A piezometer is a device used to measure groundwater pressure and water levels in soil and rock. Think of it as a specialized water-level measuring tool that helps surveyors and engineers understand what's happening with water underground. It's similar to how a thermometer measures temperature, but instead, it measures water pressure and levels beneath the surface. This information is crucial for construction projects, environmental monitoring, and ensuring the safety of structures like dams and buildings.
