_ The volume of water passing a given point per unit of time.
The active flow of water within a stream, river, or creek. May also be used in terms of lowflow, baseflow, etc.
The discharge in a natural channel. Although the term "discharge" can be applied to a flow of a canal, the word "streamflow" is used only to describe the discharge in a surface-stream course. The term "streamflow" is more general than "runoff", since streamflow may be applied to discharge whether or not it is affected by diversion or regulation.
The discharge of water from a stream.
water flowing through permanent channels.
The rate at which water passes a given point in a stream, usually expressed in cubic feet per second (cfs).
The rate of water flow (volume/unit time) passing a given cross section of a stream. Some common units include: cubic feet per second, cfs, ft3/s cubic meters per second, m3/s gallons per minute, gpm
The total discharge of water within a watercourse, including runoff, diversions, wastewater effluents, and other sources.
The discharge that occurs in a natural channel.
Discharge that occurs in a natural channel. A more general term than runoff, streamflow may be applied to discharge whether or not it is affected by diversion or regulation.
The water flowing in a stream channel.
Streamflow, or channel runoff, is the flow of water in streams, rivers, and other channels, and is a major element of the water cycle. It is one component of the runoff of water from the land to waterbodies, the other component being surface runoff. Water flowing in channels comes from surface runoff from adjacent hillslopes, from groundwater flow out of the ground, and from water discharged from pipes.
