But would there
have been ditches WITHOUT such bridges in the first place? How did
you get the water out of the ditch and onto the field without the
bridge/pump system?

Of course there would have been. Watering can be moved out of the ditch
by hand very easily using a simple syphon method and that is common enough
even today. See pic on this cite:

only if you turn the whole world on its head. Siphoning from a lower to a
higher point sounds like a perpetual motion machine. Are you trolling?
