Abstract Methods for predicting unit plot soil loss the ‘Sparacia’ Sicilian (Southern Italy) site were developed using 316 simultaneous measurements of runoff and from individual bare plots varying in length 11 to 44 m. The event was directly proportional an erosivity index equal ( Q R EI 30 ) 1·47 , being ratio times single storm erosion (EI ). relationship represents a modified version USLE‐M, therefore it named USLE‐MM. By USLE‐MM, constant erodibility coefficient deduced different lengths, suggesting that this case calculated factor is representative intrinsic property. Testing USLE‐M USLE‐MM schemes other soils developing simple procedures estimating has practical importance develop method predict at erosive temporal scale. Copyright © 2009 John Wiley & Sons, Ltd.
