A borehole is drilled to the specific elevation where pressure measurement is required, typically below the expected zone of saturation. A piezometer is a scientific instrument designed to measure fluid pressure within a confined system, most commonly groundwater or soil saturation.
Piezometer Definition Hydraulic Head Calculation Method
By plotting hydraulic head over time and depth, professionals can generate contour maps of pressure and identify flow directions within the subsurface. Regular checks involve comparing the instrument readings with manual water level measurements to confirm that the system is functioning correctly and that the data stream remains uninterrupted.
In the field of geotechnical engineering and hydrology, this device serves as the primary tool for quantifying pore water pressure, which is essential for assessing slope stability, foundation settlement, and the overall behavior of earth structures. Engineers analyze the data in relation to the elevation of the sensor to calculate the hydraulic head, which represents the total energy at a specific point.
