Someone posted before, anyways these are just people guessing what remains

omg... the CCTV footage cut off after the mud hit ... knew it was going to be very bad.....

An informative description of quite likely what actually happened...

500 lives paid for this knowledge:
1. The region is earthquake prone. You cannot even build a dam because it will be destabilised by earthquake.
2. The only solution is: GTFO. Nobody should live in the riverbed region. Everyone needs to live much higher up along the slopes (Nepal needs to do this. The border crossing at the riverbed, maybe delete it).
3. Seismic/ground movement sensor monitoring in Tibet (China can do this).

From AI:

Why a “giant dam” is a poor primary fix​

This was a high-speed ice–rock debris flow (~50 m/s over ~20 km), not a clean water flood. A large dam here would face:

• Very steep, narrow gorges and high seismicity
• Rapid siltation from glacial debris (the reservoir would fill with mud and rock)
• A dam-break flood worse than the original pulse
• Construction and access above ~2,000–4,000 m on an international border
• No control over the next glacier collapse above the dam

There is no dam or hydropower plants along that section of river along the china border? All the hydropower plants are in the nepal side.

I already answered this: no dams built in the high Tibet mountains because of the earthquake danger. See above.

‘Initial Warning Lapses: Reports indicated that Nepal's early warning system was ill-equipped and the initial alert was sent 16 minutes after the flash floods began on August 26, 2026.’

Where's your sources? I already included mine.
Here's another one:

Flood Journey: Timeline from 8:37 PM Earthquake to Devghat

The report lists the flood flow and the timeline of the floods:

• 8:37 a.m.: Seismological measurement measuring 4.4 on the Richter scale (Department of Mines and Geology).
• 8:50 am: Data collection from Bhotekoshi Syaphrubesi hydrological station stopped (last water level at 8:40 m, Warning level: 6 m, Danger Level: 7 m).
• 9:00 am: Officials at the District Administration Office, Rasuwa and Betrawati Water Measurement Centre received information that a big flood had entered the Bhotekoshi River from the Tibet side.
• 9:15 am – 9:16 am: First phase of alert and 6.79 lakh SMS sent to Trishuli coastal area (up to Muglin) for high alert.
• 9:20 am: Betrawati hydrometry station closed (final water level at 9:20 m3.55; warning level: 4.1 m, danger level: 5 m).
• 10:28 am: SMS was sent again to the Prithvi Highway, Muglin-Narayangadh road section and the settlements along the Trishuli coast to be alert as the floods reached around Dhading-Galchhi.
• 11:26 am: The water level at the Furke Khola (Malekhu) water measurement station crosses the alert level.
• 11:43 am: The water level at the Furke (Malekhu) centre has crossed the danger level and the Furke River has been washed away by the flood along with the water measurement station bridge.
• 11:50 am: Flood reaches Malekhu Bazaar.
• 13:00 pm: Floods cross Muglin.
• 13:35 p.m.: The lake has not yet been fully reopened and the risk remains.
• 14:14 pm: The water level at Kalikhola hydrometer station has breached the danger level (12.1 meters) and reached the highest level of 12.3 meters.
• 15:20 pm: Flood reaches Narayani-Devghat area.
• 16:00 pm: The water level at Devghat hydrometer station has started receding at the highest point of 6.57 meters.
• 18:30 pm: The flow at Devghat returns to normal (about 4 meters).

‘Initial Warning Lapses: Reports indicated that Nepal's early warning system was ill-equipped and the initial alert was sent 16 minutes after the flash floods began on August 26, 2026.’

I think the anecdotes are clear: people treated the flood warning as a slow rise in water. Not as a high-speed tall tsunami of mud and rocks. That's why the warnings were not treated seriously.

looking at the pics of the border station, might have chance of survivors. Looks like there is some building buried beneath that slit and mud.

Buildings are not designed to withstand such lateral forces from one side one. But the lower levels might have pockets of survivors, since the flow is not all liquid, and the mud may dam up preventing further flooding inside.

START DIGGING.

it's just names, with some date of birth. at least now we know if it's someone we know...

Those are personal data u know

 

[tauntme]

Imagine if this happened at night

 

[Oxygenatedwater]

Those are personal data u know

personal data for most of us but precious information for people's missing family members

Names and gender are enough. I dun see the need for excessive information like DOB and/or passport no to be posted. These extra information doesn’t help much but pose personal data exposure risk.

 

[Rellit]

Some of you guys here are downright vile, using a natural disaster to push a certain agenda

In such emergencies, I think the need for such data for identification supersedes whatever data or privacy protection. What for care about data protection when the person cannot even be found or dead.

There can be multiple people with the same names. Especially if the name is common enough.

Dats why name and gender identifier is good enough.

besides surely at least one of the family member know their family went to nepal. Unless he is all alone in this world.

such full information need not be revealed to whole world (we don’t even know them, so what purpose?!)

and lastly u see other countries with similar disasters also dun share full details

that is their way of doing things.. if you think it's excessive you can feedback to them

In disaster response, you don't have time to finetune your strategy like in corporate. Think we need to step out how we see things are done in corporate setting. Privacy concern, PDPA all that stuff is for peacetime. The focus here is not on privacy, it's putting out sufficient identifiers such that any rescuers, disaster response, public, anyone at all, can have details to refer to when they come across a body, a bag, belongings, passport washed ashore or uncovered by some random stranger etc.

They need all the help they can get. There is no call centre or call agent to go walk the caller through 1 by 1.

Nvm dun argue with u no point lol

like i say these full information published this way is of no use at all

You guys are weird.
* There is no PDPA in Nepal
* They rank amongst the poorest countries in the world, don't expect 1st world standards
* They have a lot more critical and urgent things than to get concern over a name list
* Why are you imposing your values over them?
