Morphology
The meaning 'agitated, choppy water' is directly and transparently derived from combining 'rough' (uneven, harsh) with 'water' (sea/expanse of water); it is a straightforward adjective + noun composition. This pattern is common cross-linguistically and follows normal English semantics, so a B1 learner who knows both words can predict the MWE's meaning.
Etymology
Rough water comes from the clear image of the sea struck by strong wind and waves, where the water is choppy and the rough surface makes boats rock. So, rough water means 'water that is choppy or hard to sail'.
