Irrigação localizada superficial por cavidades e modelo entrópico de infiltração.

Abstract

This is the study of a new alternative of localized superficial irrigation using a modify volumetric balance model that s use a unpublished new infiltration model. This infiltration model is based in the maximization of the entropy. The system purposed consists in a ground excavation around the plant base. The form of this is same as a big ring, that produces an humid bulb in the root zone equivalent to the drooping system. This cavities need to be connected by furrows that s beyond serves for being a semi impermeable conductor of water creates a micro-system of water harvesting. Root layers can be placed inside of the cavities with intention to eliminate the losses for evaporation, to prevent the growth of harmful grass and until to improve the collect income. Comparing the new entropic model with the models of Horton, Philips and the modified model of Kostiakov, the entropic one, it was determined a lesser standard error and a bigger correlation coefficient, in average of 1.5% and 8.8 % for the furrows and double ring infiltrometers respectively and a maximum of 2.5% and 68%.
