Groundwater
Unit weight: The assumed density of water for porewater-related calculations
Wall base porewater pressure based on:
- Averaged
- Back of wall
- Front of wall
If a front-of-wall static groundwater elevation is defined
and different from the back-of-wall static groundwater elevation, the
porewater pressure acting on the base of the wall will be assumed based
on either the conditions at the back (heel) of the wall, front (toe) of
the wall, or averaged from both cases, depending on the selection.
The assumed value of porewater pressure is assumed to act
uniformly along the base of the wall. Note that this simplifies the
effect of seepage on the actual porewater pressure distribution at the
base of the structure.
