Estudo da influência da umidade inicial do solo na sua capacidade de infiltração.

Abstract

The soil infiltration capacity is this characteristic influenced by several factors, it was made test of infiltration , using rings-infiltrometer, where was varied the content of water in 0, 33, 66 e 100% of soil water available. It was evaluated the effect of moisture about the parameter of equation of infiltration of Kostiakov (f=f1.tn). The results showed what the parameters f1 and n of equation, was affected by moisture. With this , concluded what , for projects of irrigation , the infiltration capacity determination, should be doing when the soil water content is near of moisture irrigate point.
