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.

It uses the kinetic energy of a stream to raise a small portion of water
well above the level of the stream.


John, you are wasting your time.
