downcurrent
Descending water movement
Downcurrent describes movement in the direction a current flows—downstream in water, or with the prevailing flow in air or electrical systems.
As a noun, a downcurrent is a current moving downward, especially in water or atmosphere: The downcurrent pulled debris toward the ocean floor.
The opposite is upcurrent.
