Pressure head is a component of hydraulic head, in which it is combined with elevation head. When considering dynamic (flowing) systems, there is a third term needed: velocity head. Thus, the three terms of velocity head, elevation head, and pressure head appear in the head equation derived from the Bernoulli equation for incompressible fluids:
Generally the head losses (potential differences) at each node are neglected, and a solution is sought for the steady-state flows on the network, taking into account the pipe specifications (lengths and diameters), pipe friction properties and known flow rates or head losses. The steady-state flows on the network must satisfy two conditions:
The current HYDRUS (2D/3D) suite of software and their predecessors have a long history. The origin of these models can be traced back to the early work of Dr. Shlomo Neuman and collaborators (e.g., Neuman, 1972 [10]) who developed their UNSAT model at the Hydraulic Engineering Laboratory of Technion – Israel Institute of Technology, in Haifa, Israel, long before the introduction of personal ...

The total hydraulic head of a fluid is composed of pressure head and elevation head. [1] [2] The pressure head is the equivalent gauge pressure of a column of water at the base of the piezometer, and the elevation head is the relative potential energy in terms of an elevation. The head equation, a simplified form of the Bernoulli principle for ...

The volumetric discharge through the stream-bed can be calculated if the difference in hydraulic head is known: = where is the volumetric discharge through the stream-bed ([L 3 T −1]; m 3 s −1 or ft 3 day −1) is the hydraulic head of the river (elevation stage)
