Is there a formula for calculating the pressure drop in drainage channels?

Drainage channels are non-pressure self-priming pipes; there is no pressure in them to begin with, so where could there be a pressure drop?
Reply to 2# tqg317: Even if flow occurs naturally due to the terrain, there must still be head loss; otherwise the loss would be too great and the desired flow rate wouldn’t be achieved
