Water infiltration in the soil: part I cylinder infiltrometer versus sprinkler infiltrometer
[摘要] The objective of this paper was to compare values of water infiltration rate in soil, obtained with two distinct methodologies: cylinder infiltrometer and sprinkler infiltrometer. Thirty six infiltration rate curves were obtained using the cylinder infiltrometer methodology and four infiltration rate curves using a sprinkler infiltrometer. It was observed that the arithmetic mean of results from the cylinder infiltrometer methodology obtained overestimated the infiltration rate obtained with sprinkler infiltrometer and that the geometric mean and mode of the results obtained with cylinder infiltrometer approached the velocity of infiltration of water in soil obtained with the sprinkler infiltrometer.
