What is hydraulic head?
Q: What is hydraulic head?
A: Hydraulic head is a specific measurement of water pressure or total energy per unit weight above a datum.
Q: How is hydraulic head usually measured?
A: Hydraulic head is usually measured as a water surface elevation, expressed in units of length.
Q: What does hydraulic head represent in a piezometer?
A: Hydraulic head represents the energy at the entrance (or bottom) of a piezometer.
Q: What is a piezometric well?
A: A piezometric well is a specialized water well used to measure hydraulic head in an aquifer.
Q: How can hydraulic head be calculated in an aquifer?
A: In an aquifer, hydraulic head can be calculated from the depth to water in a piezometric well, and information of the piezometer's elevation and screen depth.
Q: What is the screen depth of a piezometric well?
A: The screen depth of a piezometric well is the depth at which water can enter the well from the surrounding aquifer.
Q: How is hydraulic head expressed?
A: Hydraulic head is expressed in units of length, typically in feet or meters.
