  "term": "Piezometric surface",
  "field": "Meteorology and atmospheric science",
  "definition": "An imaginary surface representing the level to which water would rise in a series of piezometers installed in a confined aquifer. It indicates the potentiometric surface of the groundwater, showing the hydraulic head across a region. The slope of the piezometric surface determines the direction of groundwater flow, which is perpendicular to the contour lines of equal head.",
