Or if they got dragged down under by a swimming mount or dodged a strike or a bolt that knocked them into the moat

mounts wont path into the moat though, because there is only wall on the other side, which they cannot path through

At its weakest you'll get 1zlvl above ground level, an extensional +1 wall layer on ground level and a ditch, usually around 5zlvls wide with paved floor where possible to ensure clear shots.
Oh and ditches do also give a protection to raised bridges that walls cannot provide.
They all fit together rather nicely.

this design maximizes offensive power, but does not work with my fort design because i need as much as level 1 as possible for above-ground farming (im too lazy to pump up water and make hydroponic towers). I also tend to relay only on marksdwarves as military, so the smaller towers that cover wall-huggers serve other important purposes as well, like cleaning up resurrected undead that refuse to move, goblins outside of the main bunker's range that refuse to move, and give me more map control in general.
