For Thousands of Years, Egypt Controlled the Nile. A New Dam Threatens That

Tue Feb 11, 2020 1:43 am

The first of the water wars has officially arrived. To say this is a major crisis for Egypt is an understatement.

Does the blue nile flow more water than the white? Egypt better not piss off Sudan or Uganda...

The population growth in Egypt is one of the main problems, growing by 2m people a year it is not sustainable in their enviroment. In five years time they will probably be at war over water. Population growth in other parts of the world is also a problem, the planet can only sustain so many human beings, perhaps a global pandemic would be welcome.

I haven't read that whole article yet, but just started scrolling and read that Egypt topped 100M people????

That's absolutely crazy.

And using it for all sewage is just flat out irresponsible. Runaway population growth, lack of basic sanitation controls.

Yet I'm told my plastic straws are destroying the planet. Perspective.

Turkey partly "switched off" fresh water supply to Syria, Iraq, Jordan .. some time ago by way of building a range of dams.
this is beyond others one reason for the armed conflicts in the area.

I can't read the article,
but here is the dam,

https://www.google.com/maps/@11.2171658 ... a=!3m1!1e3

Very close to the Sudan border.

The blue Nile carries 2/3 of the the water and silt.
https://www.livescience.com/57023-nile-river-facts.html

And here is an article discussing what is going on between Egypt, Sudan, and Ethiopia.
https://thearabweekly.com/egypt-treadin ... n-dam-deal


The amount of water the Blue Nile carries and especially the silt is concerning to Egypt and Sudan. They depend on the water and silt.

Egypt gets 97% of it's water from the Nile.

I think Egypt needs to invest more in desalination, but at the end of the day, they are a large country that is very dependent on one body of water.

A few million civilian casualties of war will most likely occur.

The silt does not go beyond the Aswan Dam i.e. it has been filling up the Lake Nasser for quite some time now.

Well eventually with flood controls they can release more SILT, but with more dams, it becomes more of an issue.
Still , there is an even bigger catastrophe at hand for the delta.

http://www.globalconstructionreview.com ... le-del7ta/

The low-lying delta plain is only about 1m above present sea level. The northern third of the delta is lowering at the rate of about 4-to-8mm per year due to compaction of strata underlying the plain, seismic motion, and the lack of sufficient new sediment to re-nourish the delta margin being eroded by Mediterranean coastal currents.

While the coastal delta margin is being lowered, sea level is also rising at a rate of about 3mm per year. Delta lowering and sea-level rise thus accounts for submergence of about 1cm per year.

At present rates, saline intrusion is now reaching agricultural terrains in central delta sectors, and the scientists say parts of delta surface will be underwater by the year 2100.

The major downside of the Aswan Dam. This is a long standing issue.

I wonder if there is some way to release the collected silt or just dredging it as fertilizer.

The new dam in that respect does not change all that much.

Hi scbriml, yes, had a really good time here and ready to move on to the next great adventure, one shouldn't be too gready.

Time for Egypt to begin the Qattara Depression Project! :spin:

But people always seem to over think the project, thinking tunnels or trenches need to be dug or god forbid there was a proposal to use nuclear bomb to blow a path for the water to get there. None of that is necessary. Just pipe it, you can do it above ground, over mountains if you want, and connect them to a power plant to have the thing make some thing useful in the beginning, as it runs. Yes it will take years for enough water to be moved to start creating a lake and even longer to actually impact weather. But it will at some point. Which will change everything for Egypt.

Agree with everything you said, I am surprised they have not already started on QDP, but damming the Nile will certainly accelerate that effort. Egypt's population growth is already straining their existing resources so some creative thinking will be needed in the future to address Egypt's water concerns.

For starters Egypt is putting limits on some of the most water-intensive crops like rice.

Well, actually, it's a bit the other way around. The lifeboat can take only so many people, until it water rushes overboard and sinks it. You are already onboard. Your choices are to let the boat sink (by doing nothing), volunteering yourself off -- to make some space, limit the number of incoming passengers, or (somehow) increase the boat size.
