Catskill_Aqueduct

[Micky]

The 163-mile (262 km) aqueduct consists of 55 miles (89 km) of cut and cover aqueduct, over 28 miles (45 km) of grade tunnel, 35 miles (56 km) of pressure tunnel, six miles (10 km) of steel siphon, and 39 miles (63 km) of conduit. The 67 shafts sunk for various purposes vary in depth from 174 to 1,187 feet (362 m).[3] Water flows by gravity through the aqueduct at a rate of about 4 feet per second (1.2 m/s).[4]

In this context, what is a cut and cover aqueduct?

A grade tunnel?

A pressure tunnel?

A steel siphon?

Conduit.

Just what it sounds like. Dig a trench, build your aqueduct, and back fill it.

Come on, Micky.

I'm not one to pile on, but don't you know how to use Google?

Why would you spend time reading stuff on the web and then not take the next logical step and DAGS the terms that you don't understand?

In fact, "cut and cover" is actually a *link* on the page you were reading that will take you to the definition. Why would you forgo that link and instead ask us to tell you something that you could have found with one click?
