Morphology
The noun phrase 'keel arch' is directly compositional: 'keel' describes the shape or profile being applied to 'arch', so the meaning of an arch shaped like a ship's keel (S-shaped curve) follows from the constituent meanings. A B1 learner who knows both words can infer the distinctive keel-like form, making the expression transparently derivable from its parts.
Etymology
The noun keel arch comes from the word keel, the curved bottom of a 'ship', because the two sides of the arch sweep into an S-shape that looks like a ship's bottom. So, the name now means a pointed S-shaped arch used in buildings.
