Subject field(s)
  • Fluid Mechanics and Hydraulics (Physics)
  • Dams and Causeways
DEF

The upward pressure against the base of an impervious dam, transmitted by water in the foundation from the water behind the dam, or pressure on the upper surface of any horizontal joint or crack in a dam. Such pressure tends to offset the weight of the dam and in some cases to overturn it; it reduces the dam's stability or resistance to overturning.

DEF

Pressure in an upward direction against the bottom of a structure, as a dam, a road slab, or a basement floor.
