Greetings, friends! Once again, more than 50 people have been killed due to the floods in Assam More than 45 lakh people are directly affected 95% of the Kaziranga National Park was inundated when the floods were at their peak Sounds familiar, doesn’t it?

Last some year data of floods

This is the story of last year The same situation repeated itself this year Things have gone from bad to worse More than 120 people have been killed in Assam floods this time And this is such a story… A frightening festival that keeps repeating itself every year Things are going from bad to worse In 2012, 124 people were killed due to floods in the north eastern states and Assam In 2015, 42 people (were killed) 28 people in 2016, 85 people in 2017, 12 people in 2018 Year after year people get killed This affects the lives of lakhs of people.

Lakhs of people are directly affected Several animals in National parks also get killed .

The first thing we need to understand is that Assam has always been India’s most flood prone state The most number of floods occur here The reason behind this is that the river Brahmaputra that flows through Assam is a very unstable one. It changes its direction frequently.

In fact, the researchers have discovered that a massive earthquake struck North-east India in the 1950s Ever since that earthquake, Brahmaputra has become even more unstable From 1950s to 2010, there have been around twelve major floods in Assam But you would notice that in the last few years, a major flood has occurred almost every year The frequency of the floods have increased so much So the question here is why has the frequency of the floods increased?

Why are more floods occurring? The reason behind this is DEFORESTATION on a massive scale, the cutting down of trees and forests Unplanned growth, the encroachment of floodplains and wetlands Floodplains are the nearby areas of a river’s course When there is an excess volume of water in the river, it flows out over the floodplains Builders and other people have started construction of houses on these floodplains.

They’ve started “Development” due to which the river water does not have enough room to flow As a result, water flows into people’s houses Another reason is the improper drainage system Climate change is another significant reason , so is improper construction of embankments. Here, I’d focus on two major areas-

i embankments and

ii climate change

The situation of floods right now is that Mizoram, Meghalaya, Tripura and parts of Bihar and Uttar Pradesh are affected A high alert has been sounded in Kerala because extremely heavy rainfall has been predicted in the next 3 days A flood like situation may also occur there This is a very interesting situation ,

Friends! Actually, the use of the word “Interesting” would not be apt. It is a very strange situation Because just a month earlier, there was scarcity of water in Kerala. There was a deficit of 46% in rainfall The level of water reservoirs were low and there was almost a situation of a water crisis And now, suddenly, extremely heavy rainfall has been predicted here.

So much so that floods may occur So, one month earlier, there was a water crisis. Now suddenly, so much rainfall that floods might occur This is a direct impact of climate change The number of days (on which) rainfall used to occur is diminishing due to climate change When it rains, it rains with more intensity.

The cases of extreme rainfall are on the rise due to which floods occur The total number of days of rainfall are falling due to which the situation of water crisis is also worsening The situation of drought is also increasing The same situation was before us in Mumbai a few days ago between June 20th and June 26th There was a 95% deficit of rainfall in Mumbai But when it rained, it was so extreme that all the roads were inundated and floods occurred in Mumbai too Looking at the situations of this year as well as last year from the perspective of the environment, then situations are going from bad to worse here as well The new EIA draft notification that.

I have explained about in this article will make the felling of forests easier, especially in the North East area and if more forests are cleared, the floods will become even more devastating and more people will get killed.

This is a clear cut reason Instead of taking positive actions, the government has taken negative ones Also, there was a controversy regarding the Dehing Patkai wildlife sanctuary in Assam that the government is wanting to do coal mining in that wildlife sanctuary It wants to clear even more forests- What will that lead to? The floods that occur will be more frequent Embankments, levee and dykes are three different names of the same thing.

They refer to the wall that is constructed on the bank of the rivers to control the flow of the river and direct it in a particular way and to prevent the flooding of the nearby areas Historically, all believe that this is a simple way to stop the rivers from flooding They can be made of concrete or even mud The problem that arises while building an embankment is that whenever you try to restrict a flow, and try to reduce its area, then the speed of the flow of the water will increase and its level will also increase.

So, the buildup of sedimentation in the embankment If it is not removed and maintained properly, the level of the river will continually rise and then water will start to flow over the embankments Then there’d be no use of embankments because the outside areas would be flooded the same as earlier Another thing is that the people who are living besides the embankments, who’ve constructed their houses here.

They are lulled into a false sense of security They feel that the constructed embankments will ensure that the river flows in the same area But what they do not know is that before the construction of the embankment , the river flowed over a larger area, its sedimentation used to be spread over a larger area due to which, there was obviously flooding before as a flood plain existed earlier.

Now that these houses have been constructed, the chances of them flooding will also increase When an embankment fails to stop the water, then it is called Embankment Breaching This can happen in two ways. First, when the river level rises so high that the water begins to overflow You can see how this happens in this article.

Second thing that can happen is that the embankment breaks A hole can arise in the midst somewhere. It could be weak at some point and the water starts to flow out of the hole If it so happens, then embankments would be of no use.

Therefore it is said that “An embankment is only as strong as its weakest point” because it needs to break from only one point and then the entire thing is laid to waste A break at point point could lead to floods everywhere Therefore they need to be constructed carefully, keeping high standards in mind If any “jugaads” (resourceful arrangements ) were made while construction, then the entire thing could break It needs more of regular maintenance In Assam,

there are around 450 embankments on the banks of rivers More than half of them are in extremely vulnerable condition. That is, they can break…They can break easily. Researchers believe that there is an ongoing administrator-contractor nexus in Assam Whenever, the floods occur, some people earn a lot of money.

The contractors that construct these embankments newly construct them after every flood and earn alot of money A report in The Hindu says that in the floods this year, more than 197 embankments have been damaged or breached which again shows that the embankments are not being repaired properly They are not being repaired timely and they are not being constructed in a proper manner In 2017,the Ministry of Highways decided to build a 1300 km long highway besides the Brahmaputra in Assam.

There’d also be an embankment along the highway to prevent flooding After 2017, there have been no updates to map its progress till now but a lot of people are against the construction of such a huge highway and such a huge embankment A lot of environmentalists also claim that construction of embankments lead to an increase in flooding .

the flow of the river would be stronger, they’d break with greater intensity due to which the nearby residents will face more floods and there’d be more destruction A study of 2018 stated that the Mississippi river in the US Due to embankments and “river engineering” there the chances of occurrence of floods have increased by 75% The floods that used to occur once in a 100 years now have an increased frequency of occurrence by 75% due to these embankments .

A question that arises here is – ” What is the solution? ” The solution lies hidden in Netherlands Netherlands is the world’s best country in case of flood control You can see the best proof of this in these two photos The first photo is of 1300s. The second one is of 2019 You can see how much land they’ve reclaimed from the sea in the past 700 years That is the lands that lay inundated previously, they have taken out the same from the water Doing this would mean,

obviously, that the chances of flooding in these areas is extremely high because actually, it used to be a sea earlier So, obviously, they undertook a lot of flood control measures They did massive things to achieve all this They have written down in their constitution that the Dutch people have a right to be protected from flooding .

You can imagine how seriously they must treat this to have it written even in their constitution They have very high standards regarding flood safety Whenever they adopt a new flood control measure then they do so while keeping in mind a huge and colossal flood that occurs once in 10,000 years Our country should be safe from that. None of our cities should get flooded from even that. For comparison,

the standard in USA is that of a 100 years to prevent floods in a 100 years In Netherlands, it is to prevent floods in 10,000 years They’ve done a lot of big and small things to achieve all of this Their technology is extremely good in case of flood prevention They’ve installed high tech sensors and constructed mighty infrastructure projects.

But I’d not like to talk about all of this I’d like to focus on a very small and basic thing of theirs In the past few years, Netherlands initiated a project called “Room For The River” Project They realized that its not always good to build huge machinery or infrastructure projects To focus on a river’s natural environment and observe its flow and then construct your infrastructure.

Accordingly Is much better and cheaper in the long run The simplest thing that they did was to relocate embankments further away from the rivers that is, they river was given a larger area to flow So whatever small changes occur in the flow of the river, it can spread over a larger area.

The problem of sedimentation also got reduced drastically So they constructed embankments further away and started to grow trees along the floodplain area inside The natural greenery and natural forestation further enhanced flood protection before the embankments So, in today’s times, the rivers in Netherlands look somewhat like this You can see a lot of green area near them and the embankments constructed are so far away from the rivers.

Another thing they did was to further lower the level of the flood plains this provided more height to the river to flow The river beds were dug up to further lower them so that the river gets more space to flow All the obstacles in the way of the river were removed.

special areas were created for water storage A reservoir was created where there’d be flooding If a flood occurs, all the water starts collecting there at one place So these are some simple steps that Netherlands adopted under its “Room For The River” Project I feel this would not be too difficult to implement in India.

I hope that while constructing such lengthy highways and embankments along it, it keeps such small things in consideration Rivers should be given a larger area to Free flow so that flood prevention becomes easier I hope that a day will come when so many floods cease to happen and we are able to save lives of so many people For the residents of Assam,
