Fig. 1. (A) The diagram of SAE chamber assembly system that includes a top erosion chamber containing knurled walls and a screen (350 µm) base, and a lower retainer chamber, which collects eroded soil materials. (B) Erosive strength were calculated for numerous concentric layers eroded from soil aggregates by abrasive forces exerted at the knurled wall surfaces of the SAE erosion chambers and C and texture were determined for exterior region and interior region samples collected when percentage of peeled mass reached 33.3 ± 2 and 66.7 ± 2%, respectively.
