ABSTRACT: The purpose of this research is to demonstrate that
a calibration curve can be obtained that can be used for any infiltration test,
with the double ring method, as well as an equation that helps speed up data
processing. The experimentation was carried out in eight points in Nicaragua,
of which five were distributed in Managua and three in Rivas-Nandaime. These
results can be used for purposes of other studies of interest. As a result, a
calibration curve is obtained, and an expression equal to is deduced, which will be the equation to
determine the average infiltration of a field test occupying the double ring,
for a total of 7 hours. And it is from the result that the texture of the soil
can be determined by means of the indicator table. The basic methodology
allowed analyzing the data since they are obtained, processed and analyzed,
resulting in the calibration curve for infiltration tests. Finally, an equation
was determined from the averages of the processed data, resulting in a
correlation of 0.9976, above 0.5, which means it is very high and reliable.
