Head (geology) - Wikipedia

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. In an aquifer, it can be calculated from the depth to water in a … See more In fluid dynamics, head is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid. From Bernoulli's principle, the total energy at a given point in a fluid is the energy associated … See more After free falling through a height $${\displaystyle h}$$ in a vacuum from an initial velocity of 0, a mass will have reached a speed The term See more The distribution of hydraulic head through an aquifer determines where groundwater will flow.

In hydrology, the head is the point on a watercourse up to which it has been artificially broadened and/or raised by an impoundment. Above the head of the reservoir natural conditions prevail; below it the water level above the riverbed has been raised by the impoundment and its flow rate reduced, unless and until banks, barrages, weir sluices or dams are overcome (overtopped), whereby … WebEach contour, or equipotential, represents a line of equal hydraulic head.
