Uttarkashi's Dharali In Mountain Of Debris As High As 3-Storey Building: How Will It Be Cleared?
The Indian Army, with the IAF, SDRF, NDRF, ITBP, BRO, and administration, continues to lead rescue and relief efforts in flood- and landslide-affected region of Dharali and Harsil
Three days after a massive flash flood hit Uttarakhand's Uttarkashi, the Dharali village near Gangotri is now buried in debris and sludge.
The Indian Army, in close coordination with the Indian Air Force (IAF), SDRF, NDRF, ITBP, BRO, and civil administration, continues to lead large-scale rescue and relief efforts in the flood- and landslide-affected region of Dharali and Harsil.
357 rescued so far: What is the status of Dharali?
Dharali remains completely cut off due to widespread landslides. However, road clearance efforts have progressed up to Limchigad, where the launch of a Bailey Bridge is currently underway and expected to be completed by Friday evening.
In terms of weather conditions, Matli and Harsil have experienced a period of clear skies, aiding rescue efforts. However, low visibility and rain over Dehradun have temporarily delayed some planned air sorties. 'So far, a total of 357 civilians have been rescued, with 119 airlifted to Dehradun. Rescue teams on the ground include Indian Army columns, combat engineers, medical units, and specialised Search and Rescue (SAR) dog squads. The NDRF has deployed 105 personnel, working in tandem with SDRF and ITBP teams, including medical officers stationed in Harsil and Dharali," said the Indian Army in a statement.
Army doctors, nursing assistants and combat medics are providing on-site treatment to rescued civilians at transit locations. Among the evacuees are 13 Army personnel, while eight soldiers from the 14 Rajputana Rifles remain unaccounted for.
The civil administration has reported that approximately 100 civilians are still missing, and two civilian fatalities have been confirmed.
How does the clearing of debris work?
The debris clearance process in Uttarkashi after major floods or landslides is a multi-step, multi-agency operation with significant technical and logistical challenges due to rough terrain, ongoing weather hazards, and the volume of material.
The main steps are:
Assessment and immediate response: Authorities activate disaster response protocols as soon as an incident is reported. Multi-agency rescue teams (Army, National Disaster Response Force—NDRF, State Disaster Response Force—SDRF, local administration) are deployed for immediate search and rescue, supported by helicopters if access is blocked.
Damage and safety survey: Technical committees are formed, often including district officials, geologists, engineers from the Public Works Department (PWD), irrigation and forest departments, disaster management authorities, and mountaineering experts. They conduct field surveys to assess the danger from unstable slopes, identify safe routes, mark hazardous structures, and recommend if further evacuations are needed.
Search and rescue operations: Sniffer dogs, drones, and manual teams search for trapped or missing people. Locations where people were last seen are prioritized for focused clearance. Residents sometimes assist in identifying likely sites of entrapment.
Deployment of heavy machinery: Once safety is assured, advanced earthmoving equipment such as JCBs and excavators is brought in to remove large boulders, thick layers of mud, and collapsed structures. Road clearance is prioritized to restore critical connectivity. Blocked highways and damaged bridges are cleared or replaced with temporary structures (like Bailey bridges) to reconnect cut-off regions.
Monitoring and ongoing risk assessment: The situation is monitored using aerial surveys and drones, especially looking for newly formed lakes, fresh landslide risk, or further rising water which could trigger secondary disasters. The central disaster management authorities may order continuous assessment, especially in fragile eco-sensitive zones.
Sustained relief and rehabilitation: Debris and mud clearance continues in phases, usually starting with accessible and high-priority zones (like highways, hospitals, and main habitation clusters), then progressing to secondary sites.
What are the challenges?
The main challenges faced during debris clearing in Uttarkashi are:
Sheer volume and depth of debris
Rugged and remote terrain
Damaged or destroyed infrastructure
Ongoing and unpredictable weather hazards
Limited accessibility for relief equipment
Fragile ecosystem and safety risks
Search for survivors among debris
Disrupted communication and power
What next? Helicopter sorties, Bailey bridge and more
On August 7 alone, 68 helicopter sorties were conducted, including six by the Indian Air Force, seven by the Army, and 55 by civil helicopters. A heli-bridging network has been activated between Dehradun, Harsil, Matli, and Dharasu ALG, supported by C-295 aircraft to ferry critical supplies, rescue teams, and stranded civilians.
To aid coordination, the Indian Army has established a Communication Control Room at Harsil, with satellite and Wi-Fi connectivity operational. Meanwhile, BSNL and Airtel are working to restore public mobile networks in the affected region.
Senior military leadership, including the General Officer Commanding, Uttar Bharat Area, and the Commander, 9 (Independent) Mountain Brigade, are on the ground in Harsil to oversee operations and ensure synergy between military and civilian agencies.

The statement said, 'The planned actions for August 8, 2025, include the launch of a Bailey Bridge at Limchigad to restore vital road connectivity, the aerial induction of critical relief materials and equipment, continued search operations in Harsil and nearby areas, and the evacuation of remaining stranded civilians by air from Harsil to Matli and Dehradun."

Confirmed: Dharali mudslide destroys 70% of buildings in hardest-hit area
At least 128 buildings in the mudslide-affected parts of the tourist village of Dharali in Uttarakhand's Uttarkashi district have been either completely buried or swept away, India Today can confirm after analysing three sets of satellite data. The assessment is based on high-resolution optical satellite imagery provided by US-based Maxar Technologies and ISRO. Credit: Maxar Technologies An independent visual analysis of post-disaster satellite imagery by India Today's Open-Source Intelligence (OSINT) team established that the roofs of only 54 out of the roughly 182 buildings were still intact as of Friday, August analysis covers only parts of Dharali village where the mudslide settled in a fan-shaped pattern – between the foothills of Dharali mountains and the Bhagirathi river. Credit: Maxar Technologies The analysis of satellite imagery, combined with photos and videos recorded by Indian Army troops who reached the site immediately after the impact, establishes that the mudslide descended on the village in more than one wave. Many multi-storey buildings were buried under debris by subsequent waves of the mudslide. Source: Maxar Technologies, Indian Army At least four medium-to-large buildings — two of them popular hotels — were buried under several feet of debris in the later waves. These buildings can be seen in photos published by the Indian Army on August 5, but are absent in satellite imagery captured two days later. Caption: Satellite image captured two days after the tragedy shows debris settled over a large part of Dharali market, through which National Highway-34 to Gangotri passes. Inset images have been taken from a video provided by the Indian Army Images also show that the Bhagirathi river's flow was altered after the sheer volume and force of mud and rocks surged into it from the Kheer Gad OF UNCERTAINTYAuthorities and experts have been struggling to ascertain the exact extent of damage, largely due to the unavailability of clear satellite images because of prevailing cloud cover over the village and surrounding debris is spread over an area of 20 hectares, according to an ISRO assessment. The height of the debris column is estimated to be between 25 and 50 feet. Red rectangles represent buildings that have been completely oblitirated by the mudslide.

Three theories have been floated regarding the cause of the RESCUEThough a multi-agency rescue operation is underway in Dharali, specialised teams armed with cutting-edge equipment and heavy machinery needed to locate and rescue survivors trapped under the debris have struggled to reach the site due to road breaches and the collapse of a key bridge on National Highway-34, which connects Uttarkashi town to Dharali. The Indian Army has deployed Chinook helicopters to transport power generators and earthmovers to the affected least 100 people, including nine Army personnel, are missing. More than 500 locals and visitors have been people have been confirmed dead, as per official figures.- EndsMust Watch
