You can take 'know no bounds' in more ways than one....
I have posted on North American mega-water projects - mainly water from Canada on a number of occasions: NAWAPA, NARA, and the GRAND Canal or GCNA (see my 29 October 2012 post for a summary of the projects about which I have written).
I first heard of NAWAPA as a graduate student in the early 1970s when one of my professors mentioned it as a possible remedy to the Southwest's water shortage. The NAWAPA scheme also appeared in Marc Reisner's Cadillac Desert.
I have also posted on the China's Great South to North water transfer.
There are obviously other examples as well - Russia and India come to mind. My seeming disinterest in projects from other continents is unintended - I just have more access to North American readers and sources.
That's why I was intigued when a reader mentioned the Transaqua Project. I Googled it and found this brief June 2012 paper from Portia Tarumbwa-Strid, "The Transaqua Project: Beginning of an African Rebirth":
The project involves diverting flow from the Congo River to fill Lake Chad, use that water for irrigation and fishery restoration as well as inland navigation and hydroelectricity. Maybe lakefront lots, too.
She claims that 100,000 million cubic meters (100 cubic kilometers) per year can be diverted from the Congo River basin to fill Lake Chad. That is about 7.7% (she says 5%, but we're dealing with approximate figures here so the difference is not important) of the basin's annual discharge, which I assumed to be about 1,300 cubic kilometers, calculated from figures here).
I am unsure what she means by 'fill up Lake Chad'. The current area is about is about 1,350 square kilometers (mean depth = 1.5 meters) with a volume of about 2 cubic kilometers (using the mean depth). That is down from an area of about 25,000 square kilometers in 1963. To get the volume up to around 75 - 100 or so cubic kilometers, it would take a few years' flow of the diverted water to fill the basin, taking into account evaporation, which is quite high in the basin.
I love what Tarumbwa-Strid says about the Congo River's diverted water: it "...now flows unused [italics mine] into the Atlantic Ocean." Ah, yes - the same word, unused - my professors used (some said 'wasted') when they talked about diverting some of the Columbia River's flow to the Southwest. I am further reminded of Bob Hirsch's wonderful statement about the difference in the teaching of engineering hydrology from the 1970s to the present: "In the old days, we calculated how much water we could take from the river; these days, we calculate how much water must be left in the river." We would do well to remember that thought, whether in the Congo basin or Columbia basin.
By the way, I wonder if anyone has asked the four countries involved what they think of this plan.
Here is a later publication on the topic from EIR.
Here is another scheme to replenish Lake Chad.
It is good to remember that Lake Chad has naturally fluctuated in area and volume long before humans interfered - for the last 13,000 years or so. Here are two good items on that issue: Science Daily and this post. The latter post mentions that the Lake Chad Basin Commission approved a project to replenish Lake Chad. So who knows?
I found this video:
Now you know why I used the adjective 'goofy' in this post's title.
