It looks more to me like that is a bridge used to support a big pump
for some kind of irrigation. Note the pump in the middle with the
overhead to rise the pump.
I suspect that the "bridge" served to hold a "hydralic ram" which uses
the velocity of the water to pump a small portion of the water to the
level of the surrounding fields.
Nope. Hydraulic rams need a head of water above the pump so that the
water drops into the ram. - its the action of the water falling into the
ram that makes the pumping happen.
Nope, yourself.
You just don't understand how a hydralic ram operates.
I do but I'd love to see a cite that would prove me wrong. I have a use for
such a beast.
It uses the kinetic energy of a stream to raise a small portion of water
well above the level of the stream.
A stream can certainly be used to do that with a hydraulic ram but the
stream must allow the water to drop into the ram not just flow past it
gently like the water does in a slow moving irrigation channel.
I'd certainly be very interested to see a pic of any hydraulic ram that
works as you say it will. I can't see how a slow moving stream can make
use of the water hammer effect that gives the 'ram' its name but I'd
certainly like to know more details. Can you post a cite please.
