I have seen two version for determining the height to use for calculating the earth force on a retaining wall.
Version 1: Only the height above the horizontal foot of the fall is used (i've seen this version somewhat more frequently)
Version 2: the depth of the horizontal foot of the wall is included in the height calculation (First time I saw this was in one of Elif Bayram's practice test. After looking it up I found some more examples that did that.
Is there a correct version? I guess I am trying to figure out if there is an NCARB-correct version.
