Water that seeps into a stream through a permeable rock or sediment unit that outcrops in the bottom or banks of the stream.
Related Topics: [ structures] Minimum, long-persistence flow in streams produced mainly by seepage; sometimes called subsurface flow.
That part of the stream discharge that is not attributable to direct runoff from precipitation or melting snow; it is usually sustained by groundwater.
the portion of stream flow that is not due to runoff from precipitation, usually supported by water seepage from natural storage areas such as aquifers, lakes, or wetlands.
Wastewater flow (including a reasonable amount of inflow and infiltration) originating from residential, commercial and industrial sources.
(or "dry season flow") - precipitation that percolates through the ground and reaches streams slowly over a long period of time and that produces a steady flow even during dry periods
The portion of stream flow that is supported by groundwater seepage into a channel, rather than by stormwater runoff.
Springs; stream flow coming from subterranean sources in contrast to surface runoff.
the portion of a streams flow contributed by ground water, seepage, or water moving over the land
The amount of water in a stream that results from ground water discharge.
streamflow coming from ground-water seepage into a stream.
The volume of flow in a stream or river during dry conditions (as opposed to conditions influenced by storm runoff).
The flow in a stream between storm events. This flow is supplied by groundwater.
the part of stream flow that is attributable to long-term discharge of groundwater to the stream. This part of stream flow is not attributable to short-term surface runoff, precipitation, or snow melt events.
The portion of river surface flow which remains after deduction of storm flow and/or purchased imported water.
The water flowing in a stream which is fed by ground water. During dry periods it is only the base flow which passes through the stream channel.
The portion of stream flow that is not runoff and results from seepage of water from the ground into a channel slowly over time. The primary source of running water in a stream during dry weather.
River surface flow, not counting storm flow and/or purchased imported water.
Sustained or fair-weather runoff--generally that portion of the streamflow derived from discharging ground water or other delayed sources such as lakes or snow fields.
flow coming from ground water or spring contributions, which may be considered as the normal day-to-day flow.
Water that, having infiltrated the soil surface, percolates to the ground water table and moves laterally to reappear as surface runoff.
The flow in a channel due to soil moisture or ground water.
The sustained portion of stream discharge that is drawn from natural storage sources, and not effected by human activity or regulation.
the water that flows in a river during the dry periods between rainstorms. The San Antonio River had historic base flows fed by artesian springs, but because the Edwards Aquifer has been drawn down by urban well water use, the San Antonio River currently has no natural base flow water source. Today's base flow is provided primarily recycled water that is pumped into the river in Brackenridge Park near the Witte Museum.
(3) the portion of stream discharge derived from such natural storage sources as ground water, large lakes and swamps, but not derived from direct runoff or flow from stream regulation, water diversion, or other human activities.
Streamflow originating entirely from ground water discharging to the stream.
Stream discharge derived from groundwater sources as differentiated from surface runoff.
flow of a river or stream when it is composed entirely of groundwater from springs.
That proportion of water flowing in a stream which is due to ground-water seepage into the stream channel. Forest Management
The flow contribution to a creek by groundwater. During dry periods, base flow constitutes the majority of stream flow.
Rate of discharge in a stream where only the throughflow and groundwater flow from subsurface aquifers contribute to the overall flow.
The natural recharge of groundwater to a water body
The typically expected, sustained low flow of a water body.
In mathematics, the base flow of a random dynamical system is the dynamical system defined on the "noise" probability space that describes how to "fast forward" or "rewind" the noise when one wishes to change the time at which one "starts" the random dynamical system.
