▁the ▁ 5 0 ▁years ▁since ▁the ▁introduction ▁of ▁the ▁US LE , ▁many ▁other ▁soil ▁er os ion ▁models ▁have ▁been ▁developed . ▁But ▁because ▁of ▁the ▁complexity ▁of ▁soil ▁er os ion ▁and ▁its ▁constitu ent ▁processes , ▁all ▁er os ion ▁models ▁can ▁give ▁uns atisf actory ▁results ▁when ▁valid ated ▁i . e . ▁when ▁model ▁predictions ▁are ▁compared ▁with ▁real - world ▁measurements ▁of ▁er os ion . ▁Thus ▁new ▁soil ▁er os ion ▁models ▁continue ▁to ▁be ▁developed . ▁Some ▁of ▁these ▁remain ▁US LE - based , ▁e . g . ▁the ▁G 2 ▁model . ▁Other ▁soil ▁er os ion ▁models ▁have ▁largely ▁( e . g . ▁the ▁Water ▁E ros ion ▁Pred iction ▁Project ▁model ) ▁or ▁wh olly ▁( e . g . ▁the ▁R angel and ▁H ydro log y ▁and ▁E ros ion ▁Model ▁) ▁abandoned ▁usage ▁of ▁US LE ▁elements . ▁ ▁Pre vention ▁and ▁rem ed iation ▁ ▁The ▁most ▁effective ▁known ▁method ▁for ▁er os ion ▁prevent ion ▁is ▁to ▁increase ▁veget ative ▁cover ▁on ▁the ▁land , ▁which ▁helps ▁prevent ▁both ▁wind ▁and ▁water ▁er os ion . ▁Ter rac ing ▁is ▁an ▁extremely ▁effective ▁means ▁of ▁er os ion ▁control , ▁which ▁has ▁been ▁pract iced ▁for ▁thousands ▁of ▁years ▁by ▁people ▁all ▁over ▁the ▁world . ▁Wind break s ▁( also ▁called ▁shelter bel ts ) ▁are ▁rows ▁of ▁trees ▁and ▁shr ubs ▁that ▁are ▁plant ed ▁along ▁the ▁edges ▁of ▁agricult ural ▁fields
