The Northeastern state of Assam is hit with floods every year around this time and life comes to a standstill. Floods are often accompanied by landslides that add to the loss of life but also damages public infrastructure such as roads, ಌbridges, and railway tracks.
Earlier this year, large tracts of land was swept away by flood in Assam, which led to railway tracks precariously hanging in the air at places in Assam, visu🌃als of which surface♑d on social media.
Experts have pointed out that floods in the two river basins of Brahmaputra and Barak have occurred since yore but the unprecedented destruction witnessed in the recent years can be primarily attributed to faulty flood control measures, population pressure, shrin💜kage of water-bodies, unregulated construction and skewed development strategies.
Environmental scientist Dr Partha Jyoti Das told PTI that the devastating floods in May and June have taken larger swathes under its grip this time, when compared to the last few years, and the toll registered in the e🀅arly-monsoon deluge has not been this high in the recent memory.
He said, "Growing population and construction in flood-prone areas are some of the reasons behind the burgeoning damage in the state. In several places, breach of embankments has caused widespread de💧struction. Add to that, frequent flash floods leave people with little time to protect life and property."
Das added that flood predictions and🌞 early warnings do not reach the vulnerable population on occasions, thus giving th🅠em no scope for preparatios.
He further said, "Drainage congestion in low-lying areas, which is a result of rapidly changing land use practices, fast pace of urbanisation a⛎nd expansion of human habitat all around, at the co🧸st of natural waterways, have also intensified the flood situation."
The current wave of floods 𓆏has claimed 174 lives, besides damaging crops across 2,35,845.74 hectares and leaving 90 lakh people in the lurch, according to a spokesperson of the Assam State Disaster Management Authority (ASDMA).
An official of the Water Resources Department noted that the Brahmaputra basin is among the most flood-prone areas in the world, followed closely by the Barak, and with nearly 100 tributaries and sub-tributaries feeding them, the two rivers m✤a🔜ke 40 per cent of Assam vulnerable to deluge.
A series of factors, both natural and anthropogenic, add to the woes, h♈e said.
The official added, "Highly potent monsoons, seismic activities leading to a change in the course of the river and rise in the river bed, and the unique geꦇo-environmental setting of the rivers, particularly the Brahmaputra basin in the Eastern Himalayas, are some of the reasons why the flood situation keeps deteriorating in Assam."
Urban fl💞ooding in places such as Silchar, Guwahati, Dibrugarh, Barpeta, Nalbari a🌸nd Tinsukia have also laid bare the faults in the drainage system of the state.
River specialist Pradip Pujari told PTI that drainage congestion and choking of local water bodies, which had earlier served as an outlet for fl▨ood waters, are largely responsible for urban flooding.
Echoing him, Assam University’s former professor o🔯f environmental science Dr Abhik Gupta said hill-cutting and deforestation, along with climate change, compound flood problems. He added that a combination of strategies is 🍃being discussed by authorities to find a permanent solution.
He maintained that water resources engine🦩ers have always advocated the construction of large storage reservoirs but this is fraught with risk, considering the geo-ecological fragility of the region.
"Non-structural measures like issuance of flood warnings can play an important role in reducing damages. Use of geo-synthetics for fortifying embankment𒈔s is also being considered as an option," he said.
Das, however, asserted that people might still have to put up with floods, at least to a certain extent, despite the adoption 🔯of all possible measures to minimise the scourge, as "technological fওixes have certain limitations against natural processes".
He added, "Reducing vulnerability and enhancing resilienceಌ while taking into account the impact of 🥂climate change should be at the core of flood management along with the exploration for a feasible technological solution."
