Hyporheic zone

This article may be too technical for most readers to understand. Please help improve this article to make it understandable to non-experts, without removing the technical details. The talk page may contain suggestions. (September 2010)

The hyporheic zone is a region beneath and alongside a stream bed, where there is mixing of shallow groundwater and surface water. The flow dynamics and behavior in this zone (termed hyporheic flow or underflow) is recognized to be important for surface water/groundwater interactions, as well as fish spawning, among other processes.

The assemblage of organisms which inhabits this zone are called hyporheos.

The term hyporheic was originally coined by Traian Orghidan^[1] in 1959 by combining two Greek words: hypo (below) and rheos (flow).
