Definition

Capillarity in soils refers to the upward flow of water above the groundwater table.

This natural phenomenon of prevailing ascent of water in soil pores was compared, from the first decades of research, with the capillary rise of water in fine bore tubes (Fredlund and Rahardjo 1993). In order to describe this state of water movement in soils, a capillary model must be defined in terms of capillary height and capillary pressure (see Fig. 1).
