a waterfall

[Anonymous]

I was thinking of waterfall with a trestle bridge going over it,but I don't want the water to wash away the soil. Can you give me some pointers on what I should do. Thanks[8D]

Any water feature you include in your garden railway will undoubtedly be built using traditional water feature techniques, which necessitate a liner of some kind, which would inherently prevent any earth from being eroded away by the flowing water. Lots has been written on water feature construction both in the pages of GR and countless gardening magazines and books, so that's the first place I'd look for pointers.

In effect, it's the same thing that Dave's photo shows--a permanent base onto which the bridge is built.

I'm building one this spring, I have bought a 'pond kit' which contains liner, pump, waterfall etc. I intend to pipe water to a stone trough in my rockery, if the supplied waterfall in the kit is not good enough I will build one utilising part of the liner and a few small troughs. I think it is better to have a series of gentle falls rather than a Niagra and this helps to keep the flow under control and by having some troughs on the way down it helps to keep some water out of the main pond when it's all switched off, which would otherwise, perhaps, overflow. I will probably bridge the water course in one but it would be an easy matter to build a pier off of a rock placed in the water course. This is all assuming of course that I don't lean on the spade, which breaks, then fall onto the garden fork and become perforated!![:D]

Kim,
Don't forget a very adequate overflow from your pond! My pond is 6.7m wide X 12.13m in length, giving some 81.27 sq. m of surface area (train runs around at water's edge on 3 sides) and is some .9m deep. I have an overflow pipe installed that has a 3 inch inside diameter, and it is not enough! 4 or 5 times a year I have the pond overflowing it's banks in a heavy rainstorm!

This summer I'm gonna have to figure out some means of providing more overflow capacity.

Thanks for that Bob, I piped a drain into the bottom corner of the back garden last year with an outlet pointing straight at were the pond will be. Because I have a flat garden I intend to have the water level of the pond a few inches above the garden level to give me a fall into the drain, which has a diameter of a couple of inches. I can see I'm going to get some overflow as well! That's some size pond Bob, mine will only be 6' x 4' ish and my first step into the world of ponds.
Cheers,
Kim

I have a leak some where in my pond lining, so my "over flow" is just to leave the pump on all night, the pond will be about 3/4th empty.

Instead of just going over the waterfall, take a look at going under as well. Currently the tracks go through a tunnel under the falls. Eventually there will be a "tourist line" that will travel up over the falls on a timber trestle bridge.

Tom, how did you do that? Have a video that opens automatically? Even my old computer and dial-up service let it show right away!! And it's a treat for the eye...thank you for posting it!

Sandy;

That is a "GIF" file (a type of graphics file) formed by 10 single photographs. Each frames shows for about 1/12 of a second, giving the illusion of video. Not a video, just a "fast" slide show from stills.
