What perplexes me is that these earthen structures have not fallen into invisibility through erosion and become mere depressions that are hardly recognizable as man-made.

The other factor is being able to run a line of levels this far across terrain and get the right slope to encourage adequate flow without over flowing.

There was so much freight traffic from the port of Rome (Ostia) back and forth that there is a partially confirmed theory that they had a canal, running paralell to the Tiber so that they could run traffic one way on each.

Saw a terrific show on TV about the Port of Ostia that has been rediscovered using sattelite imagery.
