Hydraulic head — is a specific measurement of water pressure or total energy per unit weight above a geodetic datum. It is usually measured as a water surface elevation, expressed in units of length, but represents the energy at the entrance (or bottom) of a… … Wikipedia
Hydraulic fracturing — is a method used to create fractures that extend from a borehole into rock formations, which are typically maintained by a proppant. The method is informally called fracing or hydrofrac. The technique is used to increase or restore the rate which … Wikipedia
Hydraulic tomography — (HT) is a sequential cross hole hydraulic test followed by inversion of all the data to map the spatial distribution of aquifer hydraulic properties. Specifically, HT involves installation of multiple wells in an aquifer, which are partitioned… … Wikipedia
Hydraulic jump — A hydraulic jump is a phenomenon in the science of hydraulics which is frequently observed in open channel flow such as rivers and spillways. When liquid at high velocity discharges into a zone of lower velocity, a rather abrupt rise (a step or… … Wikipedia
Depth–slope product — The depth–slope product is used to calculate the shear stress at the bed of an open channel containing fluid that is undergoing steady, uniform flow. It is widely used in river engineering, stream restoration, sedimentology, and fluvial… … Wikipedia
Hydraulic fracturing — Fracturing of rock at depth with fluid pressure. Hydraulic fracturing at depth may be accomplished by pumping water into a well at very high pressures. Under natural conditions, vapor pressure may rise high enough to cause fracturing in a… … Energy terms
