When there's no water in the Mekong for elec in PP...

This is a part of our Cambodia forums to chat about anything Cambodia-related. This discussion forum is at the top of our site because it's usually the busiest part of the expat community chatter with random topics on just about everything, including expat life, Khmer politics, Cambodian blogs we have or have come across, or whatever else our members want to discuss. Whether you're an expatriate, tourist, Cambodian or random traveler just passing through South East Asia, you are welcome to talk about anything or start new topics yourselves.

The warming climate will affect rainfall in different places differently.
In the hot-house climate here, where weather is intensified anyway, those extreme weather events will probably be exaggerated in both directions.
And yes, it is new territory.

Dams magnify that, and just in themselves they are the biggest factor immediately. easily.

I am no expert on the situation, but it seems it could be the point of no return, unless the other countries on the Mekong un-dam too.

Ummm
Maybe the dams?
Maybe "increased severe weather events including drought"?

Why does NObody listen to the scientists?
They know exactly WTF is going on and have been talking about it for years.

But glad to hear it has attracted a little curiosity now that everybody's 24hr aircon is threatened.

(and you wonder why Greta and all the other bright bright kids are steaming angry)
I probably wasnt clear. we know its dams and drought. I meant their seems to be no coordination between the dams themselves or any organization that keeps track of what the dams are doing. so probably no one knows exactly how its going to effect electricity and water supplies. it certainly looks like it will be a lot worse then last year tho

I think I've found a solution, now I just need a nerd!

Apparently you can link a deep cell battery to a UPS, which would give me a chance to daisy chain a couple of deep cells if I needed.

That should give me the power to survive any shut-off.

Is there a nerd in the house?

Dams could make it better if managed properly. They could let the dam levels drop gradually during the dry season, so the rivers keep flowing, then ensure the dams are full at the end of the wet season. Instead of keeping the dams full during the dry season, then letting the water go when it rains, causing floods.

PS Ira, I was not saying that global warming is causing the present low water levels.
I was making a parallel, about people suddenly waking up to a situation when it is already too late.
Scientists has been warning about exactly this Mekong/dams scenario for a number of years now.
...and some people, who totally ignored them before, are now saying "oh, i think we might have a small problem after all"

Water flow from China’s Jinghong dam to decrease

Vientiane, Lao PDR, 6 August 2019 –– The outflow of water from the Jinghong hydropower station in China’s Yunnan province will decrease by about 25-45 percent over five days, according to an official notification from China’s Ministry of Water Resources being copied to the Mekong River Commission Secretariat on Monday.
In the notification, the Ministry said the amount of water from the Jinghong dam will start decreasing from 1,100 cubic meters per second (m3/s) to about 600-800m3/s from August 11 – 15 before it will be gradually returned to the original level.
The decrease is made for the “maintenance for the transmission lines of the power grid,” the notification said. The Jinghong dam lies on the upper part of the Mekong River, where it is known as the Lancang in China.

Severe to extreme drought is expected to hit countries in the lower Mekong basin from now until January 2020, warns the Mekong River Commission. Thailand and Cambodia would be hardest hit compared to Lao PDR and Viet Nam.
