The flow or discharge of rivers, i.e., the volume of water passing a location per unit of time, is commonly expressed in units of cubic feet per second or cubic metres per second.
Cusec is a unit of flow rate,[2] used mostly in the United States in the context of water flow, particularly of rivers and canals.
