Abstract

The objective of this work was to verify the applicability of a method of infiltration used for deployment of septic tanks in scientific studies. Measures consisted in checking the time needed for the water infiltrate 1 cm in a ruler in 10-minute intervals. The values of infiltration were 100 liters/hour; 83.5 liters/hour; 50 liters/hour; 412.5 liters/hour; 125 liters/hour respectively for temporary crop, pasture, mechanized sugar cane, forest, non-mechanized sugar cane. The amount of infiltrated water varied according to type of occupation in the area, duration of such occupation, as well as soil management and conservation techniques adopted in these environments.
