come out.
And for this they blame the lower in navigability of
the river.
River researcher Muminul Haque Sarkar tells BBC
Bangla that every year silt and stones come down with water from upstream. It
came and filled the river mattress in Bangladesh. The water sporting ability of
the river decreases. Then when there's greater water in this river, it
overflows and floods the surrounding place.
Researchers are blaming unplanned stone quarrying in
the Indian component for the destruction of the river's navigability.
Professor AKM Saiful Islam says, especially inside
the upstream of India, because of stone extraction, the soil loosens and flows
into the river. As a end result, the river bed is filled. there is a
navigability crisis. bushes are also being cut there.
In addition to this, those researchers are blaming
the rivers for no longer dredging nicely, the river mattress being full of
rubbish, the wetlands being filled because of houses or urbanization.
for that reason, researchers believe that only while
there may be greater rain in Meghalaya or Assam, flooding takes place in Sylhet
or Kurigram area.
Unplanned improvement:
Professor Islam says that behind this surprising
flood there are many motives created by way of human beings themselves.
As a result, the flood water now takes time to
recede. in advance, because there had been swamps and sinkholes, flood water
may want to stay in lots of places. however now that isn't occurring.''
"We've got roaded pockets in special places in
Howar. As a end result, the water drift is obstructed. because of the
development of houses in city areas, water does now not get a risk to visit the
ground. As a result, we are experiencing more intensity of flood. due to these
reasons there are early floods and very intense floods," says Professor
Islam.
Etna, Mithamin avenue is accountable?
over the past
days in Bangladesh, many human beings had been blaming the
Etna-Mithamain avenue for the repeated floods in the Sylhet location through
social media.
Prof. Islam additionally says that obstruction of
water glide due to unplanned production of roads is one of the reasons of
floods.
however how is itna-mitham through social media?
Professor Islam isn't always willing responsible
this flood on the road.
This avenue is likewise crafted from north to south.
As a end result, it may be developing some obstruction to the flow of water
within the Haor, however it isn't the only purpose of flooding."
River researcher Mominul Haque Sarkar says,
"The roads that have been constructed in Haor within the east-west path
are developing the primary impediment within the movement of Haor's
water." Many such roads had been built with none planning."
Professor Saifur Islam says that the roads or
improvement sports which can be taking area in Howar have no longer been
planned. it's miles because of this that the floods have become so intense.
Bangladesh high Minister Sheikh Hasina at the
District Commissioners' conference in January final ordered that expanded or
flyover roads ought to be made in Howrah any further.
but handiest in Haor area of Sunamganj district,
most of the roads being constructed are nevertheless 'all season' or
'submersible' roads.
No longer having a dam :
specialists say that most of the townships in
Sylhet, Sunamganj, Kishoreganj or Netrakona Haor regions do no longer have town
safety dams. As a end result, if the water in the river or river starts
offevolved to rise for a few motive, it speedy enters the town or residential
region.
Director of Flood control Institute AKM Saiful Islam
says, "town safety dams have no longer been constructed in those regions
in Howar. If that isn't achieved, houses will need to be built better, shelters
will must be built. That was now not completed either. As a end result, when
surprising floods arise like this, the harm is greater.
Sponge cities are being built in many countries such
as China. If there's a flood in those towns, the water is stored within the
town and an environment is being created to use it.
However these professionals say that it's miles very
hard to save you the flood in this type of situation because the flood has
damaged the file of rain or water increase in Bangladesh this time.
