Description
The infillracion race of bare, scony, runoff zones of a massive red earth soil in a semi-arid woodland was measured using a disc permeameter (waler supply potential +10 mm), rainfall simulalor and a i arge, bounded, runoff plol, The steady slate infiltration race measured with the disc permeameter was higher than Chai measured wilh the rainfall simulator, Raindrop impact and overland flow effecls wilh the rainfall simulator rearranged parlicles at Che soil surface and resulced in Che formalion or a rain-induced crust. This cruse had a lower infillralion rate than Che surface formed wilh the disc permeameler. The infillrationratcmeasured with the rainfall simulator (at an applied rainfall inlensicy of 30 mmlh) was similar 10 Chose measured during a nalural rainfall evenl (22 mmlh) wllh Che bounded runoff plol, Therefore, in some cases, Che rainfall simulalor is able lo approximale very closely the silualion for nalural rainfall,
