Major Glacial Lake Surveys Underway in Arunachal Pradesh and Sikkim to Prevent GLOF

In a significant national initiative to mitigate the risks of Glacial Lake Outburst Floods (GLOF), the National Disaster Management Authority (NDMA) has launched an extensive survey of glacial lakes in the Eastern Himalayas. The survey focuses on Arunachal Pradesh and Sikkim, two crucial regions along the border with China, to map glacial lakes and assess the feasibility of early warning systems and other mitigation measures.

Expert teams are currently conducting a comprehensive survey and study of six high-risk glacial lakes located in the Tawang and Dibang Valley districts of Arunachal Pradesh. This state, which shares a 1,080 km-long border with China, has recently experienced significant infrastructure damage due to glacial lake outbursts. Notably, more than five bridges have been washed away by an outburst from Sangnga Nehgu Lake in Tawang district. This ongoing survey is the first of its kind in Arunachal Pradesh, aiming to address these critical issues.

Water supply disruption in ICR

A major water crisis is reportedly looming over Naharlagun and Nirjuli township areas as the Public Health Engineering and Water Supply department begins reconstructing the suspension bridge for the DI 300 mm water supply line over the Nyorch stream on August 23.

In an official communiqué, the executive engineer (EE) of the PHED & WS Naharlagun Division informed that the bridge partially collapsed on August 2, 2024, as villagers and other residents used it for commuting to their fields and for daily activities. The department further noted that the bridge reconstruction may take 15 days or longer, during which the drinking water supply would be affected.

Urban Flooding in Guwahati:

In recent days, Guwahati has experienced severe urban flooding, significantly impacting daily life and infrastructure. A brief but intense rainstorm led to widespread waterlogging across various parts of the city, exacerbating existing flood conditions.

In August, a sudden hour-long rainstorm inundated significant areas of Guwahati, transforming city roads into virtual rivers. Major areas affected include Chandmari, Maniram Dewan Road, Maligaon, Hatigaon, Beltola, Lachit Nagar, and GS Road. Low-lying regions such as Anil Nagar and Nabin Nagar, already prone to severe inundation, experienced heightened flooding.

The torrential rain caused severe waterlogging, leading to extensive traffic jams. Vehicles, including ambulances, were stranded for hours in many parts of the city, including Sixmile, Chandmari, and GS Road.

Floodwaters entered homes in several areas, damaging property and creating unhygienic conditions. Overflowing sewage further compounded the issue, affecting household cleanliness and safety.

Key infrastructure such as roads, drains, and bridges has been severely impacted. An hour of rain created a sea-like situation on city roads, highlighting issues with storm water management.

Chief Minister Himanta Biswa Sarma conducted field inspections in affected areas. The Chief Minister directed the Guwahati Metropolitan Development Authority (GMDA) to expedite drainage improvements and mandated the construction of a guard wall to prevent future inundation.

The rapid onset of flooding and the resulting disruption of normal life have led to significant public dissatisfaction, with many residents expressing frustration over the city's flood management measures through social media.

The Central Water Commission reported that the Brahmaputra River, while flowing above the danger mark, is showing a falling trend in Guwahati. However, the flooding has highlighted the urgent need for improved urban planning and infrastructure to better manage heavy rainfall and prevent future flooding.

The recent flooding in Guwahati underscores the critical need for enhanced urban flood management strategies. Immediate repairs and long-term infrastructure improvements are essential to mitigate the impact of future rainstorms and safeguard the city’s residents.

Meghalaya Water Floods Guwahati, Assam Minister Blames Neighboring State

Assam Minister Ashok Singhal has attributed the severe flooding in Guwahati to water from neighboring Meghalaya, citing the red hue of the floodwater as evidence. The city experienced unprecedented rainfall on August 5, with 136 mm of rain recorded in just one and a half hours, overwhelming the drainage system.

Singhal stated, “This is not Guwahati’s water; it is Meghalaya’s water. Guwahati’s water is black, Meghalaya’s is red!” He pointed out that the red color of the floodwater is due to the red soil from Meghalaya.
