Effects of heavy metals and hyporheic exchange on microbial community structure and functions in hyporheic zone

Journal of Environmental Management, 2022
The responses of microbial communities in hyporheic zone to the eco-hydrological process have been a hotspot in river ecological health research. However, the impact of different metal pollution levels and hyporheic exchange on the microbial communities are still unclear.

Residence time of bedform-driven hyporheic exchange

Advances in Water Resources, 2008
Biogeochemical and ecological transformations in hyporheic zones are dependent on the timing of hyporheic exchange. We show through linked modeling of open channel turbulent flow, groundwater flow, and solute transport that the residence time distributions of solutes advected by hyporheic flow induced by current–bedform interaction follow power-laws ...

Bedform-induced hyporheic exchange with unsteady flows

Advances in Water Resources, 2007
The interaction between surface and subsurface water has a crucial influence on the biochemistry of stream environments. Even though the river discharge and the flow conditions can seldom be considered to be steady, the influence of this unsteadiness on the hyporheic exchange has often been neglected.

Hyporheic Exchange Due to Cobbles on Sandy Beds

Water Resources Research, 2022
AbstractHyporheic exchange induced by riverbed topography and roughness provides important ecosystem functions. We investigated how cobble clusters embedded in a finer‐grained sand bed affect the near‐bed channel flow and the exchange of surface and subsurface water.

Hyporheic Exchange in a Meandering Pool‐Riffle Stream

Water Resources Research, 2022
AbstractInteractions among stream characteristics, hyporheic exchange (HE), and groundwater flow are a crucial control for physicochemical and biological reactions in hyporheic zone (HZ). Many previous studies solely investigated the HE induced by pool‐riffle bedforms or meanders but few research studied the interactions between them despite this pair ...

How Does Subsurface Characterization Affect Simulations of Hyporheic Exchange?

Groundwater, 2012
We investigated the role of increasingly well‐constrained geologic structures in the subsurface (i.e., subsurface architecture) in predicting streambed flux and hyporheic residence time distribution (RTD) for a headwater stream. Five subsurface realizations with increasingly resolved lithological boundaries were simulated in which ...
