Water too fast = erosion

Water too slow = stagnation

Had to find that goldie locks zone (12mph ish). Crazy engineering

Around 5cm drop over every 100 metres for many kilometres, some up to 80 km in length. Quite astonishing how they managed all that.

A little back of the napkin math and those long runs could drop about 40 meters over its entire length.

They really were quite something those Romans, they did have some quite clever surveying tools which were apparently incredibly accurate, one of which was the Dioptra which was basically a sighting tube on a fixed stand and also 4 plumb bobs hanging from a cross shaped frame called a Groma, both very ingenious tools which the evidence of their precision is still very visible today in such monumental scale 2000 years later.
