Morphology

silting = silt (transparent) = silt + ing

The noun is a direct verbal noun formed from 'silt' + '-ing', and the meaning is fully recoverable from the base verb.

Etymology

Silting comes from silt, a word for very fine 'soil' carried by water. Think of a river slowly being filled by this fine soil; that's why silting means the build-up that makes rivers or lakes shallower and can block water flow.
