I can't seem to get enough sleep any more, and I slept for a darned long time. Oh well.
Here's a pastime for you: the Ouvrages du Libron, where a canal crosses -- well, intersects -- a muddy, silty river with a tendency to flood, canal level being (on average) only slightly below river level. Solve it, without detour, locks or aqueducts. French engineers did, twice, and the present solution is well past its sesquicentennial and still going strong. Give up? Have a look!
