An instrument which measures pressure head or hydraulic pressures in a conduit or hydraulic pressures within the fill of an earth dam or the abutment; at the foundation because of seepage or soil compression; or on a flow surface of a spillway, gate, or valve Piezometers are used regularly for monitoring of all four dams at Horsetooth Reservoir
An instrument for measuring pressure head in a conduit, tank, soil, etc It usually consists of a small pipe or tube tapped into the side of the container, the inside end being flush with, and normal to, the water face of the container, connected with a manometer pressure gage, mercury of water column, or other device for indicating pressure head
A nonpumping well, generally of small diameter, for measuring the elevation of a water table
A well with a screen length that is only 1-5% of an aquifer's saturated thickness Generally used to measure the total potential or head at a point in an aquifer
A well with a short, slotted screen (1 to 5 feet) for measuring a potentiometric surface or elevation of the water table
