manmade waterscapes?

Question

what are the machines needed to create a manmade waterfall?, do they use pumps? or what ?, please answer architecturally based

Answer 1

Edited:
I highly recommend PondMaster Pumps...they are magnetic drive, use no oil, rarely if ever need any more than having the impeller replaced. ( very easy to replace) If you plan on having a pool w/fish below the falls this is something to consider. No oil leaks to contaminate.
External pumps

To answer architecturally would take too long. Open the link and see a complete set of design photos and how to.

You will need:
pond liner
Flex tubing or PVC pipe
Filter fall
Pumps/internal or external
If a large pond and fall
Skimmer
Seaming tape/splice for larger liner
A multitude of misc items
Do the research before you do the digging

Answer 2

It would depend on the size of your waterfeature. Factors to consider are the height of the water, the 'rise' the volume of water, usually measured in liters or gallons per hour and the 'look' you are trying to achieve. By 'Machines' I gather you mean pumps, which will take the water to the required location and either force it over a 'fall' or up to a reservoir. There are several types of pump, simply those that 'push' water up and those that suck it up. Add to that pumps which decrease volume of water flowing while increasing pressure, and vice versa.
Really you should 1st consider what it is you are trying to build, that will give you some base figures. Such as height, distance and volume of water. From there you can add in weight, which will be a factor in the strength of the waterfeature supporting structure. Once you have those numbers you can determine which pumps are suitable for your 'feature' You can easily check specs online.
