But what about a semi-circle? A shape that will not fall through the shape of the hole...
ummm, if you turn it with the flat edge verticle, it will fit through a lot of places in the hole.

You really do need a constant diameter shape or you can line up the maximum diameter of the hole with the minimum diameter of the cover and drop it in. Of course, you could use a large lip, but that is wasteful.

There are many answers.
Shape to not fall in: this is an OK answer, but really, all they need to do is put flanges or a rim on the inside of the hole and any shape would be fine.
Shape for "rolling": this is a better answer, but then again, the cover must be transported to its destination. Regardless of the form of transport, it has to be removed and put on the ground. To remove it from the vehicle is going to require either: a person lifting it (all the problems associated with moving it into place) or a mechanical system to unload it, which could then reasonably be designed to unload it directly into place.
Maximum area for entry/exit: I kind of like this one, since it is undeniable and applies to the hole itself as well.
