Assam

The number of people affected by flooding in the state of Assam has increased dramatically over the last few days according to local authorities.

Background – 2017 Flooding

The first wave of flooding began soon after the onset of the monsoon rainfall in early June, affecting 60,000 people in 3 districts: Lakhimpur, Karimganj and Darrang.

By late June flooding had affected just under 100,000 people across 150 villages. Although flood waters had receded in some districts, areas of Karimganj were still under water in flooding that had continued for almost a month.

By 04 July, just under 15,000 people were displaced and staying in 112 relief camps set up in Karimganj district. Across the state as a whole, 6 districts and a total of 270,000 people were affected.

Rain in north east India and river catchments elsewhere has continued since then and the flood situation in Assam has deteriorated further.

Current Situation in Assam

In a report of 11 July, Assam State Disaster Management Authority (ASDMA) said that approximately 1.5 million people in 2,498 villages of 23 districts have been affected. The death toll has increased with some media outlets reporting as many as 44 deaths.

The worst-affected districts include Jorhat, Golaghat, Cachar, Dhemjai, Biswanath, Karimganj, Barpeta, Karbi Anglong, Sinotpur, Darrang, Hojai, Majuli, Lakhimpur, Kokrajhar and Nagaon.

As many as 276 houses have been completely destroyed in the flooding, with a further 1,376 damaged. As of 11 July there were 48,483 people are currently taking shelter in 115 relief camps opened up by the local administrations in 16 districts. A further 93 relief distribution points have also been set up. Over 4,000 of those displaced were in Lakhimpur; 5,500 in Kokrajhar and 5,600 in Golaghat.

Over 140,000 hectares of standing crops have been badly affected due to floods.

Central Team Visit

The Minister of State for Home Affairs, Shri Kiren Rijiju, led a Central Team to review the flood situation in the North-East, visiting the flood affected people in Assam and Arunachal Pradesh on 13 July, 2017.

Kaziranga National Park

In a report of 12 July from ACT Alliance, the global aid and relief alliance, said that the flood water has also caused widespread destruction in the world-famous Kaziranga National Park, where more than 560 animals, including 14 rhinos, were killed.

Damaged Roads and Rail Hinder Relief Operations

ACT said that infrastructure had also been badly affected, with road services damaged or interrupted at 2,847 places while railway tracks, damaged by landslides in the Lumding-Badarpur Railway division, were yet to be restored.

ACT are concerned that the damage to roads and other infrastructure could huinder the distribution of aid and relief supplies. ACT said:

“Since roads and bridges have been cut-off due to the rising of flood water at several places, transportation of relief materials to the flood affected villages would be the primary challenge for relief distribution. The situation may further be aggravated if rains continue in coming days and if there is an increase of flood water in the major rivers overflown. Therefore, it is also assumed that this may cause breaches of weak river embankments and cause damage to national and state highways in Assam and make access further challenging.”

Rivers and Rainfall

Rivers

ASDMA said that 10 rivers in the state were flowing above the danger mark, including the Brahmaputra and also smaller rivers and tributaries such as the Desang, Beki, Sankosh, Dikhow and Kushiyara.

The Brahmaputra was above danger levels at 5 stations in 5 different districts (Jorhat, Sontipur, Kamrup, Goalpara and Dhubri).

Rainfall

The most widely available figures in Assam are for the weather stations at Gauhati, Tezpur, North Lakhimpur and Dibrugarh Airport at Mohanbari, about 15 km north east of Dibrugarh City (Dibrugarh district), which sits on the banks of the Brahmaputra.
