Morphology
The meaning is directly built from 'alluvial' (river- or water-borne sediment) modifying 'flat' (a level expanse), so a learner who knows both words can infer a flat area composed of alluvial deposits. Although somewhat technical, the adjective+noun composition is literal and cross-linguistically regular, making the overall sense predictable.
Etymology
Alluvial flat brings to mind a river that slows and drops mud and sand, with alluvial pointing to those river layers and flat showing the wide, level land they make. That's why an alluvial flat is a flat area made by river deposits and is often very good for farming but can flood easily.
