Manmade waterscapes?
Answers: Edited:
I highly recommend PondMaster Pumps...they are compelling drive, use no oil, seldom if ever need any more than have the impeller replaced. ( very effortless to replace) If you plan on having a pool w/fish below the falls this is something to consider. No grease leaks to contaminate.

Do the research before you do the digging
It would depend on the size of your waterfeature. Factors to consider are the echelon of the water, the 'rise' the volume of hose, usually measured in liters or gallons per hour and the 'look' you are trying to complete. By 'Machines' I gather you be a sign of pumps, which will take the river 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' hose down up and those that suck it up. Add to that pumps which decrease volume of marine 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 underside figures. Such as distance from the ground, distance and volume of water. From near you can add within weight, which will be a factor contained by the strength of the waterfeature supporting structure. Once you have those numbers you can determine which pumps are suitable for your 'feature' You can efficiently check specs online.
