“hyporheic zone”的概念、定义、翻译、参考文献-科学参考

hyporheic zone

Biology

The region beneath and alongside the bed of a stream or river where the stream water and groundwater mix. Water can flow through the hyporheic zone as a consequence of upwelling of groundwater or seepage of stream water, giving rise to hyporheic (or interstitial) flow. This zone sees continual interchange of material between stream water and groundwater, which can impact on the quality of both, for example in terms of water chemistry and pollutant load. It is also important as a habitat, especially for microbial and invertebrate communities, and for fish spawning.

Geography

A spatially and temporally dynamic mixing zone at the interface between groundwater and surface water. Hydrologic exchange between streams and hyporheic zones is important in keeping surface water in close contact with chemically reactive mineral coatings and microbial colonies in the subsurface. For an exhaustive treatment of the topic, see Harvey and Wagner in J. Jones and P. Mulholland, eds (2000).
