Hyporheic flow patterns regulate physical and chemical conditions in the HZ, determining microbial activity and occurrence of hyporheic fauna too (Franken et al.
In particular, dams simplify alluvial system structure, reducing surface water peak flows and hyporheic flow and thus preventing refilling of alluvial aquifers (Berman and Pole, 2000).
Alteration of flow, regardless of source, can in turn influence temperatures of floodplain soil through its influence on patterns of hyporheic flow
and associated advective heat-exchange (Gerecht et al.
Three-dimensional vertical flow and lateral hyporheic flow
in and around structures are monitored using an arrav of small air-water and oil-water manometers.
