VHGs are commonly cited in groundwater-surface water exchange literature and mapped spatially and temporally to indicate where groundwater is entering and leaving a surface water body bed. Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum. It is usually measured as a liquid surface elevation, expressed in units of length, at the entrance (or bottom) of a piezometer.
