Rivers and streams whose interaction with groundwater depends on the fluctuating position of the water table, ranging from effluent streams in the wet season to influent streams in the dry season.
Interacting Stream
Conditions range spatially or seasonally between discharge from the river into the groundwater system and discharge from the groundwater system into the river; not to be confused with an ephemeral river.
Because of the periodic dependency of these streams on groundwater, management of groundwater abstraction may be important.
