Morphology

floodway = flood + way (transparent) = flood + way

The meaning is a literal compound 'flood' + 'way' meaning a path or channel for floodwater, which is directly inferable from the components.

Etymology

Floodway is a simple compound of flood ('a large flow of water') and way ('a path'). It literally means a path or channel that guides extra water away from towns and buildings, which is why a floodway is used to carry floodwater safely around populated places.
