Abstract:
ABSTRACT: The main objective of this study was to assess the vertical distribution of water through
a soil from the Lutheran University Center of Palmas Experimental Field aiming the possible use of
sub-irrigation in the area. To represent the study area a sample of soil was collected and to simulate
the water table an Hydrological Physical Model was used. Capillary action of water was produced
after moisture distribution along the soil s profile using different levels of water on the sample,
through a mathematical model that quantifies capillary action as a function of soil porosity and texture.
The results show that for this soil capillary action exists within a 21 cm height, so the rooting system
shall be at most this distance from the water table.
