base flowRate of discharge in a stream where only the throughflow and groundwater flow from subsurface aquifers contribute to the overall flow.
|
2 |
base flowGround water that enters a stream channel, maintaining stream flow at times when it is not raining.
|
3 |
base flowThat part of the stream discharge that is not attributable to direct runoff from precipitation or melting snow; it is usually sustained by groundwater.
|
4 |
base flowa stream or river's normal flow volume.
|
5 |
base flowSustained 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.
|
6 |
base flowthat portion of river discharge derived from groundwater flow.
|
7 |
base flowsustained flow of a stream in the absence of direct runoff. It includes natural and human-induced streamflows. Natural base flow is sustained largely by groundwater discharges.
|
8 |
base flowSustained flow of a stream in the absence of direct runoff. It includes natural and human-induced streamflows. Natural base flow is sustained largely by ground-water discharges.
|
9 |
base flowThe typical flow rate for a given stream at a particular time of year.
|
10 |
base flowSustained, low flow in a stream; ground-water discharge is the source of base flow in most places.
|
11 |
base flowthe groundwater contribution to a stream[10]
