What is a piezometer commonly used to measure?

A piezometer is a specialized instrument used primarily to measure the pressure of groundwater. It is designed to provide data on the hydraulic head and groundwater levels within an aquifer or groundwater system. The pressure measurements taken by a piezometer are critical for understanding groundwater flow dynamics and can be used in various applications such as hydrogeological studies and environmental monitoring.

The pressure of groundwater is significant because it affects the movement of water through aquifers, informs the design of well systems, and helps determine the suitability of a site for various uses, including environmental assessments and water resource management. In combination with other data, piezometer readings can assist in understanding both the quantity and quality of groundwater available.

While flow rates, water quality, and soil contamination are important aspects of water resource management, they are not the primary functions of a piezometer. Instead, those measurements would typically involve other tools and techniques, emphasizing the specialized role of the piezometer in groundwater pressure measurement.
