Abstract
Assessment of soil infiltration capacity by using portable rainfall simulator
Highlights
ASSESSMENT OF THE SOIL INFILTRATION CAPACITY USING A PORTABLE RAIN SIMULATORUnder consideration is the possible assessment of the soil infiltration capacity by using a portable rain simulator to irrigate a small area without the rill erosion development
Sprinkling of runoff plots found an application with the view of studying the soil erosion in the 1940s, being associated with the study carried out by Zingg (1940)
A portable rain simulator applied in a runoff plot shaped as a cycle with the area of 0.05 m2 displayed no rill erosion (Fig. 2) [2]
Summary
Under consideration is the possible assessment of the soil infiltration capacity by using a portable rain simulator to irrigate a small area without the rill erosion development. It was shown that the small-sized runoff plots display no rill erosion and can be used for assessing the soil infiltration capacity To verify this affirmation, two experiments were conducted, one of them included a large rain simulator and a runoff plot in field (3 m long and 3 m2 in area, where the rill erosion occurred); in the other experiment carried out in laboratory with the use of soil monoliths taken in the same field a portable rain simulator and a runoff plot shaped as a cycle with the area of 0.05 m2 were used (without the rill erosion development).
