Barrage

Barrage is a term with several related meanings. In civil engineering and hydraulics, a barrage is a barrier constructed across a river or estuary to regulate water flow and water levels upstream. The term derives from French barrage, meaning barrier or dam.

In practice, a barrage typically consists of a series of gates or sluices that can be opened or closed to control discharge, permit navigation, and stabilize upstream water levels. Unlike a fixed dam that stores large amounts of water, a barrage often aims to maintain a specific upstream level, regulate flood risk, and modulate tides or river flow. Some barrages incorporate sluice structures and, in some cases, turbines to generate electricity while maintaining flow control. Barrages are common along rivers and estuaries in various regions where water management and navigation are priorities.

The term barrage also denotes a heavy, sustained artillery bombardment intended to saturate a target area, suppress enemy fire, or anchor an attack. Barrages involve coordination across multiple firing units and can vary in duration and intensity, from short, intense barrages to prolonged artillery barrages.

In everyday language, "barrage" can describe a rapid sequence of questions, criticisms, or other remarks directed at a person, organization, or topic. The word is used across different contexts to convey a high-volume, concentrated flow of force, questions, or information.
