Related to the study of fluids and how they move, especially when they interact with solid objects.
The hydromechanical system efficiently controls the flow of water in the dam.
Hydromechanical is formed from "hydro-" (from Greek "hydor", meaning water) and "mechanical" (from Greek "mechanikos", meaning relating to machines or mechanics). The word refers to the mechanics or behavior of fluids, particularly water, in motion or under pressure.
Think of 'water' ('hydro-') and 'machines' ('mechanical') working together — that's what hydromechanical means.
