A large earth canal is to be lined. Could you share your experience with me?

0.96 cubic metres of water for every metre of the canals length.\n\nor 8.24 square metres of surface covered for every metre of length.

there is ground water... be ready to be fascinated...

This article appears as though it may, but you have to pay:\nhttp://www.ingentaconnect.com/content/geol/jgs/1987/00000144/00000001/14410059

how much depth you have to work with. Will things like sewers, TV cable, fiber optics, electrical lines, gas lines be in the way? Also, what is the geology of the ground you're going to tunnel through.

Check out the link and start with that....use concrete underground or if chain make sure it goes deep enough to where they can't dig under.  I also like the idea of making the fences electric....very high voltage, this way they can't cut it (alot of ranchers on the border are having this problem right now...illegals cutting their fences, if it's electric they can't cut it)\nAnd it's NOT racist to want to secure your borders.

The link woould indicate that the fillet would depend on the mismatch between roadbed height and adjacent land (which can become eroded).  Good luck.

The closest I came to any kind of a real answer was that there was a surveyor by that name who lived in Czarist Russia in 1830 and planned a series of canals to make a river run backward.\n\nhere's the site:  \n\nhttp://www.time.com/time/archive/preview/0,10987,950711,00.html

Well, I appreciate the fact that you include a waiver for many of the things that would make this task impossible, that helps a lot ;)\n\nIf some explorer were able to dig a hole straight through the center of the earth, the digger would slowly find the apparent effects of gravity decreasing as he or she approaches the center.  On the surface of the earth we feel a good, solid 1G because we have this huge mass effectively "underneath" us but our explorer would slowly be working his way down until only a portion of said mass is "underneath" them... the rest is above them and around them.  By the time they reach the center, they would essentially have a nearly equal amount of mass in all directions, all pulling with pretty much the same amount of force.  Yup, they'd feel like they were floating and would have trouble discerning any "up" or "down" by then.  When they start digging the rest of the way through, they are no longer digging "down", and the further from the center of the earth it will feel more like digging up.  By the time they break through to the other side, they're back to a nice steady 1G.\n\nI hope this helps you, and I hope you don't need the equasions.  We're talking about some serious calculus here and I'm not sure I'm up to that right now ;)\n\nDuckie

Braided fishing line would work...get as heavy as you can.

that is a really big project, hope this helps, good luck

The water must be given as initial push to go uphill. Once the flow is established, siphoning can occur.

I don't think so.  A signal having to fight through a mile of earth would get deflected/weakened unless you had relay nodes already burried.  Without those, communication would be spotty at best even with high grade equipment.

find a mountain, hill, or other land area that is elevated, that collects water.\n\nDig a trench, or path, so the extra water flows through it.\n\nMake sure the path you dig goes into another body of water, like a pond, lake, or other water area.

This should help you a lot.\n\nhttp://home.earthlink.net/~drbobshields/DO.html
