| ACCLIVITY |
, the slope or steepness of a line or plane inclined to the horizon, taken upwards; in contradistinction to declivity, which is taken downwards. So the ascent of a hill, is an acclivity: the descent of the same, a declivity.
Some writers on fortification use acclivity for talus: though more commonly the word talus is used to denote the slope, whether in ascending or descending.
