Origin

Sound + meaning
六书liùshū
形声xíngshēng

Most characters — around four in five — are built this way: one part hints at the meaning, the other at the pronunciation.

This origin belongs to the traditional form 溝; 沟 is its simplified writing.

Same sound today

The traditional form 溝 pairs 氵 (water) with 冓 for the sound; the simplified 沟 is a later shorthand, so its right side is not the historical part.
