Hyporheic
From Wikipedia, the free encyclopedia
Hyporheic flow is the multidimensional percolating-flow mixing of shallow groundwater and surface flow. Hyporheic flow spreads over the permeable region under and beside an open stream bed, circulates inside the interstitial space around the wetted perimeter of the bed, and recharges (or discharges) into the groundwater zone.
The mechanism of hyporheic flow can be triggered by stream water percolation, or the groundwater upwelling seepage beneath the stream bed and alongside the stream banks.
